Two Cases of Tuberous Sclerosis Associated with Subependymal Giant Cell Astrocytoma

Neurosurgical intervention in the syndrome is discussed in the light of two recently treated cases, one of which was admitted due to acute hydrocephalic attack, the other was confirmed by the typical computed tomographic findings as well as the classic triad of adenoma sebaceum, mental retardation and epilepsy. There cases had no family historty and were probably the result of new mutations and variable penetrance. Transcallosal microsurgical excision of tumor was accomplished in both cases and subependymal giant cell astrocytoma was confirmed. The hydrocephalus resolved but subduroperitoneal shunt was required in one case.
