CT angiographic evaluation of genetic vascular disease: role in detection, staging, and management of complex vascular pathologic conditions.

CONCLUSION: Although these syndromes share some overlapping features, they have discriminating clinical and imaging features, and knowledge of these features enables the radiologist to aid the referring clinician in making the correct diagnosis.
