Imaging findings

An incidental, well-circumscribed mass was noted on chest X-ray in the right middle lobe. CT showed the mass to be intrapulmonary, barely touching the pleura, and centered in the right middle lobe. A PET scan showed no uptake. The mass had grown between exams from 2013 to 2014. Trace pleural thickening was noted but not a significant effusion.

Key takeaways

This case, though intrapulmonary (not typically plural), was biopsy-proven to be a fibrous tumor of the pleura. It demonstrated growth over time and was PET-negative. The presence of pleural effusion, which suggests malignancy for pleural tumors, was not a prominent feature here.
