A 14-year-old boy presented to us in July 2009 with low-grade, evening rise fever since March 2008. He also complained of reduction in appetite and weight loss of 8 kg during this period. He had a mild dry cough. However, there was no history of shortness of breath, chest pain, hemoptysis, hoarseness of voice, or dysphagia. There was no other significant history to localize the cause of fever. He received antituberculosis therapy (ATT) for these symptoms and abnormal chest radiograph. He was treated for the first time for 4 months from March to June 2008 and then for 6 months in a private hospital without any relief in his symptoms.
