Appearance of a hepatic hemangioma on prostate immunoscintigraphy value of early images

In this case, the authors describe the appearance of hemangioma, the most common benign tumor of the liver, on early and delayed In-111 CP antibody images. The early immunoscintigraphic images show intense blood pool activity comparable in appearance to labeled RBC imaging, the current procedure of choice for confirming the diagnosis of hemangioma. In combination with disappearance of blood pool activity on the late scintigraphic images, these findings are pathognomonic for hemangioma and sufficiently distinct from the appearance of hepatic metastases on In-111 labeled antibody images to obviate the need for further confirmatory diagnostic studies.
