Air Bronchogram Sign in Primary Pulmonary T-Cell Lymphoma with Multiple Nodules

A 33-year-old man was admitted with fever, chest pain and multiple nodules. infection was the first diagnosis and antibiotic therapy was considered for the patient. after two weeks of no improvement, infection was ruled out and based on the ct findings, metastatic tumor of the lung was strongly considered. the ct imaging of the patient also demonstrated air bronchogram in a mass-like lesion and one nodular lesion. eventually, the patient underwent ct-guided transthoracic needle biopsy of the mass-like lesion in the right upper lung. the sample confirmed a primary pulmonary t-cell lymphoma. the patient entered complete remission after one course of chop (cyclophosphamide, adriamycin, vincristine and prednisone) combination chemotherapy. during the second course of combination chemotherapy, the patient died of an uncontrollable secondary pulmonary infection.
