Abstract
- Ischemic stroke caused by spontaneous thrombosis of posterior inferior cerebellar artery (PICA) aneurysm has been rarely reported. A 52-year-old man presented with sudden headache, dizziness, and gait disturbance. Diffusion-weighted MRI showed acute infarction in left PICA territory. A saccular aneurysm with internal thrombus at the distal PICA was detected by CT angiography and conventional angiography. The thrombus resolved spontaneously at 2 months after stroke onset with aspirin medication. At that time, endovascular coiling was underwent successfully to prevent aneurysmal rupture.
