Inadvertent rupture of an echinococcal cyst: case report and review of literature.

Echinococcal disease is infrequently seen in developed countries. In the United States, most cases are imported from endemic areas. Although frequently asymptomatic, enlarging cysts can cause local symptoms. Cysts can rupture spontaneously or as a result of trauma. Optimal management of accidental rupture of echinococcal cysts with little or no symptoms is not well known. The authors describe a case of inadvertent rupture of an echinococcal cyst and review the English literature to determine an acceptable management strategy.
