Pulmonary hydatic disease presenting as solid mass with haemoptysis in a child.

A middle childhood HIV-negative female patient presented with three episodes of haemoptysis. The chest X-ray demonstrated an oval-shaped, well-circumscribed left upper lobe homogenous opacification. She did not respond to tuberculosis treatment. A left upper lobectomy was performed for a solid mass in the lung, and hydatic disease was histologically confirmed. Calcification was found in the pulmonary lesion. Pulmonary hydatic cyst rarely presents as a solid lesion with calcifications and haemoptysis.
