Technetium-99m pertechnetate planar scintigraphy is the procedure of choice to localize ectopic gastric mucosa. However, single photon emission computed tomography/computed tomography (SPECT/CT) provides precise landmarks and scintigraphic findings. We report a case of an adult patient with Meckel's diverticulum involving an atypical location, within the pelvic region, next to the right margin of the urinary bladder. Imaging characteristics supported the diagnosis of either Meckel's or bladder diverticulum. Single photon emission computed tomography /CT was the key method to obtain definite diagnosis, since the low-dose CT revealed the presence of air within the lesion of radiotracer uptake. This finding was suggestive of an outpouching of the bowel wall.
锝-99m 高锝酸盐平面闪烁显像术是定位异位胃黏膜的首选方法。然而，单光子发射计算机断层扫描/计算机断层扫描（SPECT/CT）提供了精确的解剖标志和闪烁显像结果。我们报告了一例成人患者，其 Meckel 憩室位于盆腔区域，紧邻右侧膀胱边缘，位置不典型。影像学特征支持 Meckel 憩室或膀胱憩室的诊断。单光子发射计算机断层扫描/CT 是获得明确诊断的关键方法，因为低剂量 CT 显示放射性示踪剂摄取病变内存在气体。这一发现提示肠壁外膨出。
