Intraventricular neoplasms are readily seen on cross-sectional images,consideration of the tissue within and the clinical findings provide the means to limit the differential diagnosis when analyzing an intraventricular mass on an imaging study. Central neurocytomas are rare, slow-growing, intraventricular tumors that are of neuronal origin, typically located in the lateral ventricles, near the...

Intraventricular schwannomas are rare primary brain tumors, with fewer than 25 cases reported in the literature. Here, we present the case of a 20-year-old male patient with a 2 year history of blurry vision and dysesthesia involving his right occiput and upper neck. Imaging demonstrated a homogeneously enhancing mass located within the atrium of the right lateral ventricle with associated righ...

We present a patient acutely ill from severe tuberculous meningo-encephalitis, in whom acute hepatic and renal failure, due to intercurrent septic shock, precluded the administration of full systemic dosage of antituberculous drugs. Daily direct intraventricular administration of 5 mg rifampicin, via a subcutaneous Ommaya reservoir connected to a catheter placed in the right lateral cerebral ve...

In patients with high-grade atherosclerotic stenosis or occlusion of the extracranial cerebral arteries, subarachnoid hemorrhage (SAH) may occur, potentially due to rupture of fragile dilated pial collateral vessels. This association has been well described in Moyamoya disease. There are only few cases in the literature that reported SAH due to bilateral carotid artery stenosis but intraventric...

The nature of ventriculomegaly in dogs is still a matter of debate. Signs of increased intraventricular pressure and atrophy of the cerebral white matter have been found in dogs with ventriculomegaly, which would imply increased intraventricular pressure and, therefore, a pathological condition, i.e., to some extent. Reduced periventricular blood flow was found in people with high elevated intr...

Transthoracic echocardiography demonstrated an intraventricular mass between the posterior mitral leaflet and the lateral left ventricular (LV) free wall in a 61-year-old man. Because of this uncommon localization an intracardial tumor, an endocarditis of the mitral valve or an intraventricular thrombus was suspected. Magnetic resonance imaging (MRI) ruled out an intracardial tumor and revealed...

Left ventricular 'relative wall thickness', determined from the ratio between echocardiographic measurements of end-systolic wall thickness and cavity transverse dimension, was related to peak systolic intraventricular pressure in 15 normal subjects, in 15 patients with left ventricular volume or pressure overload without aortic stenosis, and in 23 patients with aortic stenosis. All these patie...
