[Echinococcosis Detected by a Solitary Shadow in the Lung]

Here we report a rare case of pulmonary coin lesion due to echinococcosis. An woman in her 60s who has no symptom was found a nodular shadow of the left lung incidentally. Since the nodule was enlarging, surgical treatment was done. Pathologically, it was diagnosed as an echinococcosis of the lung. It was pulmonary solitary echinococcosis without any lesion in other organs.
