Correct answer to Q1 is: Right sided opacity, right sided hydropneumothorax and elevation of the right diaphragm

Correct answer to Q2 is: Hydatic cysts.

Discussion:

Firstly, the patient underwent surgical treatment consisting of decortication and cystotomy of the lung cyst. Secondly, surgeons performed a closed total pericystectomy for the liver-attached hydatic cyst. In addition to that, Albendazole was administrated for three months after the intervention.

Ultrasound is the imaging modality of choice in the diagnosis of hydatid cysts. It is used to establish the diagnosis and to describe the location, number and stage of lesions. Both the WHO and Gharbi classifications are based on the ultrasound findings (1-2). The WHO classification divides cysts into active, transitional and inactive stages, which is relevant for treatment and follow up. Last, but not least, ultrasound helps to find complications such as pleural effusion or bile duct rupture. In these cases, treatment is essentially surgical with a controversial approach and a high risk of complications and recurrence (3).
