Aims and objectives

To describe the radiological semiology in sonography, computed tomography (CT) and magnetic resonance imaging of intra biliary rupture of hydatid cyst.

Methods and materials

It is a desciptive retrospective review carried out from January 2012 to july 2018, in the department of radiology and imaging in Fattouma Bourguiba university hospital, in Monastir. Study included 55 patients, ranging in age from 16 to 72 years, who presented with cholangitis or obstrutive jaundice, with or without history of hepatic hydatid cyct and for whom the hydatid origin had been confirmed. In all cases abdominal ultrasound and abdominal CT were performed. MRI was performed in 22 cases.

Results

Our study included 35 men and 20 women, between 11 and 72 years. Median age was 46.5 years. Five of them had a known medical history of hydatid disease. In the different imaging techniques intrahepatic cystic lesions were shown (localised in the right lobe in 23 cases): hypoechoic on US, hypodense with a non enhanced wall on CT and T1 hypointense, T2 Hyperintense with a characteristic T2 hypointense wall on MRI. Cysts were type 1, 2 and 3 of Gharbi classification in 85 % of...

Conclusion

Intra biliary rupture is athe most frequent complication of hydatid cyst and a potentially life threatening clinical problem leading to cholangitis and sepsis. Radiology findings specially MRI are essential in early preoperative diagnosis of this complication allowing its management.
