title: Not-to-tap cystic lesions: spectrum of hydatid disease.
abstract: Hydatid disease (HD) may occur almost anywhere in the body. Despite their characteristic radiologic manifestations at times, they may enlarge and produce bizarre imaging features which make diagnosis challenging, particularly for those radiologists working in areas of low incidence. Plain radiography, ultrasonography, computed tomography, and magnetic resonance imaging may demonstrate some of the typical imaging manifestations of HD as well as its exact extension. On the other hand, particular caution is required before any kind of interventions to be done in that biopsy or aspiration of such lesions may cause devastating consequences, in particular anaphylactic shock. Hence, being familiar with various radiologic features of HD is essential in improving diagnostic accuracy and also preventing adverse reactions in these patients. The purpose of this pictorial review is to illustrate the different radiological features of HD in various organs.
