title: Milk of calcium in abdomen.
abstract: A 45-year-old woman had an asymptomatic abnormality on a screening abdominal radiograph. The radiopaque mass in her right upper abdomen was surrounded by numerous "pearls" and resembled an abalone on the supine abdominal radiograph. We advised an additional upright abdominal radiograph, which showed a calcium fluid level. We also clarified the location of the cystic lesion at the right floating kidney, which changed its location between the supine and upright positions. Computed tomography of the abdomen revealed a right renal cyst with a calcium-fluid interface owing to the milk of calcium. The patient was then followed up without additional investigation or the need for intervention.
