“…Hydatid cysts in the liver exert pressure on the surrounding parenchyma and in some cases, the cysts eventually leak into small bile ducts or perforate into larger ones; some sort of communication can be found in 40%–90% of the cases. 14,15 This could result in biliary obstruction, presenting as obstructive jaundice and cholangitis in 5%–17% cases. 16…”

“…17 ERC can also demonstrate communication, if any, between the cystic cavity and the biliary tree. 15 In the recent past, the role of magnetic resonance cholangiography in the diagnosis of biliary ascariasis has been described. 18,19 However, sonography continues to be an ideal modality for detecting ascarids in the bile ducts and monitoring their movements.…”

Cases of biliary ascariasis and hydatid cysts in liver and elsewhere are common in endemic areas and are routinely encountered in surgical outpatient departments. We describe the diagnosis and management of a unique case, who presented with manifestations of biliary ascariasis, but on further investigation was found to harbor ascarids as well as ruptured hydatids in his biliary passages. To our knowledge, this is the first reported case of simultaneous parasitization of common bile duct by ascarid and hydatid forms, resulting in obstruction of the biliary system. This report highlights the diversity of presentation and challenges in the management of such cases, when encountered in practice.

Sonographic and cholangiographic appearances of confirmed intrabiliary rupture of a hepatic hydatid cyst were studied in 15 cases. Sonographic findings included liver cyst in all cases; nonshadowing echogenic structures in the dilated biliary tree representing hydatid material, such as fragmented membranes, sand, matrix, and daughter vesicles, in eight cases; and loss of continuity of the cyst wall adjacent to the bile duct representing the site of communication in seven cases. Cholangiographic findings were as follows: filling defects of varying size and shapes in the dilated biliary tree in 13 cases, and changing shape and position of these filling defects in three of them; and leakage of contrast medium into the cyst cavity in 12 cases. Intrabiliary rupture of hepatic hydatid cyst was suggested by sonography in 10 cases (66.7%) and at cholangiography in 13 cases (86.6%). We conclude that a joint application of sonography and endoscopic cholangiography is mandatory for proper preoperative evaluation of this disorder.

Complications of hepatic hydatid cysts: Ultrasound, computed tomography, and magnetic resonance diagnosis

A total of 179 hepatic hydatid cysts (HHCs) were studied by ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI). The diagnosis of HHC complications was established by US and CT, which permitted a distinction between intact cysts and those presenting with contained rupture, as demonstrated by a collapsed endocyst or a globally echogenic appearance. The diagnosis of HHC perforation into the main biliary tree was made by detection of a discontinuity in the cyst wall and/or the presence of hydatid material within the biliary system. Similarly, direct HHC rupture into different thoracoabdominal spaces was diagnosed by demonstrating cyst wall discontinuity and the presence of hydatid material within these spaces. Ruptured and infected cysts were difficult to distinguish from ruptured cysts with sterile content. The role of MRI is yet to be defined in the assessment of HHC complications.

Endoscopic Retrograde Cholangiography (E.R.C.P.) and Complicated Hepatic Hydatid Cyst in the Biliary Tract

Abstract: A complicated hepatic hydatid cyst in the biliary tract is a cause of cholestasis that we must consider in an endemic geographical area. ERCP is a valuable technique for its diagnosis. In our experience, this eventuality represents 2.6% of the indications for ERCP in biliary diseases.
