Endovascular Treatment of Symptomatic Radiation-Induced Basilar Artery Stenosis 25 Years after Medulloblastoma

Abstract

Intracranial stenosis as late sequela after cerebral radiation therapy for medulloblastoma is an exceptionally rare finding. We report for the first time a case of 31-year-old patient with a history of medulloblastoma 25 years ago and now presenting with radiation-induced high-grade basilar stenosis and recurrent ischemic symptoms despite best medical therapy. The stenosis was treated successfully with angioplasty followed by stenting using a self-expandable microstent. Additionally, MRI revealed multiple cavernomas, illustrating that radiation-induced microbleeds may occur.

Key words

radiation-induced intracranial vessel stenosis - endovascular treatment - parenchymal involvement - flat detector computed tomography (FD-CT)
