J Pak Med Assoc Jan ;53(11):573-5.

This 8 month old male infant presented with a two month history of increasing head size, lethargy, decreased activity and inability to sit. Examination revealed an irritable child with a tense anterior fontanelle and head circumference of 45 cm. (greater than ninetieth percentile of normal). Tone was increased in all four activities but there was no paresis. There was bilateral papilloedema. T1 weighted MR scan with contrast showed a homogenously enhancing mass within the third ventricle. This mass measured 8x5x5 cm. There was associated hydrocephalus of the lateral ventricles. Cerebral angiography revealed a moderately vascular tumor fed by anterior choroidal artery.At surgery, a right frontal craniotomy was performed and a transcortical transforminal route was undertaken to approach the tumor. It was a cauliflower-like mass in the lateral ventricle protruding out of the foramen of Monro. He had focal left sided seizures during the post-op period. Post-op contrast enhanced CT scan showed bilateral subdural collections and residual tumor. The second stage procedure was performed one week later.
