(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.

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.
(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.

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.
