Figure 1: Urgent magnetic resonance imaging shows that the pineal gland tumour had increased in size. Axial and sagittal T2 MRI exhibits isointense to grey matter with areas of cyst formation shown by red arrow. Low signal intensity in the posterior part of the mass represents calcification shown by yellow arrows. The pineal gland tumour compressed the aqueduct of Sylvius causing hydrocephalus. The MRI features suggested of germinoma.
