Ruptured pulmonary hydatid disease mimicking a lung mass: diagnosed by flexible video bronchoscopy

Echinococcosis is frequently seen in an endemic country like India. The vast majority of infestations in humans are caused by Echinococcosis granulosus. The cyst is most commonly seen in the liver in about 74% of the cases, followed by pulmonary involvement in about 24% of cases. In our case report, a 25-year-old man presented with a mass-like lesion in the upper and middle lobe of the right lung. The patient had deteriorated clinically as the mass like opacity grew in size. Here, we have highlighted an uncommon presentation of hydatid disease of the lung diagnosed by video bronchoscopy and bronchoalveolar lavage (BAL) as clinico-radiological examination along with FNAC (fine-needle aspiration cytology) of the lesion proved insufficient tools to make a diagnosis.
