According to abdominal computerized tomography, a foreign object had been placed through the anus right down post-laterally from the left upper anterior on the coronal plane, and the object continued to the anorectic junction and was partially distal in the rectum (Fig. 2). This erosion reached 80-90% of the thickness of the bone, particularly on the ischio-pubic junction region (Fig. 2).
