Abstract

To describe presenting features of pulmonary infarction that may simulate those of lung cancer. We reviewed the medical records of 43 patients with pulmonary infarction diagnosed by surgical lung biopsy at the Mayo Clinic in Rochester, Minn, from January 1, 1996, to December 31, 2002. Of 16 patients presenting with an undiagnosed solitary pulmonary nodule or mass, 6 had features suggestive of lung cancer on additional imaging, including abnormalities on contrast-enhancement computed tomography (CT), positron emission tomography (PET), or nonsurgical lung biopsy before surgical resection. We examined the presenting symptoms, epidemiological, clinical, and radiological features, and clinical course of these 6 patients. All 6 patients, ranging in age from 41 to 85 years, had a history of smoking and underlying cardiopulmonary disease. In 5 of the 6 patients, CT showed a nodule in the subpleural region of the lung. Three patients had abnormalities on contrast-enhancement CT, 2 had abnormalities on PET, and 1 had abnormal cytologic findings on a transthoracic needle biopsy of the lung; all these studies showed abnormalities suggestive of lung cancer. Surgical resection of the nodule or mass revealed pulmonary infarction associated w...Continue Reading
