Question
A 4 months old boy presented with fever and cough for 7 days. His chest X-Ray had shown right upper and mid zone consolidation for which he had received ceftriaxone-sulbactum and amikacin for 7 days but there was no response. He underwent a HRCT chest that showed lobulated mass involving the entire mediastinum with extension to the chest wall on the right side and displacing the lungs suggestive of either a germ cell tumor or a thymoma. A CT guided biopsy was done that showed no identifiable tumor cells and only inflammatory pseudotumour. He was started on antituberculous therapy in view of persistent fever to which there was no response.
