[Intravascular large B-cell lymphoma with massive pulmonary lesions].
A 61-year-old man was admitted to our hospital with dyspnea on effort. Neither computed tomography scan nor chest X-ray film detected any specific findings that could explain hypoxemia. Since (67)Ga scintigraphy showed abnormal uptake in the bilateral lungs, transbronchial lung biopsy (TBLB) was performed. The TBLB specimen was diagnosed as intravascular large B-cell lymphoma (IVLBCL). There was no involvement of any other organ considered typical of IVLBCL. In cases showing clinical findings such as hypoxia despite mild pulmonary radiographic changes, a definitive diagnosis should be made using methods such as TBLB with consideration given to the possibility of IVLBCL.
