Signs and symptoms
Because of their massive growth, pineocytoma symptoms are related to increased intracranial pressure. Some common symptoms of pineocytomas include
Causes

chromosomal abnormalities. There are no known risk factors for pineocytomas.[4]
Diagnosis
Pineocytomas typically present on a
homogeneous, hypodense, and sometimes have central or peripheral calcification. On an MRI a pineocytoma often appears isointense or hypointense in T1-weighted scans. However, they usually appear hyperintense on T2-weighted scans. The diagnosis of a pineocytoma is confirmed by a brain biopsy.[4]

The main treatment options for pineocytomas are gross total resection, subtotal resection, and radiation.[5]
