Surgical approaches to posterior third ventricular tumors.
A variety of surgical approaches to the posterior third ventricle and pineal region exist. The choice of approach is influenced by the exact location of the lesion, its expected pathologic findings, and the comfort level of the operating surgeon with the approach that is being considered.

Third ventricular cavernous angiomas are rare vascular malformations of the brain. We report an eight-year old boy with a rare third ventricular cavernous angioma that hemorrhaged presenting with symptoms of acute hydrocephalus. Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) showed a heterogenous ill-defined, solid and cystic intraventricular mass in the third ventricle which was...

Thalamic adhesion or Massa intermedia exists in 60% of people. Numerous limbic projections course through this wall (stria medullaris, thalamomammillary tract, median forebrain bundle and fasciculus retroflexus), hence the deficit in shor...

He became withdrawn and solitary, and subsequently developed urinary and fecal incontinence. Routine laboratory studies were unremarkable. A CT scan showed a large lob...
متن کاملThird ventricular colloid cyst and organic hypomania
(also called neuroepithelial cysts) are relatively rare i n t r a c r a n i a l lesions located in the rostral aspect of the third ventricle. They comprise approximately 0.5–1% of primary brain tumours. They occur with equal frequency in men and women. Most reported cases occur in the third to fifth decades of life.1 Although colloid cysts are histologically benign, they may obstruct the forami...
