Abstract
BackgroundGastrointestinal bleeding caused by gastrointestinal tract involvement in patients with Klippel–Trenaunay syndrome (KTS) is extremely rare and often overlooked.Case presentationA 9-year-old girl who presented with chronic gastrointestinal bleeding was admitted to our hospital. Laboratory examinations revealed microcytic hypochromic anemia and a positive fecal occult blood test. Computed tomography (CT) of the lower limbs combined with physical examination confirmed KTS. The pelvic CT showed concentric thickening of the sigmoid colon and rectum, with progressive enhancement after the administration of a contrast agent. Colonoscopy demonstrated vascular malformations of the sigmoid colon and rectum. The patient was finally diagnosed with KTS with gastrointestinal tract involvement. The patient improved after receiving conservative treatment.ConclusionsA suspicion of gastrointestinal tract involvement as an etiology for gastrointestinal bleeding should not be overlooked in patients with KTS. Endoscopy and imaging modalities can synergistically help diagnose this condition.
