The angiographic, clinical, and genetic characteristics of fibromuscular dysplasia (FMD) are reviewed in 37 patients (mean age 48 years) selected from a pool of 4000 angiograms of carotid or vertebral arteries. FMD was a neglected pathogenic factor in 28 patients with hemorrhagic or ischemic cerebral lesions. The aneurysms found in 19 patients had conventional appearance and were mainly located in the internal carotid or middle cerebral arteries and on the same side as the most affected cervical artery, which suggests that aneurysms and FMD are pathogenically related. A clinical syndrome is presented where headache, ECG-abnormalities, hypertension, mental distress, tinnitus, vertigo, arrhythmia, TIA, and syncope are frequent components. Hemicrania, sometimes combined with ipsilateral Horner's Syndrome, was found in patients with advanced lesions in the carotid artery of the same side. An associated occurrence of stroke in pedigrees, especially among young and middle aged females, indicates that FMD in the majority of cases in inherited as an autosomal dominant trait with reduced penetrance in males.

The clinical and neuroradiological features of 127 patients with ischemia of the posterior cerebral artery (PCA) and a positive CT scan (n = 122) or pathological angiography findings (n = 63) were analyzed. Unilateral headache was the most common presenting symptom (50%), making complicated migraine an important differential diagnosis. Clinical findings were visual field deficits (93%), sensory (29%), motor (28%), and neuropsychological deficits (25%). Infarcts, including the thalamus (n = 27), were mostly associated with sensory and slight motor deficits. Our findings suggest that motor deficits in PCA ischemia, particularly if minor and reversible, are likely to be due to ischemia-induced edema in the internal capsule adjacent to an associated thalamic infarct. Based on angiography, stroke etiology was considered embolic in 83/127 (65%), atherothrombotic in 20/126 (16%), and probably migrainous in 4 (3%) patients. In the remaining 20 patients (16%), the etiology was uncertain. Prognosis of PCA infarcts is usually good.
