“…GB ascariasis is a very rare presentation. Sometimes the worm enters into the common bile duct, passing through the papilla of Vater present in the second part of duodenum and then into the gallbladder lumen through the cystic duct [5].…”

“…The live worm might present as tubular, linear, parallel, non-shadowing echogenic lines inside the gallbladder lumen. On BMUS, coiling, zigzag and non-directional movements features could be visualized [5]. Common typical ultrasound features of ascariasis have been described as linear or curvilinear thick, echogenic, non-shadowing structures with central anechoic longitudinal tubes [1,4,9].…”

“…Most patients with A. lumbricoides or A. suum infection are asymptomatic but need anthelminthic treatment [1]. Since worm invasion into the gallbladder (GB) is less common because of anatomical features, GB ascariasis is quite rare, constituting 2.1% of hepatobiliary ascariasis [2][3][4][5][6][7].…”

Differential diagnosis of gallbladder ascariasis debris: the added value of contrast enhanced ultrasound with high frequency transducer

Ascariasis debris of the gallbladder is a very rare incidental or symptomatic presentation. Ascaris debris has a pseudotumorous appearance and may be confused with neoplasia. The aim of the current retrospective study is to investigate the value of contrast enhanced ultrasound (CEUS) for the differential diagnosis of ascariasis debris and neoplasia of the gallbladder.Material and methods: Conventional B-mode ultrasound (BMUS) and CEUS were performed for solitary echo-rich gallbladder lesions. Analysis of the CEUS enhancement pattern of the lesions was conducted according to the current EFSUMB guidelines. Two radiologists assessed the CEUS enhancement patterns in consensus. The final gold standard was surgery with histological examination or imaging follow-up.Results: A total of 9 patients with final diagnoses of gallbladder ascariasis debris were included. As a control group 26 solitary hyperechoic gallbladder lesions without shadowing were included as a control group. The typical zigzag morphology with multiple echogenic parallel lines without shadow were detected inside the lumen of the gallbladder in 6 patients. After injection of 2.4 ml ultrasound contrast agents, all hyperechoic gallbladder ascariasis debris lesions showed no enhancement. All patients in the control group with similar BMUS morphology showed contrast enhancement.Conclusions: Real time visualization of contrast enhancement without radiation exposure is one of the main advantages of CEUS over other diagnostic modalities to differentiate ascariasis debris in the gallbladder from enhancing neoplasia. Thus, surgery and other interventions and their complications could be avoided.

“…Several reports exist about the successful medical treatment of gallbladder ascariasis. 5,8,10,[12][13][14]18,19 Sometimes surgery 4,6,8,10,16 or the endoscopic procedures 7,8,10 such as endoscopic retrograde cholangiopancreatographic examination are required. Albendazole and mebendazole are first-line agents for the treatment of ascariasis.…”

An alien in the gallbladder. A rare case of biliary ascariasis in an Italian emergency department

et al. 2016

Ascariasis is a common infection in many developing countries. The prevalence of ascariasis is related to poverty, poor hygienic and sanitary conditions. The adult form of Ascaris lumbricoides usually resides in the human intestinal lumen (more frequently in the jejunum and middle ileum) and does not cause symptoms. However, it can occasionally cause severe complications such as intestinal obstruction or perforation peritonitis. Its migration into the biliary tract is not uncommon but gallbladder involvement is very rare. Abdominal ultrasonography is essential to detect the presence of this parasite. In this article, we describe the radiologic findings, clinical manifestations and successful medical treatment of a patient with gallbladder ascariasis diagnosed in an emergency setting.

“…P arasitosis by the nematode Ascaris lumbricoides is a very common condition, but the presence of the worm in the gallbladder is unusual 1 . Found especially in endemic places and areas of poor sanitation, just like in some regions of Brazil, the worm is transmitted through fecal-oral route 2 .…”

A infecção parasitária pelo Ascaris lumbricoides representa um acometimento comum no Brasil e em outras regionalidades subdesenvolvidas. A localização do verme em vesícula biliar é rara e quando há presença de quadro clínico importante, essa hipótese deve ser levantada como diagnóstico diferencial frente a outras doenças da árvore biliar. Relatamos o caso de paciente de 65 anos admitido em emergência devido à pancreatite por etiologia de áscaris em vesícula biliar, o qual, posteriormente, evoluiu para quadro alarmante de disfunção de múltiplos órgãos.
