2. Figure
A, Thoracic MRI without and with intravenous contrast demonstrated 19.0 × 13.8 × 19.3 cm heterogeneously enhancing mass with slightly lobulated margins that occupies nearly the entire right hemithorax sparing the right upper lung. B, F18-FDG PET scan demonstrated heterogeneously moderate FDG uptake mass in the lower one half of the right thoracic cavity. C, Gross inspection revealed a 3530-g tan-yellow, focally necrotic mass that extends to involve the pleura and lung tissues. D, Microscopic findings showed a patternless architecture of alternating hypocellular and hypercellular areas of spindle-shaped cells consistent with a solitary fibrous tumor. FDG = fluorodeoxyglucose; MRI = magnetic resonance imaging; PET = positron emission tomography.
