Quadrigeminal Plate Tumor

Quadrigeminal plate tumors are rare lesions arising from the tectal region of the midbrain. Clinical manifestations include hydrocephalus, cranial nerve deficits, and Parinaud syndrome. Pathophysiology involves mass effect on surrounding midbrain structures. Diagnosis relies on MRI and histopathologic confirmation. Management includes surgical resection, CSF diversion, and adjuvant therapy depending on tumor type; prognosis depends on histology and surgical outcomes.
