A rare presentation of Klippel–Trenaunay syndrome with bilateral lower limbs

Abstract

Klippel–Trenaunay syndrome (KTS) is a vascular lymphatic malformation underlying with bony and soft tissue hypertrophy. It is a rare condition presenting in 1 out of 10 000 people. The growth disturbance due to KTS is more commonly unilateral (85%) than bilateral (12.5%), and most rarely crossed-bilateral (2.5%). A man in his 40s presented to our hospital with a com-plaint of lower limb discomfort. Radiograph, ultrasonography, computed tomography venography, magnetic resonance (and venography) showed various radiological findings characteristic for KTS. Because the patient was symptomatic, he under-went stripping of bilateral great saphenous vein and varicectomy of bilateral legs. The surgical procedures were undertaken successfully, and there has been no recurrent symptom for about 2 years and a half. In this study, we report a very rare case of bilateral KTS diagnosed by radiological and clinical manifestations with some literature review.
