Figure 1
Plain CT and contrast-enhanced CT (CECT) show a lobulated, heterogeneously enhancing mass with several non-enhancing areas.
Figure 2
T2FLAIR and DWI show a midline shift but no diffusion restriction.
Figure 3A and B
Coronal and sagittal T1-weighted images after intravenous administration of gadolinium contrast clearly demonstrate the dural tail sign.
Figure 4
T1-weighted images before and after intravenous administration of gadolinium contrast show heterogeneous contrast enhancement with less enhancement of the central areas.
Figure 5
Hematoxylin-eosin stain with ×200 magnification (A) shows a high concentration of cells. CD 34 stain with ×200 magnification is positive (B). CD 99 stain (×200) (C), and STAT-6 stain (×200) (D) confirm the positive result.
