COMPUTED TOMOGRAPHY IMAGING PRESENTATION IN THORACIC HYDATID CYSTS

Hydatid cysts are widespread zoonosis that originate from the larval embodiment of Echinococcusand can be frequently found in lung and liver parenchyma, addition, they emerge various atypical locationsin thoracic cavity such as mediastinum, its vascular compounds heart, interlobar fissures, thepleural pericardial space, well structures chest wall diaphragm. Computed tomographyas one most utilized instruments radiology imaging has a crucial role diagnosis hydatid cysts,depiction their exact size location, estimation impending complications.The aim this pictorial review is to offer full scale understanding recurrent findings thoracichydatid disease display some rare, extra parenchymal involvement summary complicationsand differential diagnosis.We did an depth analysis 55 CT scans patients with North Macedonia andall underwent contrast enhanced according appropriate diagnostic protocol on 16- sliceSomatom GO computed tomograph (Siemens Healthineers, USA).Hydatid all were divided by location appearance two categories, uncomplicatedparenchymal parenchymal, complicated or ruptured cysts.Uncomplicated presented circumscribed, low attenuating, homogenouslesions smooth walls varying thickness, whereas could categorizedin forms, contained complete rupture. The frequent air crescent sign,waterlily sign dry cyst sign. Uncommon cysts’ locations mediastinum,pericardium diaphragm.Computed tomography plays important common aids theevaluation rare cases.
