Among the known complications of appendiceal mucocele, it is known to be unusual for the appendiceal mucocele to be a cause of ureteral obstruction. Only a few reports have been published in the English literature. We describe a case of right hydronephroureterosis secondary to appendiceal mucocele diagnosed with multidetector-row CT.
