[Comprehensive radionuclide diagnosis of hepatic hemangiomas]

Colloid and tumoritropic radiopharmaceuticals are used now for radionuclide diagnosis of tumor hepatic lesions. They allow one to specify the nature of a pathological process of primary hepatoma. The authors have described a case of the diagnosis of hepatic hemangioma using comprehensive radionuclide investigations including scintigraphy with 113mIn-colloid, tumoritropic 75Se-methionine and 113mIn-chloride. A scanogram obtained after the administration of 113mIn-colloid revealed a zone of the lowered accumulation of the radiopharmaceutical in the right liver lobe whose projection coincided with a 75Se-methionine accumulation defect zone indicating the benign nature of the tumor process. The vascular origin of the tumor was determined with the help of 113mIn-chloride which after its i.v. administration labeled transferrin and was circulating in the blood channel. Proceeding from the results of the comprehensive radionuclide study and the clinical findings the diagnosis of hepatic hemangioma was established. Later on it was confirmed at operation and on histological examination of the removed tumor. The proposed scheme of radionuclide study of patients with suspected vascular liver neoplasms can be used both under outpatient conditions and in hospitals fitted out with gamma-topographic equipment.
