Calcifying fibrous tumors (CFTs) are rare benign mesenchymal tumors consisting of hyalinized collagenous fibrotic tissue with a lymphoplasmacytic infiltrate and dystrophic calcifications. Radiographic features have seldom been described, and there are no reports describing magnetic resonance imaging (MRI) findings. Here, we report a pleural CFT in a 47-year-old woman. The tumor mimicked an intrapulmonary lesion on initial computed tomography scans but migrated inferiorly and presented as an extra-pulmonary lesion on MRI. The tumor showed iso-signal intensity on T1-weighted images (WIs), low signal intensity on T2WIs, and slight rim enhancement on enhanced T1WIs.
