Soft tissue shadows are commonly seen on pelvic radiographs, and radiographers may overlook or are unaware that these shadows could be artefacts. In a case study, shadow of a penis superimposed with the fracture lines at pubic ramus and it was questioned whether a fracture of ramus ischio-pubis is present. Further radiographic views were performed to demonstrate the fractures without any artefact. There are other possible pelvic artefacts that may be seen and neglected on pelvic radiographs, thus it may lead to misdiagnosis of pelvic fracture. This essay should be served as a reminder for radiographers to recognize artefacts and differentiate it from pathology.
