title: The preauricular sulcus: its radiologic evidence and prevalence.
abstract: The preauricular sulcus is a groove frequently seen on the iliac bone, adjacent and parallel to the inferior surface of the sacroiliac joint. It has been described as a characteristic of the female pelvis. A total of 3200 pelvic radiographs (1508 male and 1692 female) were examined and in 393 female (about 23%) the preauricular sulcus was encountered. None was seen in male radiographs.
