From: Tumor and tumorlike conditions of the pleura and juxtapleural region: review of imaging findings
Diagnosis: solitary fibrous tumor. Technique: standard chest radiography, contrast-enhanced chest CT and 18FDG-PET CT. Description: An 84-year-old man presented to the emergency department with clinical symptoms of weight loss, altered behavior, and fever. His bloodwork showed signs of hypoglycemia. Standard antero-posterior chest radiograph (a) shows a large area of consolidation in the left hemithorax, with a silhouette sign on the left heart border and left diaphragm. Coronal reformatted contrast-enhanced CT-image (b) shows a well-defined mass in the left hemithorax. The mass has a heterogeneous aspect with intralesional hypodense areas due to necrosis, cystic degeneration or myxoid component. The mass does not show an aggressive growth pattern: there are no imaging signs that suggest invasion in the adjacent thoracic aorta. There is no increased 18F-FDG uptake in the tumoral mass on the 18-F-FDG PET study (c). The combination of imaging findings and clinical findings was suggestive of Doege–Potter syndrome, which was confirmed after histopathologic examination of the large resected pleural mass
