Macroscopic hematuria regards the 4% to 20% of all urological visits. Renal artery aneurysms (RAAs) are detected in approximately 0.01%-1% of the general population, while intraparenchymal renal artery aneurysms (IPRAAs) are even more rarely detected in less than 10% of patients with RAAs. We present a case of a 58-year-old woman that came into the emergency room (ER) complaining of a gross hem...

INTRODUCTION We report on a very rare case of a supratentorial primitive neuroectodermal tumor in an adult, which presented with intracerebral hemorrhage, and review the relevant medical literature. CASE PRESENTATION A 42-year-old Caucasian man complained of a sudden headache and nausea-vomiting. The patient rapidly deteriorated to coma. An emergency computed tomography scan showed an extensi...

Remote intraparenchymal hemorrhage after clipping of a ruptured aneurysm is rare. The pathogenesis is variable, and the therapeutic strategies remain controversial, because the natural history is unclear. Here we report a woman with subarachnoid hemorrhage (SAH), who had an aneurysm of the anterior communicating artery identified by computed tomography angiography (CTA). A 51-year-old women, wh...

Intracranial cavernomas, initially described as rare lesions [1], have been seen with increasing frequency since the advent of MR imaging [2-5]. MR features of cavernomas are highly suggestive of the diagnosis, although not pathognomonic. Cavernomas are classically intraparenchymal lesions and occult to angiography. They have a pseudotumoral growth [6] and a low potential for life-threatening h...

Two cases of neurocutaneous melanosis are presented. MR showed hyperintense areas in the brain on short-repetition-time/short-echo-time sequences, compatible with intraparenchymal melanin deposits. No leptomeningeal abnormality was seen.

Ipsilateral third nerve palsy with early pupillary enlargement is an important sign of transtentorial herniation from a supratentorial mass lesion. A case of frontal, intraparenchymal haemorrhage is reported in which the first ocular manifestation of transtentorial herniation was enlargement of the contralateral pupil. The ipsilateral pupil dilated only after complete oculomotor palsy of the co...

A 41-year-old male with cough and subtle chest radiograph opacities demonstrated bilateral intraparenchymal pulmonary artery aneurysms on computed tomography (Figs 1 and 2). Causes include congenital cardiac defects, pulmonary arterial hypertension and infection. The patient had been treated during childhood for Staphylococcal pneumonia prior to ventricular septal defect closure. He declined fu...
