چکیده

Autosomal dominant polycystic kidney disease is genetically heterogenous, with at least two chromosomal loci accounting for the disease. When the mutation is located on chromosome 16 (PKD1), extra-renal manifestations such as the rupture of intracranial aneurysms are well known. In the case of localization on chromosome 4 (PKD2), in which the renal disease runs a milder course, not much is known about the incidence of extrarenal manifestations. A PKD2 family is reported in which two members had subarachnoidal bleeding due to intracranial aneurysms; there was strong clinical evidence of subarachnoidal bleeding in a third family member. This indicates that the familial clustering of intracranial aneurysms may also occur in PKD2 families. Because of the considerable mortality and morbidity of intracranial aneurysms, screening with magnetic resonance angiography in PKD2 patients with a positive family history of intracranial aneurysms is recommended.

Familial intracranial aneurysms.

BACKGROUND We set out to determine the prevalence of incidental intracranial aneurysms in first-degree relatives aged 30 years or more of people with intracranial aneurysms, and to see if polycystic kidney disease contributes to the aggregation of familial intracranial aneurysms. METHODS 91 families with two or more affected members had previously been identified from a 14 year series of 1150...

On the role of screening for intracranial aneurysms in autosomal dominant polycystic kidney disease.

Screening patients with autosomal dominant polycystic kidney disease (ADPKD) for asymptomatic intracranial aneurysms has been proposed as a method of reducing the morbidity and mortality associated with aneurysm rupture. However, recent studies have shown lower spontaneous rupture rates of small aneurysms and higher risks of significant complications with interventions than previously reported....

Extracranial Aneurysms in 2 Patients with Autosomal Recessive Polycystic Kidney Disease

Unlike autosomal dominant polycystic kidney disease (ADPKD), autosomal recessive polycystic kidney disease (ARPKD) is not generally known to be associated with vascular abnormalities. Only 4 cases of ARPKD patients with intracranial aneurysms have been reported previously. We present 2 ARPKD patients with extracranial vascular abnormalities: a young man with infrarenal aortic and iliac artery a...
