Abstract

Abstract : Abstract: Iodine activity in the gastrointestinal tract on 123 I or 131 I imaging is usually diffuse and easy to recognize. Hereby we describe 2 cases of intense focal iodine activity in the rectum mimicking sacral metastases that were caused by constipation. Careful history taking and SPECT/CT imaging can be helpful in distinguishing rectal activity from metastatic lesions in such situations.
