Figure 4: Urgent CT scan of the brain. It shows an enlargement of pineal gland causing obstructive hydrocephalus and cerebral oedema. Contrastenhanced CT scan of the brain exhibits a heterogeneously enhancing, lobulated, mixed solid and cystic mass at pineal gland region shown by yellow arrows. Peripheral calcification is shown by orange arrows and cystic region shown by red arrow consistent with pineal teratoma. It also shows the presence of hydrocephalus and cerebral oedema evidenced by generalised effacement of the cerebral sulci.
