Volvulus of the spleen.

Volvulus of the spleen in absence of malarious splenomegaly is rare. Most reported instances occur in young and middle-aged women and are related to a congenital abnormality of the mesogastrium, pregnancy, and multiparity. In this reported case of splenic volvulus in a young, multiparous woman, posterior mesogastrium malformation was the cause. Certain preoperative findings could suggest this infrequent diagnosis in future cases.
