“…Multiple Ascaris Lumbricoides round worms can result in intestinal obstruction, or even cause volvulus with consequent necrosis of the involved bowel segment [ 8 ]. Magnetic resonance cholangio-pancreatography (MRCP) also has a role in the diagnosis of hepatobiliary ascariasis [ 9 ], and though other parasites can be involved in the biliary system [ 10 ], ultrasound with all its typical imaging features has a definite role in the diagnosis of hepato-pancreatico-biliary and intestinal ascariasis.…”

Despite advancement in the diagnosis and treatment of intestinal helminthiasis, ascariasis remains the most common cause of helminthic infections in the developing countries. Ultrasound offers a rapid, safe, and noninvasive approach to the diagnosis of intestinal ascariasis. Ultrasound is also the modality of choice for diagnosis of hepatobiliary ascariasis, which is relatively rare and is due to migration of intestinal worms through the papilla of Vater. We present an imaging spectrum of hepato-pancreatico-biliary and intestinal ascariasis.Main messages• Ascariasis refer to infestation by the round worm ascaris lumbricoides.• Ascaris eggs are excreted in faeces and are infective to humans.• Eggs hatch to larva, travel to the lungs and mature to adult worms.• Intestinal obstruction can be caused by multiple ascariasis forming bag of worms.

“…Sometimes the USS is inconclusive, such as in this case, therefore MRCP is a useful additional imaging modality. It shows intraductal worms as linear hypo intense filling defects [ 4 , 9 ], which was seen on this patient’s scan.…”

Biliary ascariasis is a tropical infectious disease, endemic in regions such as the Far East, Indian subcontinent and parts of the Middle East. The responsible organism is the Ascaris lumbricoides worm. This case study presents a 54-year-old British Caucasian female patient, admitted with a 1-week history of generalized abdominal pain. Ultrasound scan of the abdomen showed a collapsed and abnormal image of the gallbladder. Further imaging for better visualization by magnetic resonance cholangiography showed a 6 cm linear structure in the gallbladder. The morphology was characteristic of gallbladder ascariasis. Detailed history revealed that 6 months ago she had travelled to Turkey. Stool cultures confirmed the presence of ascaris eggs. She was treated conservatively with a 500 mg stat dose of Mebendazole. She was followed up in 6 weeks showing complete resolution of her symptoms.

“…Magnetic resonance cholangiopancreatography (MRCP) also has a role in the diagnosis of hepatobiliary ascariasis. MRCP may detect adult worms in bile or pancreatic ducts, yet it is costly, time consuming, and not easily available [99]. On MRCP imaging, Ascaris worms demonstrate a characteristic 3-parallel-lines appearance.…”

Ascariasis is not widespread in Europe, and the knowledge on how to diagnose and treat the disease is limited to some specialists. On the other hand, clinicians are facing an increasing number of immigrants from high-prevalence countries and are, therefore, challenged to update in this field of infectious diseases. Here we present current knowledge on this infection in 2 parts. The first part discusses clinical features and hot topics in ascariasis, and the second part presents imaging features of ascariasis as a pictorial essay.

Biliary ascariasis on magnetic resonance cholangiopancreatography

Abstract: A 17-year-old girl presented with features of biliary obstruction. Magnetic resonance cholangi-pancreatography revealed typical linear signals in common bile duct, which appears like Ascaris lumbricoides. The diagnosis was confirmed by endoscopic removal of the worm.
