Ruptured Posterior Communicating Artery Aneurysm Associated with Aarskog Syndrome.

A 44-year-old male with Aarskog syndrome (AS) presented with subarachnoid hemorrhage secondary to ruptured posterior communicating artery aneurysm. AS, also known as faciogenital dysplasia, is an X-linked, autosomal dominant or autosomal recessive congenital developmental disorder. This syndrome is characterized by short stature in association with a variety of multiple anomalies in musculoskeletal, neurological, and urogenital systems. Cerebrovascular abnormalities such as anomalous cerebral venous drainage, dysplastic internal carotid artery, and basilar artery malformation have been reported to be associated with AS. To our knowledge this represents the first case of a ruptured intracranial aneurysm in a patient with AS.
