Case 29-2007

A 51-year-old man was admitted to this hospital because of a pulmonary nodule. Helicobacter pylori infection had been diagnosed 5 years earlier, and a subtotal gastrectomy had been performed for adenocarcinoma of the gastric antrum and pylorus 2 years earlier. In the year before admission, pleuritic chest pain developed, and multiple pulmonary nodules and cysts were seen on computed tomography (CT). Two weeks before admission, a new pulmonary nodule was seen on follow-up CT. A diagnostic procedure was performed.
