Abdominal radiographs of an elderly woman who, in 1954, underwent a barium enema examination because of recurrent abdominal pain.Scattered throughout the abdomen (left image), particularly in the right subdiaphragmatic area (right image), were numerous rounded, calcific densitieswith radiolucent centers (arrows).
Also known as oil granuloma, oleoma, oleogranuloma, paraffinoma, vaselinoma of the peritoneum, and “soap bubble syndrome.” Thispatient said that during a cholecystectomy in 1934, the surgeon had poured mineral oil into her peritoneal cavity to prevent adhesions, a practice thatbegan at the turn of the 20th century. The other lipid agents used for this purpose included olive oil, Vaseline, animal fat, and paraffin. With time,however, it became obvious that these substances acted as irritants rather than lubricants. So by the early 1940s or thereabouts, surgeons abandoned thisprocedure forever.
