Bilateral posterior cerebral artery stroke following transtentorial herniation caused by a subependymal giant cell astrocytoma in a patient with tuberous sclerosis: a case report

Tuberous sclerosis complex (TSC) is an autosomal dominant multisystem disorder, first described by Bourneville [1]. TSC patients present with three distinct intracranial lesions: subcortical tubers, subependymal nodules, and subependymal giant cell astrocytomas (SEGA) [1,2]. Despite its benign histopathology, SEGA can result in a variety of severe events that may substantially increase the mortality and morbidity of TSC patients [3]. This is due to their preferential proximity to the foramen of Monro, Bilateral posterior cerebral artery stroke following transtentorial herniation caused by a subependymal giant cell astrocytoma in a patient with tuberous sclerosis: a case report Joong-Goo Kim, MD; Jay Chol Choi, MD, PhD; Hong Jun Kim, MD; Jong Kook Rhim, MD; Tae Jun Jung; Chang-Lim Hyun, MD, PhD; Jin Deok Joo, MD
