Patient Data

CT

Single image through the brain demonstrates a soft tissue mass in the region of the pineal gland with eccentric calcification (anterior) and evidence of hydrocephalus. 

MRI brain

MRI

An enhancing mass in the region of the pineal gland is present which demonstrates restricted diffusion on DWI. A tongue of tissue is seen extending inferiorly through the aqueduct, obstructing it and resulting in hydrocephalus with transependymal edema. 

Case Discussion

The patient went on to have surgery which confirmed the diagnosis of a pineoblastoma, as wells as confirming extension of the mass down aqueduct.
