Cecal volvulus associated with incomplete situs inversus and splenic dysgenesis

An unusual case of cecal volvulus in a patient with partial situs inversus viscerum is presented. The associated conditions of liver symmetry and splenic dysgenesis were also present. The patient claimed to be a conjoined twin at birth. The association of twinning and situs inversus is discussed as are some of the lesser appreciated physical findings associated with the phenomenon. Treatment of the cecal volvulus in this case required consideration of a number of operative alternatives.
