A 63-year-old man underwent splenectomy, partial wedge resection of the stomach, distal pancreatectomy, and repair of a small diaphragmatic laceration for non-Hodgkin B-cell lymphoma of the spleen. Pathological analysis revealed negative resection margins. The patient received no postoperative chemotherapy or radiation.

Twelve months following surgery, the patient began to have fatigue, weight loss, recurrent sepsis, chronic pulmonary infections, and intermittent foul-smelling sputum. Chest radiography and computed tomography repeatedly revealed left lower lobe infiltrate (Figure 1). Alveolar lavage documented an Escherichia coli pneumonia that failed to improve following multiple courses of antibiotics. Findings on positron emission tomography were normal other than increased uptake in the left lower lobe. Colonoscopy results were unremarkable. Subsequently, a barium enema was completed (Figure 2).
