We describe a rare case of idiopathic lenticulostriate artery (LSA) aneurysm in a 15-year-old girl who presented in the emergency department with a sudden onset of severe headache and left hemiparesis. Computed tomography revealed an intracerebral hemorrhage in right basal ganglion. Angiography revealed a LSA aneurysm. The patient underwent right frontal craniotomy for aneurysm removal. Overall, the patient experienced a positive outcome after surgery for a ruptured LSA aneurysm. Following the operation, the patient participated in a 1-week rehabilitation program, which improved her left hemiparesis. We observed a positive outcome with surgical treatment for the ruptured LSA aneurysm, which was probably improved by early surgical intervention.
