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 MRI. Description: A 68-year-old woman presented with progressive complaints of dyspnea, cough, and limited weight loss. Postero-anterior and lateral radiographs (a, b) show a well-delineated mass (arrow) located posteriorly in the left lower lobe. Axial contrast-enhanced CT in the mediastinal window setting (c) shows a well-delineated homogeneous pleural-based mass. There is no invasion of the surrounding structures. On the axial T1-WI MR image (d), the lesion has a homogeneous isointense signal intensity to muscle. On the axial T2 blade FS MR image (e), the lesion has a low signal intensity with peripheral enhancement on the sagittal T2W FS MR image after i.v. contrast administration (f)
