Abstract

A 30-year-old woman presenting with hemoptysis followed by acute respiratory distress developed a diagnostic pulmonary radiographic finding, called the sign of the camalote, indicative of ruptured hydatid cyst. Her computed tomography scan demonstrated the characteristic detached parasitic membrane floating on cystic fluid, reminiscent of Amazonian camalote leaves. She was managed successfully surgically. Ruptured hydatid cysts may present as a diagnostic challenge, in which the sign of the camalote may provide an important clue for this serious complication.

Keywords: echinococcus; hydatid cyst; sign of the camalote; water lily sign.
