Diagnosis With Brief Discussion
- Diagnosis
- Solitary fibrous tumor of pleura
- Radiologic Findings
- Fig. 1,2
CT scans demonstrate a large heterogeneously enhancing soft 뻯issue mass in the left hemithorax with internal linear and geographic areas of low attenuation and calcification. Enhancing portions of the lesion have a nodular pattern of attenuation

- Brief Review
- Solitary fibrous tumors are rare primary pleural neoplasms that may grow to large sizes and typically affect symptomatic men and women over the age of 40 years.
Small solitary fibrous tumor of pleura without gross necrosis, hemorrhage, or cystic change may exhibit homogeneous attenuation on unenhanced and less frequently on contrast-enhanced chest CT scans. However, the majority of solitary fibrous tumor of pleura exhibit heterogeneous attenuation on CT scans, characterized as intralesional geographic, focal or linear areas of low attenuation that often correlate with hemorrhage, necrosis, or cystic changes. Calcification may occur in one-fourth of cases. Atelectasis of the adjacent lung and mass effect on the mediastinum are common associated findings.
