Analysis of multislice spiral CT findings in the diagnosis of thoracic solitary fibrous tumor

Objective To explore thoracic solitary fibrous tumor(SFT) so as to improve the diagnosis of the disease. Methods CT images and clinical data of 31 cases of SFT proved surgically and pathologically were retrospectively studied. 4 cases of lung CT plain scan, 8 cases of lung CT one-time enhanced examination, 19 cases of lung CT scan and enhanced examination. Analysis of the location, shape, size, density, edge, enhancement characteristics of solitary fibrous tumor of the chest and the relationship with the surrounding tissue. Results 31 cases of solitary fibrous tumor of the chest 21 cases were female, 10 cases were male, 16 cases were in the right side, 13 cases were in the left side, 1 case in mediastinal, 1 case of pulmonary multiple.27 cases had clear boundary, with round or oval shape. 4 cases with irregular boundary, irregular shape and soft tissue density, and pleural effusion and adjacent rib destruction. 2 cases of arterial phase was not obviously enhanced and delay phase showed slight enhancement in enhanced scan, 11 cases of arterial were moderate inhomogeneous enhancement, 14 cases of arterial light moderate inhomogeneous enhancement, delayed enhancement was more obvious than in arterial phase. 27 of 31 cases were benign, 4 cases were malignant. Conclusions MSCT findings of thoracic solitary fibrous tumor has certain characteristics mostly showed clear boundary, abundant blood supply, a moderate inhomogeneous enhancement of soft tissue density nodules or masses.MSCT can clearly show the lesions characteristics, timely surgical resection was performed to improve the prognosis of patients.
