Disseminated hydatid disease involving orbit, spleen, lung and liver.

Orbital hydatid disease is rare, even in endemic areas. We present a case of disseminated hydatid disease involving the orbit, spleen, lung and liver in a lady aged 35 years. Based on a typical clinical presentation, presence of eosinophilia, a positive indirect haemagglutination test for hydatid disease and presence of similar disseminated, anechoic cystic masses in the liver, lung, spleen and orbit on imaging studies, the diagnosis of hydatid cyst was seriously considered before surgery. Aspiration of the cyst, followed by cryo-extraction of the cyst wall through transconjunctival route was safely performed. Histopathological examination confirmed the diagnosis. In conclusion, multisystemic involvement of liver, lung and spleen in a case of orbital hydatid cyst has never been reported before. The surgical technique adopted in this case is safe and effective.
