Klippel-Trénaunay syndrome (KTS) evaluated with bone and labeled RBC scintigraphy

This is a case of a 4-year-old female child with gross left lower extremity deformity detected at birth, including a giant cutaneous hemangioma from flank to foot. She was found to have no other associated abnormalities and was diagnosed with Klippel-Trénaunay syndrome. This is a rare entity and literature regarding use of radionuclide imaging techniques to evaluate this is scarce. We present here bone and red cell scans performed to evaluate whether there was osseous involvement or only soft tissue disease, which showed classic signs of this condition. Patient photographs also show the syndrome's typical appearance.
