The gold standard for diagnosis of echinococcal cyst is
Correct Answer: ELISA
Description: USG is the cornerstone for diagnosis and staging of cystic echinococcus (especially liver).MRI is capable of reproducing ultrasound features of cystic echinococcal and is preferred over CT where USG cannot be used because of a difficult location.Serological tests are commonly employed to supplement the radiological data in the diagnosis of hydatid cyst. The current gold standard serology test for echinococcosis detects IgG antibodies to hydatid cyst fluid-derived native or recombinant antigen B subunits. This is performed using ELISA or immunoblot formats Classification of hydatid cyst:GharbiWHOUS characteristicsType 1CE 1Unilocular cyst + wall + internal echogenicitiesType 2CE 3Detached membraneType 3CE 2Multivesicular, multiseptated cyst, daughter cystsType 4CE 4Heterogeneous cyst, no daughter vesiclesType 5CE 5Cyst with a wall calcification(Ref: Grainger and Allison&;s diagnostic radiology 6th edition, 770)
