Portal biliopathy; multidetector CT (MDCT) imaging features

Aim of the work

The aim of this retrospective study is to highlight the MDCT features of portal biliopathy (PB).

Patients

This study included 32 patients with extra-hepatic portal vein obstruction (EHPVO) and biliary dilatation. Their age ranged from 27 to 63?years, including 21 males and 11 females.

Methods

The included patients had records of complete clinical examination and laboratory data, including bilirubin levels. All patients were examined by multiphase MDCT study with good portal phase.

Results

Extra-hepatic biliary dilatation without intra-hepatic dilatation seen in 5 patients (type I), intra-hepatic dilatation without extra-hepatic dilatation seen in 12 (type II) patients, unilateral intra-hepatic predominant with extra-hepatic dilatation (type IIIA) seen in 7 patients (4 right sided predominance and 3 left sided predominance). Both extra and bilateral intra-hepatic dilatation in 8 patients (type IIIB).

Conclusion

MDCT is an excellent technique for the diagnosis of portal biliopathy reducing errors in diagnosis.
