Presentation
Three months of progressive headache, vomiting and seizures.
Patient Data
Note: This case has been tagged as "legacy" as it no longer meets image preparation and/or other case publication guidelines.
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.
Single images from an MRI of the brain demonstrate a very large mass 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.
