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.

Figure 1: Chest radiography images of the patient. (A) Initial chest radiography showing multiple pulmonary consolidations. (B) A mass-like lesion without the loss of right cardiac borders on a routine follow-up chest radiography after 3 months.

Mentions: Chest radiography showed multiple pulmonary infiltrations in the right lung fields (Figure 1A). White blood cell count was 8,000/mm3 with 76.0% segmented neutrophils, 13.7% lymphocytes, and 1% eosinophils. C-reactive protein and procalcitonin were 23.34 mg/dL and 0.579 mg/dL, respectively. Other routine blood chemistry tests were all normal. Arterial blood gas analysis revealed pH 7.439, PCO2 36.3 mm Hg, PO2 52.4 mm Hg, and HCO3- 24.9 mmol/L.
