Background: Multiple myeloma is a common disease, accounting for about 10% of hematologic malignancies in the United States. For eligible patients, the treatment of choice includes induction therapy (usually involving newer biologic agents) followed by autologous stem cell transplant; however, this treatment is generally not considered curative, and relapses usually occur. However, extramedullary relapse is an uncommon presentation, and relapses that involve the lungs have only rarely been described.; Case Report: We report the case of a patient who underwent an autologous stem cell transplant for multiple myeloma and subsequently relapsed with diffuse pulmonary nodules. She then had a rapid clinical and serologic response following initiation of salvage therapy.; Conclusion: This case is remarkable for both the radiographic appearance of the pulmonary involvement, as well as the rapid resolution of these findings after 2 cycles of treatment with bortezomib, dexamethasone, and lenalidomide.
