Ruptured Hydatid Cyst with an Unusual Presentation

الملخص EN

Ruptured pulmonary hydatid cyst may sometimes cause complications like empyema, bronchopleural fistula, and collapsed lung.

These complications may mislead the diagnosis and treatment if prior evidence of cyst has not been documented before rupture.

We present a case of a young male who presented with complete collapse of left lung with pyopneumothorax and bronchopleural fistula which was misdiagnosed as pulmonary tuberculosis.

He was referred to us from peripheral hospital for pneumonectomy when his condition did not improve after six months of antitubercular chemotherapy and intercostals drainage.

On investigation, CT scan revealed significant pleural thickening and massive pneumothorax restricting lung expansion.

Decortication of thickened parietal and visceral pleura revealed a ruptured hydatid endocyst, and repair of leaking bronchial openings in floor of probable site of rupture in left upper lobe helped in the complete expansion of the collapsed lung followed by uneventful recovery.
