“…The sonographic data obtained in our case similar to those reported in the literature; of all the signs described, in our case only edema of the gallbladder wall (over 4 -m m thick) was not present, as described by others [4,5,8,11,12]. We believe therefore that the US finding of a ribbonlike image, with the so-called tube sign (hyperechogenicity without acoustic shadow; This is also true when a positive smear examination of stools is lacking, because an infection could be due to a male worm, which does not leave eggs in the bowel [2].…”

Ascariasis is the most common helminthic infection, but the invasion of worms into the gallbladder is quite rare. This report illustrates the ultrasonographic findings in gallbladder ascariasis of a typical echogenic structure which exhibits nondirectional movements and contains a central anechoic tube, along the long axis of the gallbladder. The role of ultrasound as a diagnostic tool and in the follow-up treatment is stressed.

“…into the biliary tree is not uncommon and is considered to be a frequent complication of intestinal ascariasis [4]. Clinically, obstructive jaundice in children is uncommon, and its most frequent causes are hepatic tumors, ascariasis, and adenopathy [4,8]. In our patient, jaundice was the main presentation, which is considered to be due to the impact of the worm in the distal CBD.…”

Biliary ascariasis: CT, MR cholangiopancreatography, and navigator endoscopic appearance—report of a case of acute biliary obstruction

A case of acute common bile duct obstruction caused by a roundworm in a 6-year-old girl is reported. Computed tomography (CT) and magnetic resonance imaging (MRI) showed "bull's-eye" and "eye-glass" appearances of the ascaris in the common bile duct. On reformation of the transverse CT and coronal MR images, the tubular Ascaris was better depicted. MRI and navigator endoscopic demonstrations of the common bile duct ascaris have not been described previously in the literature. These CT and MRI findings may be helpful in the diagnosis of Ascaris.

“…Many appearances of biliary ascariasis have been described [10,11] like inner tube sign, stripe sign and spaghetti sign. Real time sonography may also demonstrate the mobility of these worms within the biliary passages.…”

In India, ascariasis is highly endemic, especially in paediatric population. Ascaris usually lives in the duodenum but wanders through the orifices, ducts and cavities to reach common bile duct, liver and pancreas, thereby leading to a plethora of clinical presentations. Fulminant hepatobiliary infestation is rare and infrequently reported. We present a case of a child who had overwhelming infestation of the small bowel, extra-hepatic biliary system and liver which was managed conservatively.Ascariasis is the most common helminthic infection in the world and is seen mostly in the developing countries of Asia. We report a case of heavy worm infestation in a 2-year-old child who presented with worms in small bowel, common bile duct and liver with abscesses. He was managed conservatively and recovered well without any sequalae.
