Reveals inguinal bladder hernia in a male with prostate cancer, indicating diagnostic challenges in SPECT imaging.
An 89-year-old male with newly diagnosed prostate cancer underwent routine bone single photon emission computed tomography (SPECT) imaging. The scan revealed increased technetium-99m methylene diphosphonate ( 99 Tcm-MDP) uptake in the anterior segment of the left 9th rib, the 8th thoracic vertebra, and the right pubic region, raising suspicion of widespread osseous metastases. Previous chest computed tomography (CT) showed definite fractures of the left 9th rib and 8th thoracic vertebrae, so we suspected that the MDP concentration in the right pubic region might be due to other causes as well. Subsequent SPECT/CT fusion imaging diagnosed the MDP-concentrating foci at this site as an inguinal bladder hernia.
