From: Solitary fibrous tumor of the lung: diagnostic challenges and surgical management

Table 2. Diagnostic tests and findings in the present case.

Diagnostic test	Findings	Interpretation
Chest CT	Large hypervascular mass in the left lower lobe (15 × 14.5 × 12.5 cm)	Suspicious of SFT
CT-guided biopsy	Spindle-cell neoplasm	Suggestive of SFT
Bronchoscopy	No endobronchial involvement	Non-diagnostic
Pulmonary function test	FEV₁ 1.17 L (46% predicted)	Reduced pulmonary reserve
Echocardiography	Preserved biventricular function	Suitable for surgery
Histopathology	Spindle-cell tumor with increased mitotic activity and necrosis	Consistent with SFT
Immunohistochemistry	Nuclear STAT6 positivity	Diagnostic confirmation of SFT

CT: computed tomography; SFT: solitary fibrous tumor; FEV₁: forced expiratory volume in one second; STAT6: signal transducer and activator of transcription 6.
