Rapid regrowth of solitary subependymal giant cell astrocytoma--case report.
A 48-year-old female presented with a subependymal giant cell astrocytoma (SEGA) without tuberous sclerosis manifesting as memory and mental disturbance. Magnetic resonance imaging showed a huge mass which was well-demarcated and extended from the anterior horn of the right lateral ventricle to the septal area on the right side. Surgery was performed with partial removal of the tumor. The histological diagnosis was typical SEGA. One year postoperatively, follow-up magnetic resonance imaging revealed marked regrowth of the tumor. Total resection of the tumor was performed. Microscopic and immunohistochemical studies could not identify the cause of the rapid regrowth. SEGA can regrow rapidly after partial removal of the tumor.
