Laparoscopic treatment of a large simple hepatic cyst misinterpreted as hydatid.

In addition to becoming the gold standard for surgical treatment of a number of diseases, laparoscopy is sometimes needed as a diagnostic method to differentiate one disease from another. We present a case of a 75-year-old man with an incidentally found liver cyst, which was suspected to be hydatid. We performed a laparoscopic deroofing and a simple cyst was found, which diagnosis was confirmed the final pathological analysis of the cyst wall.
