Hydatid cyst of the gall bladder-A rare location

Abstract: . A 70 year old female presented with intermittent, dull aching pain in right upper abdomen lasting for four months . Examination revealed hepatomegaly and a hard globular swelling continuous with the right costal margin. Enzyme linked immunosorbant assay for hydatid was positive. Ultrasonography of abdomen revealed a large multicystic lesion in right lobe of the liver and hyperechoic shadows in gall bladder fossa. Contrast enhanced computerized tomography of abdomen documented huge hydatid cyst in right lobe of liver and a thick walled calcified cystic lesion in segment-VI of the liver which was confirmed as a gall bladder at laparotomy. Histopathological examination of the specimen confirmed hydatid cyst of the gall bladder. Larval stage of echinococcus causes hydatid disease. Four species can produce disease in humans. E. granulosus and E.multilocularis cause cystic and alveolar hydatid disease respectively while E. vogeli and E. oligarthus rarely infect humans. Hydatid cyst of the gall bladder is extremely rare and this case report highlights the rarest location of hydatid disease. Key words: Gall bladder, hydatid cyst

Antigen used for inspecting echinococcosis (alveolar hydatid disease)

Abstract: PROBLEM TO BE SOLVED: To provide a method for inspecting echinococcosis (alveolar hydatid disease) having a sufficient sensitivity by using an antigen consisting of an amino acid sequence having a size capable of being synthesized. SOLUTION: This specific amino acid sequence in an Em18 molecule (160 amino acid residues) used conventionally as the antigen for inspecting the alveolar hydatid disease, is found to have an equivalent inspection sensitivity to that of the Em18, and the inspection antigen for the alveolar hydatid disease consisting of the amino acid sequence from 389-391 to 418-428 of the Em18 is used.

Method for diagnosing echinococcus alveolar hydatid disease

Abstract: PROBLEM TO BE SOLVED: To provide an inspecting method which is very useful for simply and quickly diagnosing echinococcus alveolar hydatid disease, and has high specificity, in comparison with conventional methods. SOLUTION: In the method for diagnosing the echinococcus alveolar hydatid disease, a recombined Em18R2 antigen, obtained by removing a C-terminal part from an echinococcus alveolar hydatid Em18 antigen, is brought to react with a subject's serum. This recombined Em18R2 antigen is immobilized on a support and brought to react with the subject's serum, and then a labeled probe is brought to react with it, and its label is detected. This inspection method has the high specificity, in comparison with conventional methods and is very useful for simply and quickly diagnosing the echinococcus alveolar hydatid disease, by combining it with another simple inspecting method.

Liver Transplantation in Alveolar Hydatid Disease

Abstract: Alveolar echinococcosis (AE), or alveolar hydatid disease (AHD), is an uncommon parasitic disease which behaves like a malignant tumor of the liver, producing liver necrosis and invading the biliary tract, main hepatic vessels and surrounding structures. Only 25% of the patients are candidates for radical surgical resection, the only currently available definitive treatment. Ortho-topic liver transplantation (OLT) has been performed for terminal AE since the mid-1980s. This article reviews the specific problems related to OLT in AE. They represent a number of relative contraindications. Invasion of the duodenum and pancreas or the right atrium by the parasitic masses, and cerebral metastases, are absolute contraindication to OLT. Today, OLT can be considered in AE patients with chronic Budd-Chiari syndrome, severe secondary biliary cirrhosis, intractable cholangitis and biliary sepsis, or involvement of both lobes where radical resection is not possible. In our series, which comprises 22 of the 28 European patients transplanted for AE, 1- and 5-year actuarial survival are 78 and 65% respectively.

Alveolar hydatid cyst with lung metastasis: a case report.

Abstract: Alveolar hydatid disease is a serious and often fatal condition caused by infection with the metacestode form of echinococcus multilocularis. Liver involvement is seen in 90% of the cases. The parasite develops within the liver as a rapid invasive pseudomalignant growth and may make distant metastasis. We present the case of a 37 year old woman admitted to our gastroenterology department with obstructive jaundice and then diagnosed as alveolar hydatid cyst with lung metastasis. This case is presented due to its rare prevalence.
