Detection of soft tissue hemangioma of the leg by Tc-99m DTPA-HSA blood pool imaging.

A 9-year-old girl had pain and swelling of the left distal thigh for 5 months. Radionuclide angiography of leg arteries was performed using Tc-99m DTPA-HSA. Increased blood pooling was observed in the distal thigh and knee joint area of the left leg 20 minutes after the injection. Open biopsy revealed hemangioma in that area. Blood pool imaging uisng Tc-99m DTPA-HSA is a useful method in the diagnosis of soft tissue hemangioma
