(a) Oblique right subcostal scan. A voluminous inhomogeneous formation with an evident wall (arrows) occupies segment 2–3–4–8 and is in contact with the diaphragm. (b) The right coronal scan reveals an inhomogeneous subcutaneous collection (s) of liquid communicating with a similar collection in the right pleura (p), which in turn communicates with the hepatic lesion (h). (c) Intercostal percutaneous echoguided drainage allowed diagnosis of communicating hepatic, pleural and subcutaneous hydatid cysts infected with Pseudomonas aeruginosa.
