Idiopathic retroperitoneal fibrosis (IRF) is a rare condition of unknown etiology. An unusual case of IRF exclusively located at the peripancreatic area without extension below the lower renal poles is reported.
Mesenteric panniculitis (MP) is an inflammatory process of the mesenteric fat associated with a variable amount of fibrosis. We present the CT findings in four patients with MP. In three patients CT showed a fatty mass in the root of the mesentery and surrounding the mesenteric vessels without distorting them. The fourth patient presented an unusual form of MP with radiologically visible calcifications. Diagnosis was suggested preoperatively in two cases.
INTRODUCTION: The new techniques of magnetic resonance imaging have produced a important advance in the early diagnosis of acute ischemic stroke. The diffusion weighted imaging (DWI) has a high sensitivity and specificity in the acute ischemia. CASE REPORT: 70 years old woman with previous history of hypertension and dyslipemia. The patient presented sudden vertigo with cervical neck pain and gaze problems. The physical exploration revealed right miosis, nistagmus, IX and X cranial nerve affection and ataxia. The clinical diagnosis was Wallenberg s syndrome and a medulla lateral infarction. However DWI was normal (10 hours). The neurological deficit was persistent and a repeated study disclosed a lateral infarction of the medulla. CONCLUSIONS: The sensitivity of DWI is reduced during the first 24 hours. There are false negative diagnosis mainly in small infarctions of posterior territory.
A multilocular cystic nephroma is described in a female patient diagnosed as having a mucinous cystadenocarcinoma of the left ovary, treated by surgery. It is presented as a mixed mass in the left kidney; image findings were specified with the new image diagnostic methods currently available, ultrasonography and computerized tomography. In the ultrasonographic study the mass is presented as an heterogenous image, with multiple anecogenic areas, separated by more ecogenic bands, situated mainly in the lower pole affecting all the cortical area and occasionally invading renal sinus. In the computerized tomography study a cystic mass is observed, with cysts of a different size that, after administering intravenous iodine, show a density increase in intercystical fibrous tracts. In cases with more complex image presentations, fine needle puncture is recommended, preferably in different areas in the mass in order to rule out the presence of malignant cells.
