Aims and objectives

Solitary fibrous tumour of the pleura (SFTP) is a mesenchymal tumour that tends to involve the pleura, although it has also been described in other thoracic areas and in extrathoracic sites. It is usually a benign tumour, although a small percentage of patients may develop locoregional recurrence. The aim of the study was to analyze computed tomography (CT) findings of SFTP.

Methods and materials

A retrospective analysis of CT features was conducted for 10 patients with diagnosis of SFTP with CT from January 2005 to July 2014. 6 patients had pathologically confirmed SFTP(3 of them benign SFTP), 2 patients had nondiagnostic or absent pathologic specimens, one had diagnosed of SFTPby fine needle- aspiration but of ganglioneurofibroma after biopsy, and one had pathological diagnosis of scwannoma.

Results

There were 6 males and 4 females, with a median age of 63.2 years, and 8 patients (80%)were more than 60 years old.Chest X-ray was used to examine 4 cases. In 3 cases, clearpleural space-occupying signs or masses(75% positive rate) were found in the posteroanterior chest film Fig. 1 Fig. 2 , whereas the other case was not available in the database. A chest CT diagnosis was conducted for 60 % of the patients. 66.6 % of SFTPwere located in the right hemithorax. The average...

Conclusion

We found that most of SFTPhad CECT values higher than 50 UH and clear boundaries. In addition, the largest tumors can have calcifications, cause mediastinal displacement or associate pleural effusion. The diagnostic accuracy rate of CT imaging reached 60%.
