fig 2. — Case 3: 24-year-old woman with VHLD.

A, Sagittal T1-weighted FSE image (700/10/6) shows a large, round, hypointense tumor in the left vertebral foramen between S1 and S2. Note vascular flow voids within the tumor.

B, Sagittal T2-weighted FSE image (4100/121/5) shows mixed iso- and hyperintense tumor.

C, Sagittal T2-weighted FSE image (4100/121/5), medial to slice in B, shows serpentine vascular flow voids (arrows).

D, Contrast-enhanced axial T1-weighted FSE image (740/8.6/4) shows intensely but heterogeneously enhancing tumor that was confirmed to arise from left S1 nerve root at surgery.

E and F, Arterial (E) and venous (F) phases of digital subtraction angiograms, right anterior oblique 30° view, with left internal iliac artery catheterized, show intense tumor stain, dilated lateral sacral arteries that supply the tumor (curved arrows, E), and early venous filling (straight arrows, F), indicating the arteriovenous shunt in the tumor. This vein corresponds with the flow voids seen in C.
