Background: Meningiomas are common central nervous system tumors with a wide range of morphologic variants, the pathogenesis being their complex embryogenesis. Intracranial meningiomas with heterogenous histopathology in the same lesion are common in low-grade meningiomas but less frequent in recurrent and high-grade variants.
Case Description: A 75-year-old male presented elsewhere a year ago with complaints of slurred speech.

Melanotic schwannoma is a rare form of pigmented neural tumor commonly arising from the posterior spinal nerves and ganglia. Two variants have been described, psammomatous and nonpsammomatous. 50% of psammomatous tumors are associated with Carney complex.

Article Synopsis
- Pleomorphic xanthoastrocytoma (PXA) is typically seen as a low-grade brain tumor (WHO Grade-II), but instances of more aggressive forms with worse prognoses have emerged, labeled as "PXA with anaplastic features."
- The case involves a 9-year-old girl suffering from recurrent headaches, seizures, and academic difficulties, with MRI scans showing a problematic mass in the brain and signs of a high-grade glial tumor.
- Surgical removal of the tumor led to findings showing a complex mixture of abnormal cells, confirming the diagnosis of pleomorphic xanthoastrocytoma with anaplastic features due to specific histological characteristics like abnormal cell structures and aggressive cell behavior.
