PURPOSE: Malignant rhabdoid tumor (MRT) of the central nervous system (CNS) is pathologically identical to MRT of the kidney. CNS MRTs have the clinicopathological behavior of a high-grade intracranial sarcoma, and the children have a very poor prognosis. We report on three cases of primary CNS MRT with a review and summary of the pediatric literature with respect to demographic features and multidisciplinary management. PATIENTS AND METHODS: The 18 cases reviewed had a male to female ratio of 1.0 and an extremely young median age of 32 months. Our three cases of CNS MRT were treated with surgery, chemotherapy, radiotherapy, and triple intrathecal (TIT) chemotherapy similar to the Intergroup Rhabdomyosarcoma Study III guidelines for parameningeal primary tumors with intracranial extension. RESULTS: The three patients described in this report are surviving with no evidence of disease at 5 years, 2 years, and 9 months from diagnosis. Before these three cases, only four of 16 reported patients were known to have survived. One unique case in our report involved disease in the cerebral cortex, sinuses, and orbit with metastases to the subarachnoid space. This metastatic MRT responded to treatment with TIT, multiagent chemotherapy and cranial-spinal radiation after partial resection of only the cortical portion of the MRT. CONCLUSIONS: Disseminated CNS MRTs can be treated using multidisciplinary management with an approach similar to that used to treat rhabdomyosarcoma.
