The condition was inherited as an autosomal dominant trait with variable expressivity. Forty\u2010three relatives were examined prospectively by cranial computed tomography (CCT) and lesions were found in 15; 7 were followed prospectively with CCT scans for 5 years. Angiography in 5 of these cases failed to demonstrate the lesion. In 3 patients with previously normal CCT scans a change in blood volume or membrane permeability allowed visualization of the lesion on contrast scans. In 2 individuals, both parents of affected children, a normal CCT scan was found. This emphasizes the limitations of CCT in detecting this disorder. Biochemical and red blood cell immunological genetic linkage studies were done in 36 persons. No linkage was found with any of the markers. The natural history of this disorder, characterized by marked clinical and radiographic variation in site of lesion, and the timing and severity of intracranial hemorrhage, make it a useful model for investigating contributing factors and consequences of intracranial hemorrhage in general. For atrisk and affected patients early and sequential CCTs are necessary. Familial cavernous angioma should be included in the differential diagnosis of all young persons presenting with cerebrovascular impairment, seizures, intracranial calcifications or hemorrhage.<\/jats:p>","DOI":"10.1002\/ajmg.1320110205","type":"journal-article","created":{"date-parts":[[2005,6,11]],"date-time":"2005-06-11T18:38:20Z","timestamp":1118515100000},"page":"147-160","source":"Crossref","is-referenced-by-count":136,"title":["Familial cavernous angiomas: Natural history and genetic study over a 5\u2010year period"],"prefix":"10.1002","volume":"11","author":[{"given":"L.
