Aim of the study: Pulmonary cystic echinococcosis is a parasitic infection transmitted by dogs and occurring in livestock-raising areas. It is included among the neglected tropical diseases, according to the World Health Organization. Imaging plays a pivotal role in the diagnosis of this disease. While cross-sectional imaging modalities such as computed tomography and magnetic resonance imaging are preferred, lung ultrasound may be another feasible technique. Case description: We report a case of pulmonary cystic echinococcosis in a 26-year-old woman who was examined by contrast-enhanced ultrasound, which showed marked annular enhancement around the hydatid cyst, mimicking a superinfected cyst. Conclusions: Contrast-enhanced ultrasound examination in pulmonary cystic echinococcosis should be studied in a larger population to determine the value of additional contrast administration. In the present case report, no superinfected echinococcal cyst was seen despite marked annular contrast enhancement.
