Pineal Tumor

Pineal tumors are rare neoplasms located in the pineal gland, including germinomas and pineocytomas. Clinical features include headache, hydrocephalus, Parinaud syndrome, and endocrine disturbances. Pathophysiology involves mass effect and local invasion. Diagnosis relies on MRI, serum/CSF tumor markers, and histopathology. Management includes surgical resection, radiotherapy, or chemotherapy depending on tumor type; prognosis varies by histology and treatment response.
