How is it diagnosed?
Usually, cysts are detected by ultrasound scanning or computed tomography, performed for other reasons. Diagnostic confirmation is usually obtained by searching for specific antibodies (anti-echinococcal antibodies), using a simple blood test.
Cysts that have been present for a long time can undergo calcification and thus be visible even on a simple X-ray. The disease, although rare, can spread to the lungs and to the brain.
