Abstract:
RBC scintigraphy has shown to be a sensitive imaging technique for detecting gastrointestinal bleed. There may be a time interval between the initiation of bleed and appearance of symptoms. This study can help in localizing the site of active bleed; though, false positive results may be seen. A patient of chronic liver disease presented with dark stools and falling hemoglobin who after initial management, showed focal tracer uptake in the pelvis on 99mTc-labelled RBC scintigraphy planar imaging suggesting gastrointestinal bleed. However, SPECT/CT accurately localized the tracer activity in a previously undiagnosed urinary bladder hernia in the inguinal canal and scrotum.
