Subependymal giant cell tumors are a well-known manifestation of tuberous sclerosis, affecting 5-15% of patients with the condition 8. While these tumors are not uncommon in tuberous sclerosis, hemorrhage into them is extremely rare. TSC is an autosomal dominantly inherited neurocutaneous syndrome that affects any organ system of the body. Two commonly affected genes underlying TSC and therefore SEGAs are TSC1 and TSC2, which encode for the proteins hamartin and tuberin, respectively. Current evidence suggests that they are of a mixed neuronal and glial lineage, although they continue to be classified as astrocytomas 5.
