A 25-year-old male from Guntur District of Andhra Pradesh presented to the Tuberculosis and Chest department of NRI General Hospital, Chinakakani with complaints of productive cough, chest pain, hemoptysis, and dyspnoea for the last four months. There was history of occasional fever but no weight loss. Physical examination revealed bilateral rhonchi on auscultation.
Blood picture showed leucocytosis with eosinophilic preponderance. Routine examination of blood and urine disclosed normal findings and the sputum was repeatedly negative for acid-fast bacilli. Computed tomography (CT) scan impression was a 6x6.9x5.9 cm hypodense lesion in the posterior segment of the lower lobe of the right lung with minimal adjacent loculated effusion-probably lung abscess [Figure 1]. Ultrasound guided aspiration was done and fluid analysis revealed viable scoleces [Figure 2].
A large unilocular hydatid cyst was removed from the right lung through a right thoracotomy. Oral albendazole 400 mg b.i.d. was given for 5 days preoperatively and 4 weeks post operatively.
