of choledocholithiasis (Figure four). Ascarids
typically lie parallel to the lengthy axis of the bile duct. (1,two)
Endoscopic retrograde cholangiopancreatography, a fairly
invasive approach, can be utilized to image biliary ascariasis. On transverse T2-weighted photos,
the worm is observed as "double bull's-eye" or
"eye-glass" look formed by the coiled portion of the
Ascaris worm (2 higher-density rings in the CBD). Hospital, New Delhi, India.

MRI and MRCP confirmed multiple intrahepatic abscesses, bilobar
intrahepatic biliary dilation, and a dilated proximal CBD (Figures three and
four). A linear tubular structure with central hyperintensity was noticed in
the proximal CBD. Other abdominal viscera had been normal, and no
ascites or enlarged lymph nodes have been detected.

The hepatobiliary tree is 1 of the most popular ectopic web sites for
ascariasis mainly because of its effortless accessibility, and this organism is a
known cause of biliary tract disease, specially biliary colic, acute
cholecystitis, cholangitis, and acute pancreatitis. Other biliary parasites are much smaller sized than Ascaris
lumbricoides and, consequently, not element of the differential diagnosis in
this case. MRI and
MRCP, despite the fact that not the main imaging modalities for hepatobiliary
ascariasis, can reveal the extent of disease in the biliary tree, the
status of the intrahepatic biliary radicals, and any other related
lesions (such as cholangitic abscesses) to far better advantage and with
a lot more clarity than can other modalities.

echogenic structures that suggested the presence of worms in the
gallbladder as well (Figure 1). The intrahepatic biliary ducts
and the prevalent bile duct (CBD) had been dilated with intraluminal echogenic
linear tubular structures, which were suggestive of roundworms (Figure
two). Other appearances described in the literature
are the "strip sign," "inner-tube sign," and
"bull's-eye" look. (three)
IMAGING FINDINGS
(1.) Anand R, Narula MK, Gupta A, Vig K. Sonography is a nicely-established
imaging modality for the diagnosis of hepatobiliary ascariasis. Migration of worms into
the biliary tree is a properly-identified complication, which might outcome in
biliary colic, cholecystitis, cholangitis, intrahepatic abscesses, or
pancreatitis. The diagnosis is established by means of microscopic
identification of A lumbricoides eggs in fecal samples.

Biliary ascariasis is second only to cholelithiasis as a trigger of
acute biliary symptoms worldwide. They may perhaps be
coiled and, if a number of, might fully fill the bile duct, which
produces either the "spaghetti sign," or, if they are incredibly
densely packed in the bile ducts, may perhaps seem amorphous and manifest as
hyperechoic pseudotumors. (two)
