A misdiagnosis of choledochal cyst type IB and recommendation to use gold-standard imaging techniques: a case report

A choledochal cyst (CC) is a rare congenital dilation of the biliary ductal system that can cause troublesome complications when left untreated. CC in children classically manifests as a rare triad of the right upper quadrant mass, jaundice, and abdominal pain. Here, we report the case of an eight-year-old boy seen in Paediatric Unit I of Dr Ruth K. M.

Moreover, a hydatid cyst was considered based on ultrasonography (USG) which was later ruled out by the negative serology. A definitive diagnosis of CC was established on magnetic resonance cholangiopancreatography (MRCP). In resource-limited countries, USG is always the first line screening tool for biliary duct abnormalities which in some cases is comprehensibly enough for
