A COMPARATIVE STUDY OF SENSITIVITY OF SEROLOGIC TESTS AND IMAGING METHODS IN DIAGNOSIS OF HYDATID CYST

Background & Aims: Hydatid cyst is zoonosis disorder and is one of the global health problems, especially in the developing countries. There are different diagnostic methods for the hydatid cyst. In this study, sensitivity of serologic and imaging methods has been studied comparatively. Materials & Methods: This study carried out cross-sectionally on the 45 patients with hydatid cyst. For all patients serologic tests (1HA, ELISA) were done and results of these tests with imaging findings were studied. Results: from 45 patients in this study, in the 16 patients with surgically established hydatid cyst, sensitivity of IHA and ELISA in the diagnosis of hydatid cyst of liver and lung was 85.7% and 55.5% respectively which showed no meaningful statistical difference(p-value=0.11). Sensitivity of imaging methods in the diagnosis of surgically established hydatid cyst was estimated 100% for hydatid cyst of lung and 85.7% for hydatid cyst of liver which showed meaningful statistical difference in comparison with serologic methods(p-value=0.01). Discussion: This study showed sensitivity of imaging methods in the diagnosis of hydatid cyst is greater than serologic tests. So, it seems that imaging findings could be more useful in the diagnosis of hydatid cyst.
