RESUMO
We describe here a case of vulvar epithelioid sarcoma. Epithelioid sarcoma is a malignant appendicular skin tumor that is rarely of vulvar origin. Magnetic resonance imaging (MRI) revealed a solid mass with an ulcer-like lesion and multilobulated contour. To our knowledge, this is the first case of vulvar epithelioid sarcoma described in the MRI literature.

We describe the case of a 63-year-old woman with a large Bartholin's duct cyst that showed high signal intensity on T1- and T2-weighted magnetic resonance (MR) images. Although Bartholin's duct cyst is the most frequent cystic lesion of the vulva, such a giant cyst is rare.

Gerstmann-Sträussler-Scheinker syndrome (GSS syndrome) is a rare hereditary disorder caused by prion protein gene mutation. We present the case of a 31-year-old man, whose signs and symptoms gradually progressed from loss of attention while driving at onset to headache, dysarthria, night sweat, fatigue, and dysgraphia. Diffusion-weighted imaging (DWI) of the brain after admission showed high signal intensities in the bilateral caudate nuclei, bilateral thalami, and cerebral cortices that suggested transmissible spongiform encephalopathy. The patient was diagnosed with GSS syndrome on genetic study. Magnetic resonance (MR) imaging of the entire period of sickbed showed gradually changing signal intensities and cerebral atrophy. We present a series of images and discuss the reasons for the abnormal intensities in GSS syndrome that vary among reported cases.

A case of retroperitoneal chronic expanding hematoma complicated with hydronephrosis, which was difficult to diagnose preoperatively, is reported. The patient was a 70-year-old man. An 18 cm mass was detected in the right retroperitoneal space on abdominal CT screening. There were small calcifications in the periphery of the mass that were strongly enhanced in the delayed phase of dynamic CT. The mass involved the right ureter and iliopsoas muscle, resulting in severe hydronephrosis. The histological diagnosis was chronic expanding hematoma.
