✅Subependymal giant cell astrocytoma (SEGA) associated with tuberous sclerosis complex. 💡A growing or >1 cm lesion near the foramen of Monro suggests SEGA. Look for cortical tubers and subependymal nodules. Calcified subdural hematomas may reflect chronic VP shunt overdrainage. doi.org/10.7759/cureus.11714…
