[A woman with floating spheres in her abdomen]. / Een vrouw met drijvende bolletjes in haar buik.

A 55-year-old postmenopausal woman presented with acute abdominal pain. Ultrasound and MRI revealed a large, unilocular, cystic abdominal mass, with remarkable floating spheres. Histopathology showed a dermoid cyst. This is a benign ovarian neoplasm, which can contain elements of all three germ layers: primarily hair, teeth, skin or sebaceous tissue.
