Bottom Line: A 67-year-old man recovered after antibiotic treatment for community-acquired pneumonia.Follow-up chest computed tomography (CT) revealed an increase in the extent of the right posterior mediastinal mass that we had considered to be pneumonic consolidations on previous CT scans.Through percutaneous needle biopsy, we diagnosed IgG kappa type extramedullary plasmacytoma of the posterior mediastinum.

ABSTRACT
Plasmacytomas are extramedullary accumulations of plasma cells originating from soft tissue. Mediastinal plasmacytoma is a rare presentation. A 67-year-old man recovered after antibiotic treatment for community-acquired pneumonia. However, on convalescent chest radiography after 3 months, mass like lesion at the right lower lung field was newly detected. Follow-up chest computed tomography (CT) revealed an increase in the extent of the right posterior mediastinal mass that we had considered to be pneumonic consolidations on previous CT scans. Through percutaneous needle biopsy, we diagnosed IgG kappa type extramedullary plasmacytoma of the posterior mediastinum.

(C, D) Follow-up chest CT scan revealing an increased mass in the right posterior mediastinum with improvements in other pneumonic consolidations at other lung fields.

Mentions: A computed tomography (CT) scan of the chest was performed, and revealed multiple pulmonary consolidations, ground-glass opacities, and interstitial septal thickenings in both lower lung fields (Figure 2A, B). Based on these observations, we made a diagnosis of CAP and initiated antimicrobial therapy of intravenous ceftriaxone 2 g plus azithromycin 500 mg. After treatment of CAP, the clinical findings of the patient stabilized, and the patient was discharged on hospital day 4.
