Intracranial mature cystic teratoma

Case contributed by Dr Bruno Di Muzio


Three months a progressive headache, vomiting and seizures.

Patient Data

Age: 7 years
Gender: Male

CT brain (selected images)

The single image from a post-contrast CT of the brain demonstrates a large complex supratentorial midline lesion with cystic areas, small calcifications and a solid hypodense area located in the midline, in the pineal region. 


MRI brain (selected images)

Single images from an MRI of the brain demonstrate a very large mass is located in the region of the pineal gland with peripheral contrast enhancement. The cystic component is multi-loculated and each component demonstrates different signal intensity with some having fluid-fluid levels. There is compression of the midbrain and hydrocephalus. 

Case Discussion

This patient went on to have a tumor resection which confirmed the diagnosis of a mature intracranial teratoma. Without the benefit of macroscopic fat, it is difficult to make a firm pre-operative diagnosis.
