Diagnosis With Brief Discussion

Diagnosis
Benign Localized Fibrous Tumor of the Pleura
Radiologic Findings
Chest radiographs obtained 3 years ago show a well-defined opacity in the right lower lung zone along the major fissure. The lesion increased in size 3 years later. Chest CT scans obtained a week ago show a well-defined mass in the lower portion of the right oblique fissure, which is partly well-enhanced following intravenous administration of contrast media. Surgery confirmed the intrafissural location of the mass and no pulmonary invasion.
Brief Review
Differential diagnosis may include localized empyema within the major fissure, lung cancer invading the fissure, or localized fibrous tumor. However, features of slow growth, mostly intrafissural location, and well-enhancement favor the diagnosis of localized fibrous tumor of the pleura.
