Lung intravascular large B-cell lymphoma with ground glass opacities on chest computed tomography: a case report

Intravascular large B-cell lymphoma (IVLBCL) is a rare type of extranodal large B-cell lymphoma characterized by the selective growth of lymphoma cells within the lumina of vessels, particularly within capillaries, with exception of larger arteries and veins. The authors reported a case of a 45-year-old woman who was admitted in hospital with refractory fever, cough and progressive dyspnea despite of receiving broad-spectrum antibiotics. Computed tomography (CT) of the lung showed bilateral patchy ground-glass opacities with some pleural effusion in the left lung. A CT-guided percutaneous lung biopsy was performed and primary pulmonary intravascular large B-cell lymphoma was diagnosed by histopathology, immunophenotype and fluorescence in situ hybridization. The patient's general status was improved after chemotherapy with R-CHOP. CT-guided percutaneous biopsy of lung is a safe and accurate diagnostic procedure in IVLBCL.
