Imaging description Pleural lipomas are benign, rare, and asymptomatic tumors . The pleural location and fat content of a pleural lipoma is not always identifiable on chest radiographs . CT will show a well-defined, homogeneous, fat attenuation mass (HU less than –50) with obtuse margins along the pleura, which displaces adjacent pulmonary parenchyma [1, 2] [Figures 66.1–66.4]. Pleural lipomas are hyperintense on T1-weighted images and moderately intense on T2-weighted images on MRI . Importance A pleural lipoma is usually inconsequential but may present a diagnostic dilemma on radiographs and, rarely, CT as they must be distinguished from other causes of a nodule or mass.
