Bilateral lung infiltration secondary to ruptured pulmonary hydatid cyst: a case report
Abstract
Background: Pulmonary hydatid cyst rupture is a rare but serious complication of Echinococcus granulosus infection, often presenting with acute respiratory distress and mimicking pneumonia or eosinophilic lung disease. Early diagnosis and appropriate management are essential to prevent complications.
Case presentation: A 44-year-old Persian woman presented with sudden-onset dyspnea, productive cough, and high-grade fever. Imaging revealed a multilayered cyst in the left lung with bilateral infiltrations. Serologic testing confirmed Echinococcus granulosus infection. The patient was treated with antibiotics and albendazole, followed by surgical cyst resection after 6 months. She remained asymptomatic 1 year postoperatively.
Conclusion: Ruptured pulmonary hydatid cysts can mimic severe lung infections. A combination of imaging, serology, and medical-surgical management ensures optimal outcomes, especially in endemic regions.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
