Primary intracranial extra-axial and supratentorial atypical rhabdoid tumor.

Abstract : An atypical teratoid/rhabdoid tumor of the central nervous system is an aggressive infantile embryonal neoplasm, usually presenting as an infratentorial and intraparenchymatous lesion. We report on magnetic resonance imaging findings of a 22-month-old boy with a biopsy-proven primary rhabdoid tumor, presenting as a single intracranial supratentorial extra-axial mass. Based on the patient's age and imaging features (perfusion, diffusion magnetic resonance imaging, and magnetic resonance spectroscopy), a diagnosis of atypical teratoid/rhabdoid tumor was more accurate than diagnoses of meningioma and primitive neuroectodermal tumor. Although this entity is relatively rare, it should be considered in the differential diagnosis of dural-based, space-occupying central nervous system lesions.
