Abstract:
A 41-year-old male presented with an ill-demarcated mass involving the left fronto-temporal lobe and the basal ganglia. Light microscopically the tumor was diagnosed as an anaplastic oligoastrocytoma. Electron microscopy revealed several cytoplasmic crystalline inclusions in tumor cells of oligodendroglial lineage. No crystalline inclusions were membrane bound. The morphologic features with unique ultrastructural findings are presented.
