case_images: (A) T1-weighted magnetic resonance imaging showing an isointense mass. (B) T2-weighted imaging showing a hyperintense mass with associated spinal cord edema in the rostral region of the lesion. (C) Homogeneous enhancement after gadolinium administration. (D) Three-dimensional computed tomographic angiography reconstruction showing a high-flow hypervascular lesion.

case_images: The lesion was isointense on T1-weighted imaging (Figure 1A) and hyperintense on T2-weighted imaging (Figure 1B). Homogeneous and bright contrast enhancement was noted after intravenous injection of gadolinium-diethylenetriaminepenta-acetate (Gd-DTPA) (Figure 1C). A further three-dimensional computed tomographic angiography (CTA) reconstruction was requested, which demonstrated the mass was remarkably enhanced (Figure 1D), suggesting its rich vascularization; nevertheless, identifying its definite feeding artery is quite challenging.
case_images: (A) Haematoxylin and eosin staining (original magnification x200) showing uniform spindle cells arranged in interlacing fascicles. (B) Sagittal, (C) coronal, and (D) axial contrasted T1-weighted imaging confirming a complete resection of the tumor.

case_images: Based on the immunohistochemical profiles and the histopathological fascicular spindle cell morphology, the lesion was diagnosed as SFT (Figure 2A). The postoperative MRI confirmed a complete resection (Figure 2B-D), and the postoperative course was uneventful.
