Iliac fossa - Definition

Ask a question


The iliac fossa is a part of the abdomen that is medically divided into a square containing 3 rows and 3 columns. The iliac fossae are located at the bottom of the square, on each side. The precise location of abdominal pain can enable the identification of different origins. The right iliac fossa can be painful in disorders of the right ovary, a right inguinal hernia, or appendicitis. The left iliac fossa, rather, indicates a disorder in the left ovary or in the colon like constipation or inflammation of diverticula.
