Extensive venolymphatic involvement in infantile Klippel-Trenaunay syndrome: A rare case from Ethiopia

Klippel-Trenaunay syndrome (KTS) is a rare congenital disorder characterized by a triad of clinical features: capillary malformations, venous varicosities, and hypertrophy of soft or bony tissues. This case report presents a 1-year-old infant diagnosed with KTS, exhibiting multifocal pelvic, gluteal, and thigh macrocystic lymphatic malformations alongside significant limb overgrowth. The diagnosis was confirmed through clinical evaluation and advanced imaging techniques, including Doppler ultrasound and CT angiography. KTS poses unique challenges in diagnosis and management, necessitating a multidisciplinary approach to address potential complications such as deep vein thrombosis and chronic pain. This case underscores the importance of early diagnosis and ongoing monitoring in improving patient outcomes and highlights the need for increased awareness of the multiple imaging spectra of KTS among healthcare professionals.
