Título: Rim em Panqueca ­ Um Achado Incomum / Pancake Kidney ­ An Unusual Finding
Fonte: Rev. Salusvita (Online);37(4):945-951, 2018.
Idioma: pt.
Resumo: Introdução: o rim em panqueca foi descrito pela primeira vez por Looney e Dodd (1926), mas apresenta outras nomenclaturas como "bolo", "disco", "rosca" e "rim em escudo", porque produz uma massa em forma de anel ou em forma de rosca. É uma ectopia renal congênita fundida muito rara. Objetivo: relatar um caso raro de rim em panqueca associado a apendicite. Materiais e Métodos: revisão do prontuário, registro fotográfico dos métodos diagnósticos e revisão da literatura. Resultados: jovem de 15 anos de idade, do sexo masculino, com dor em cólica no hipogástrio há dois dias com vômitos há um dia. A tomografia computadorizada demonstrou apendicite e uma massa lobulada fundida situada na cavidade pélvica que se estende de L2 a L4 com ureteres inserindo-se separadamente na bexiga urinária, caracterizando rim em panqueca. Conclusão: relatamos um caso de rim em panqueca, entidade muito rara e pouco relatada na literatura médica, muitas vezes insuspeitada na avaliação clínica inicial, porém que pode causar complicações, tais como a litíase renal e a hipertensão arterial.

Introduction: pancake kidney was first described by Looney and Dodd, but presents other nomenclatures such as "cake", "disk", "doughnut" and "shield kidney" because it produces a ring-shaped or doughnut-shaped mass. It is a very rare fused congenital renal ectopia. Objective: to report a rare case of pancake kidney associated with appendicitis. Materials and Methods: We carried out a review of medical records, photographic record of diagnostic methods and review from the literature. Results: 15 year old male patient with colic pain in the hypogastrium two days ago with vomiting a day ago. Computed tomography scan showed appendicitis and a fused lobulated mass located in the pelvic cavity extending from L2 to L4 with ureters inserting separately into the urinary bladder, characterizing pancake kidney. Conclusion: pancake kidney is an entity very rare and little reported in the medical literature, often unsuspected in the initial clinical evaluation, but that can lead to complications such as renal lithiasis and arterial hypertension.

Título: Tratamiento multidisciplinar del leimiosarcoma de vena cava inferior / Multidisciplinary treatment of leiomyosarcoma of inferior cava
Fonte: Rev. cir. (Impr.);72(1):72-75, feb. 2020. ilus.
Idioma: es.
Resumo: Resumen Introducción Los leiomiosarcomas de la vena cava inferior son tumores raros, sólo hay 300 casos descritos en la literatura. Su incidencia es mayor en mujeres, suelen aparecer entre los 50-60 años, y presentan una progresión lenta y mal pronóstico. Los síntomas son inespecíficos haciendo que el diagnóstico se realice de forma tardía, éste se realiza mediante pruebas de imagen y biopsia guiada. Caso clínico Se presenta el caso de un varón de 73 años con diagnóstico de leiomiosarcoma de la vena cava inferior, como hallazgo incidental en TC de control, tratado mediante radioterapia neoadyuvante, cirugía y radioterapia intraoperatoria. Discusión El único tratamiento que ha descrito modificaciones en la supervivencia es la cirugía. El papel de la adyuvancia y neoadyuvancia en estos tumores es muy controvertido. La elección de la actitud terapéutica dependerá de la localización del tumor, tamaño, la relación con estructuras adyacentes y la presencia de circulación colateral.

Introduction Leiomyosarcomas of the inferior vena cava are rare tumors, with fewer than 300 cases reported. Its incidence is higher in females, usually appear in the sixth decade and they have a slow-growing and poor prognosis. Symptoms are generally non-specific. Diagnosis is made with imaging studies and guided biopsy. Clinical Case We report a case of a 73-year-old male patient with leimyosarcoma of the inferior vena cava treated by neoadjuvant radiotherapy, surgery and intraoperative radiotherapy. Discussion Surgery is the only treatment that can improve the survival. The role of the adjuvancy and neoadjuvancy is very controversial. Surgical management is determined by the location of the tumour, the relationship with adjacent structures and the presence of collateral veins.

Título: Pulmonary alveolar microlithiasis: Incidental finding - should we Ignore?
Fonte: Autops. Case Rep;10(1):2019133, Jan.-Mar. 2020. ilus.
Idioma: en.
Resumo: Pulmonary alveolar microlithiasis (PAM) is a rare entity, presenting mostly as an incidental finding. This disease has an autosomal recessive inheritance with inactivating mutations in the gene "solute carrier family 34 member 2". The present study was conducted to bring attention to this rare though preventable disease. The study was a cross-sectional descriptive study, conducted at the Department of Pathology, of a tertiary care hospital in New Dehli-India. PAMs were incidentally seen in two patients diagnosed with micronodular hepatic cirrhosis leading to reanalysis of 212 autopsies, retrospectively. Statistical analysis was done using Stata 14.0. We observed three forms (Type A, B and C) of round hyaline bodies measuring in diameter with thin delicate, radiating fibrils. These bodies were PAS positive, showed black discolouration of the pigment with von Kossa stain and birefringence on polarized microscopy using Congo red stain, however the refringence was light green as compared to apple green birefringence seen with amyloid deposition. PAM has a slow progressive course leading to a high rate of incidental detection. Drugs known to inhibit the micro-crystal growth of hydroxyapatite may slow the disease progression. The family members of patients with PAM may also be kept on follow up with regular imaging. Key messages: It is important to bring out the incidental finding as, seemingly innocuous observations may provide valuable insight into incurable diseases, especially rare diseases.

Título: ¿Como optimizar el diagnóstico funcional de los incidentalomas suprrarenales? Importancia de un estudio protocolizado / How to optimize the functional diagnosis of suprarenal incidenta- lomas? Importance of a protocolized study
Fonte: Rev. chil. endocrinol. diabetes;11(3):108-113, jul. 2018. ilus.
Idioma: es.
Resumo: Adrenal incidentalomas are an increasingly common pathology. Although historically they have been considered largely non-functioning, recent evidence suggests that the usually performed study is incomplete and/or not sensitive enough. In the last decade the clinical spectrum of adrenal hypercortisolism has expanded considerably, including milder cases which are also associated with cardiovascular morbidity and even mortality. Furthermore, primary aldosteronism has also expanded beyond the classic phenotype with advanced vascular damage, resistant hypertension and hypokalemia, currently including asymptomatic, normotensive and normokalemic patients. For this reason, a correct protocolized study is essential in all adrenal incidentalomas, including a precise radiological characterization, as well as a systematic hormonal evaluation using more sensitive cut points. The findings of this workup are relevant, because they allow a more individualized approach to the medical and surgical management of these patients.

Los incidentalomas suprarrenales son una patología cada vez más frecuente. Si bien históricamente han sido considerados no funcionantes en su gran mayoría, evidencia reciente sugiere que el estudio habitual es incompleto y/o poco sensible. En la última década el espectro clínico del hipercortisolismo de origen adrenal se ha ampliado de forma considerable, incluyendo casos leves que también se asocian a morbilidad cardiovascular e incluso mortalidad. Por otro lado, el hiperaldosteronismo primario también ha expandido su fenotipo más allá del clásicamente descrito con daño vascular avanzado, hipertensión resistente e hipokalemia, abarcando en la actualidad a pacientes asintomáticos, normotensos y normokalemicos. Por esta razón es imprescindible un correcto estudio protocolizado en todo incidentaloma suprarrenal, incluyendo una precisa caracterización radiológica, así como una evaluación hormonal sistemática utilizando puntos de corte más sensibles. Los hallazgos de este estudio son relevantes, pues permiten guiar de forma más individualizada el manejo médico y quirúrgico de estos pacientes.

Título: Frecuencia de malignidad en incidentalomas tiroideos detectados con tomografía por emisión de positrones/tomografía computada (PET/CT) con F18-FDG de cuerpo entero / Frequency of malignancy in thyroid incidentalomas detected by whole body 18F-FDG PET/CT
Fonte: Rev. méd. Chile;148(1):10-16, Jan. 2020. tab, graf.
Idioma: es.
Resumo: Background: Thyroid incidentalomas detected by 18F-Fludeoxyglucose (FDG) PET/CT are defined as an incidental and unexpected thyroid focus present in a patient studied for a non-thyroid disease. Aim: To assess the frequency of malignancy of nodular thyroid incidentalomas, and their association with 18F-FDG avidity (standard uptake value (SUV) max). Material and Methods: Whole body PET/CT performed from December 2008 to December 2017 were reviewed selecting those that showed nodular thyroid foci. Glands with diffuse increased uptake were excluded. Thyroid ultrasonography and fine-needle aspiration cytology (FNAC) performed after PET/CT were reviewed. Bethesda score and SUVmax were correlated. Results: Of 5,100 whole body 18F-FDG PET/CT, 119 showed a thyroid nodular uptake (2.3%). Forty eight percent of these patients were studied with FNAC or surgery, 50% of which (29/58) were confirmed as malignant. Benign nodules showed significantly lower 18F-FDG uptake (n = 20, SUVmax: 3.5 ± 1.7) than Bethesda V-VI (n=24, SUVmax: 8.2 ± 5.2) and thyroid metastases (n=5, SUVmax: 6.3 ± 2.1). The best cut-off value to distinguish between benign and malignant nodules was a SUVmax of 5.0, with a sensitivity of 76% (95% confidence intervals (CI) 56-90%), a specificity of 85% (95% CI 62 - 97%), and positive likelihood ratio of 5 (95% CI 1.8 - 14.6). The size of the thyroid nodule was not predictive of malignancy. Conclusions: Half of nodular thyroid incidentalomas detected by 18F-FDG PETC/CT are malignant. A nodule with a SUVmax ≥ 5,0 is highly suggestive of malignancy, regardless of its size.

Título: Importance of ectopic thyroid tissue detected in the midline of the neck: single center experience
Fonte: Arch. endocrinol. metab. (Online);60(3):231-235tab, graf.
Idioma: en.
Resumo: Objective Ectopic thyroid tissue (ETT) is a rare abnormality of the thyroid gland and the true prevalence and importance is not known. The aim of this study was to evaluate ultrasonography (US) guided fine needle aspiration biposy (FNAB) results, sonographic features, and frequency of ETT detected in the midline of the neck. Subjects and methods Five thousand five hundred and twenty outpatients who were referred to our thyroid clinic between September 2010 and April 2012 and underwent thyroid US, were retrospectively analyzed. Patients with ETT, detected in the midline of the neck in US were included in the study. Thyroid functions, sonographic features, and US guided FNAB results were evaluated. Results There were 81 (81.8%) female and 18 (18.2%) male patients with a mean age of 50.9 ± 11.7. The ETT in the midline was present in 1.79% (99/5,520) of the patients. In the majority of the patients, benign sonographic features (isoechoic, regular margin, type 1 vascularization) were detected. There were 92 (92.9%) patients with a previous history of thyroidectomy and all were histopathologically benign. In 7 (7.1%) patients, there was no history of thyroid operation. FNAB results of ETT were benign. Conclusion This study evaluated the importance of ETT detected incidentally in the midline of the neck. Especially in patients with a history of thyroidectomy, the thyroid masses in the midline of the neck can be found as incidental with imaging methods. Our results suggests that the incidence of malignancy in this group is much lower than orthotopic thyroid nodules and they are often benign.

Título: Hallazgo radiográfico de cuerpo extraño en piso de seno maxilar de sujeto asintomático / Radiographic finding of a foreign body in the maxillary sinus floor of an asymptomatic subject
Fonte: Int. j. odontostomatol. (Print);14(2):150-153, June 2020. graf.
Idioma: es.
Resumo: El seno maxilar (SM) es una cavidad par presente en el hueso maxilar, que puede presentar diversas alteraciones o lesiones patológicas factibles de ser pesquisadas mediante estudios imagenológicos. En este sentido, la opacidad, el ocupamiento y/o engrosamiento de las mucosas son los signos orientadores para el diagnóstico de patologías en estas estructuras, las que pueden ir desde sinusitis, hasta antrolitos, pasando por hipoplasias, pseudoquistes u osteomas. En el siguiente reporte presentamos el caso de una mujer de 75 años de edad en la cual mediante examinación radiográfica de rutina se observa un cuerpo extraño en el SM derecho en relación a diente 1.6. De acuerdo a esto, se solicitó una tomografía computarizada cone-beam (CBCT) para evaluar posibles implicancias con tratamiento dental rehabilitador. Al examen se observan dos estructuras de alta densidad (densidad metálica), redondeadas, una al lado de la otra, en contacto inmediato a la cortical sinusal sin comprometerla. También se observa una cortical sinusal conservada en todo su recorrido y discreto engrosamiento mucoso en relación a dichas estructuras. En consideración con los antecedentes de la paciente, se opta por un manejo conservador del hallazgo mediante controles periódicos. Se propone la hipótesis de la formación de un antrolito de origen exógeno, que se corresponde con el historial de tratamiento endodóntico en la zona. El diagnóstico diferencial de los hallazgos radiográficos encontrados es fundamental para establecer los lineamientos terapéuticos de nuestros pacientes, por ello es importante contar con personal clínico capacitado para la interpretación de las imágenes.

The maxillary sinus (SM) is an even cavity present in the maxillary bone, which may present a number of pathological alterations or lesions that can be investigated through imaging analysis. In this sense, opacity, location and / or thickening of the mucous membranes are guides for the diagnosis of pathologies in these structures. These can range from sinusitis, to antrolites, to hypoplasias, pseudocysts or osteomas. In this study the case of a 75-year-old woman is presented. During routine radiographic examination, a foreign body was observed in the right MS in relation to tooth 1.6. A cone-beam computed tomography (CBCT) was requested to evaluate possible rehabilitative dental treatment. Upon examination, two highdensity rounded structures (metal density) adjacent to each other were noted. The structures were in direct contact with the sinus cortex without compromising it. Furthermore in relation to the above structures, scant cortical sinus was observed throughout its course, as well as slight mucous thickening. Considering the patient's background, it was determined to use conservative treatment through periodic controls. Hypothesis of an exogenous mass is proposed, corresponding to the history of endodontic treatment in the area. In view of the differential diagnosis of radiographic findings found, it is essential to implement therapeutic guidelines for patients and have trained clinical staff available to interpret the images.
