Accumulation of F-18 FDG in the infected pulmonary cyst in a patient with hydatid disease.

Echinococcosis is endemic in certain parts of the world, including Turkey. When the pulmonary cyst has characteristic features, it can be easily diagnosed, but when the appearance changes as a result of complications, the cyst may resemble a malignant lesion. We presented a complicated pulmonary hydatid disease patient who was referred to our department for PET-CT, after the detection of 2 lung lesions.
