title: Congenital absence of internal carotid artery associated with hypogonadotropic hypogonadism--a case report.
abstract: Congenital absence of internal carotid artery is a relatively rare disorder. It may be an isolated entity or combined with other organ or system anomalies. Investigations of a 19-year-old male patient with hypogonadotropic hypogonadism and hypothyroidism suffering from intracerebral and subarachnoid hemorrhages showed absence of the left internal carotid artery. The association of endocrinologic disorders and congenital absence of internal carotid artery is discussed with the pertinent literature. In conclusion, association of the absence of internal carotid artery and hypogonadism is extremely rare. Patients with absence of internal carotid artery may also have intracerebral and subarachnoid hemorrhages and should be followed up closely.
