I’ve only seen this a few times, but each case presented with a very ill child with an acute obstruction. Check out the linked post from @PedEMMorsels / Sean Fox.

Per Sean key X-ray findings reveal that the “cecum may be dilated and located in the left mid-abdomen or left upper quadrant.” In general the X-ray is abnormal. Also, interestingly chronic constipation can be a cause.
