Presentation
Progressive yellowish discolouration of the eyes, urine, and skin all over the body.
Patient Data
On MRCP sequence:
hypoplastic gallbladder with an average length measuring 1.2 x 0.8 cm (normal length >19 mm) with hepatomegaly
non-visualization of the common hepatic duct, common bile duct, and intrahepatic duct
with increased periportal echogenicity is noted. overall features consistent with congenital biliary atresia (type 3 Kasai)
Case Discussion
Biliary atresia is a congenital anomaly in which there is a variable degree of atresia of the extrahepatic biliary ducts. with an incidence of approximately 1:15000 having male prediction.
A baby with congenital atresia is normal at birth, with symptoms starting to develop after 2 weeks to 2 months of age. Less than 10% of cases present with syndromic conditions such as polysplenia, interrupted IVC, etc.
In this case, the gall bladder is hypoplastic with a length of less than 19 mm, with non-visualization of the common hepatic duct and common bile duct, and increased periportal signal intensity along with hepatomegaly. Overall features are consistent with biliary atresia Kasai type 3.
