Cysts with mural tumor nodules in the cerebral hemispheres.

Ten cases of cystic tumor with mural nodules in the cerebral hemispheres are reported. The tumors include five benign astrocytomas, two meningiomas, one ependymoma, one neuroblastoma, and one hemangioblastoma. In all cases, computed tomography showed enhancing mural tumors without enhancement of the cyst wall. Complete removal of the mural tumor without excision of the cyst is the goal of operation. The prognosis for patients with cystic tumors with mural nodules is excellent, clearly better than that of solid tumors.
