Primary intracranial rhabdomyosarcoma (RMS) is a rare tumor in infancy and childhood that is found in various locations in the central nervous system. The clinical course worsens rapidly, and the final outcome is poor, with a median survival time of 8-10 months. Invasion of the meninges, spontaneous intratumoral bleeding, spinal leptomeningeal CSF spreading of tumor cells, and early recurrence of the mass are the distinctive features of RMS. Diagnosis of RMS may be missed: immunohistochemical staining using specific markers (myoglobin, myosin, desmin, vimentin, enolase), along with ultrastructural studies, provide the basis for making the final diagnosis. Treatment of RMS includes surgical excision, craniospinal radiation therapy, and chemiotherapy. We report two cases of primary RMS in the CNS located in the posterior fossa and frontotemporal area. Both children underwent total surgical removal of the mass. Early recurrence of the tumor mass was noticed in both patients 2 months after surgery. Both children died shortly thereafter.
