Appendicitis in an obturator hernia.

We present a case of a 79-year-old female with a history of pain at the right groin for 9 days. Computer tomography of the pelvis showed herniation of the appendix through the obturator canal with a huge abscess surrounding the right hip joint. Laparotomy was performed and histopathology confirmed a perforated necrotic tip of the herniated appendix.

Paget's disease with vanishing bone pattern and spinal fusion.

We present a rare case of Paget's disease involving the spine and pelvis, with unusual imaging features, including severe bony expansion and fatty infiltration, resulting in a "vanishing bone" appearance. Other rare imaging features are the presence of spinal and sacroiliac ankylosis.
