Bilateral intraventricular mass in a child.

An 8-year-old boy presented with a history of holocranial headache for 4 weeks which was mild to moderate in intensity. There was history of intermittent vomiting for the same duration. The patient was drowsy for the last 10 days. Non-contrast CT scan of head showed a space-occupying lesion in lateral ventricles with hydrocephalus. MRI showed a large lobulated well-defined heterogeneous mass lesion filling up both lateral ventricles at the posterior and temporal horns, bilaterally reaching up to the level of the foramen magnum. The mass lesion was hypointense on T2-weighted images (T2W) and isointense to grey mater on T1W images. On contrast images there was intense homogeneous enhancement seen at the lesion (Fig. 1). Right fronto-temporo-parietal craniotomy with decompression of the tumor was performed. Perioperatively, the tumor was yellowish in color, firm, not able to be aspirated and minimally vascular. Clinical diagnosis of choroid plexus tumor was considered.
