A 22 year old women presented with complaints of vague pain in the chest for three months and cough with expectoration for six days before admission. On examination, she was afebrile and non-dyspnoeic. Her pulse rate, respiration rate, and blood pressure were within normal limits. Her white cell count was only mildly raised. She had a normal haemoglobin concentration and erythrocyte sedimentation rate. Mantoux test was negative.

Chest radiography (fig 1) and computed tomography (fig 2) showed bilateral, multiple, well defined lung parenchymal nodules, randomly distributed throughout both lung fields. An air crescent was also seen in one of the nodules in the right lower lobe (fig 2B). Casoni’s test was done later, which was positive. No mediastinal or hilar lymphadenopathy and no pleural or pericardial effusion was seen.
