A case of acute spontaneous subdural hematoma associated with fibromuscular dysplasia

Abstract

We report the rare case of a 44-year-old female with acute spontaneous subdural hematoma probably associated with fibromuscular dysplasia (FMD). She was suddenly presented with headache and consciousness disturbance. The head CT revealed thin acute subdural hematoma in bilateral convexity and craniovertebral junction. Angiography revealed stenosis of bilateral extra-cranial internal carotid arteries and unruptured saccular aneurysm of bifurcation of internal carotid artery and ophthalmic artery. She suffered from persistent severe hypertension. We confirmed the existence of renovascular stenosis by abdominal ultrasonic examination and reached the clinical diagnosis FMD. After 7 months, percutaneous transluminal angioplasty was performed and her blood pressure came under control.
