Scrotal collections: pictorial essay correlating sonographic with magnetic resonance imaging findings / Coleções na bolsa testicular: ensaio iconográfico correlacionando achados ultrassonográficos com a ressonância magnética

The present study is aimed at describing scrotal collections observed at ultrasonography and magnetic resonance imaging. The authors describe the main features of hydrocele, hematocele and pyocele, as well as the most common causes, clinical manifestations and associated diseases, with a brief review of the embryology and anatomy of the scrotum. Collections are frequently found in the evaluation of the scrotum, which is often performed on an emergency basis, and in most cases can be differentiated by means of imaging studies. With the consolidation of magnetic resonance imaging as the method of choice complementary with ultrasonography, the authors also describe magnetic resonance imaging findings of scrotal collections as well as the situations where such method is indicated.

O objetivo deste trabalho é descrever coleções na bolsa testicular vistas na ultrassonografia e na ressonância magnética. São descritas as principais características da hidrocele, hematocele e piocele, assim como as causas mais comuns, manifestações clínicas e doenças associadas, com uma breve revisão da embriologia e anatomia da bolsa testicular. Coleções são achados frequentes na avaliação da bolsa testicular, muitas vezes realizada em caráter de urgência, e podem ser diferenciadas por meio de exames de imagem. Com a consolidação da ressonância magnética como exame de escolha em complemento à ultrassonografia, são também descritas as características das coleções escrotais na ressonância magnética, além das indicações para a sua realização.

Leiomiossarcoma de veia cava inferior / Leiomiossarcoma of the inferior vena cava

Leiomyosarcoma of the inferior vena cava is an extremely rare tumor, and it is reported to have a poor prognosis. The clinical findings are nonspecific and may precede the diagnosis by several years. Symptoms depend on the location and extension of the tumor. A complete surgical resection is the only proven therapeutic modality that prolongs the survival in patients with this lesion. We report a case of a 50 year-old patient with inferior vena cava leiomyosarcoma, who was submitted to a surgical treatment.
