Occult gastric bleeding demonstrated by bone scan and Tc-99m-DTPA renal scan.
A patient is described who had coagulopathy and clinically intermittent gastrointestinal bleeding. The bleeding site was clearly shown on renal and bone imaging performed at a time when the patient was considered clinically to have stopped bleeding. A bleeding gastric ulcer was subsequently demonstrated by radionuclide and contrast angiography, and at surgery.
