Pedicle torsion is the most common complication of ectopic spleen. The observation we bring was the case of a 20 year old lady admitted to the emergency room with an acute surgical abdomen picture evolving for about two years. Clinical examination revealed generalized abdominal pain and a mass in the right iliac fossa. The torsion of the spleen was suspected by the clinic, the abdomino-pelvic ultrasound and confirmed during an exploratory laparotomy. Intraoperatively the spleen was necrotic on a long twisted pedicle indicating a splenectomy.
