The Mickey Mouse Sign: A Novel Sign for a Compliant and Underactive Bladder Syndrome.

This article represents a unique CT-based sign called the Mickey Mouse sign in a diabetic female who presented with abdominal distension and mixed urinary symptoms. The CT scan showed that the bladder was massively dilated but compliant without impacting the upper urinary tract. The subtle clinical presentation and the impressive CT scan findings encouraged us to report this case as underactive bladder syndrome (UAB) is underreported and underinvestigated. Furthermore, the management and clinical course of UAB in such cases remain controversial.
