Presentation
Chronic cough with recent right-sided chest pain.
Patient Data
A 70 × 58 mm thick-walled cystic lesion with internal air-fluid level is noted in the right lower lobe, accompanied by mild adjacent lung collapse and ipsilateral pleural effusion. A few small nodules less than 8mm are seen in the vicinity of the aforementioned complicated cyst.
In addition, a few prominent lymph nodes are observed in the right lung hilum.
There are also two 105 × 90 mm and 80 × 70 mm thick-walled cystic lesions with fine internal septations and without enhancing solid components in the liver. The left lobe lesion is causing upstream bile duct dilatation.
Case Discussion
The findings on CT images are typical for pulmonary and hepatic hydatid cysts (serologically proven). The pulmonary hydatid cyst shows an air-fluid level which indicates cyst rupture and airway communication.
