Extraventricular subependymal giant cell tumor in a child with tuberous sclerosis complex.
Subependymal giant cell tumors (SGCTs) are observed in 5-20% of patients with tuberous sclerosis complex (TSC) but account for approximately 25% of neurological morbidity. The authors report the case of a 7-year-old girl with TSC and multiple cortical tubers who presented with worsening seizures in the context of the rapid growth of a cystic, calcified, extraventricular SGCT in the right frontal lobe, initially thought to represent a cortical tuber. The tumor and surrounding tubers were excised, and clinical seizures resolved. This is the first report of an extraventricular SGCT in a child with TSC outside the neonatal period.
