title: Mural tumors with cysts in the cerebral hemispheres of children.
abstract: Thirteen infants and children with mural tumors (i.e., cysts with mural nodules) in the cerebral hemisphere are presented. The tumors comprise five benign astrocytomas, three ependymomas, two choroid plexus papillomas, one oncocytoma, one hamartoma, and one primitive neuroectodermal tumor. Computed tomography showed well-enhanced mural nodules. Cyst walls did not enhance in any but one, in which the enhancement was attributed to hemorrhage in the cyst. None of the cyst walls contained neoplastic cells. Cerebral angiography was performed in all patients, and five showed extensive vascularity in the tumor nodule. The importance of preoperative angiography is emphasized. Total extirpation of the mural nodule without excision of the cyst wall led to excellent prognosis for these patients.
