title: [Peripheral T-cell lymphoma unspecified with remarkably extensive airspace consolidations and ground-glass opacities of bilateral lung fields].
abstract: A 53-year-old man had presented to a nearby hospital with fever, dyspnea and multiple lymphadenopathy. Chest X-ray film and computed tomography had shown expanded airspace consolidations with air broncograms and surrounding ground-glass opacities in bilateral lung fields. Because his respiratory status had gradually worsened, he was transferred to our hospital and placed on the ventilator. Bronchoalveolar lavage were performed, showing abnormal lymphocytes which indicated infiltration of malignant lymphoma. Furthermore, a biopsy of the left inguinal lymph node revealed T-cell lymphoma. We finally diagnosed his pulmonary lesions as involvement of peripheral T-cell lymphoma unspecified in consideration of immunohistochemical estimation. Pulmonary involvement of malignant lymphoma is thought to be relatively uncommon. Therefore, this is considered an extremely rare case showing extensively spreading airspace consolidations and surrounding ground-glass opacities of bilateral lung fields caused by the infiltration of malignant cells along with lymphoid tissues. Because these radiological findings may indicate a severe status of lymphoma, it is necessary to diagnose and treat them immediately. From this point of view, we report this case with useful information concerning differential radiological diagnosis.
