  		FIG 1. Infraconal spinal cord AVM (case 1).

A, DSA of a selective catheterization of the left intercostal artery at the T11 level shows an enlarged artery of Adamkiewicz (arrows).

B, Corresponding anteroposterior MIP projection of the MR angiogram shows similarity in the shape of the anterior midline vessel with that depicted in the arterial phase of the DSA (arrows).

C, Sagittal view shows the artery of Adamkiewicz on the anterior surface of the cord (arrows) and, dorsally, the enlarged draining posterior median vein (arrowheads).

  		FIG 2. Cervical spinal cord AVM (case 3).

A and B, DSA with simultaneous contrast injection in both subclavian arteries (A) and targeted anteroposterior MIP projection of the MR angiogram (B) show the main arterial feeder, which originates from the left costocervical trunk (arrow). The multicompartmental spinal cord AVM drains mainly into an enlarged posterior median vein (arrowhead).

  		FIG 3. Fistulous spinal cord AVM with a varicose venous drainage (case 5).

A and B, Both the late phase of selective DSA (A) and the MIP projection of the MR angiogram (B) show a tortuous, markedly enlarged draining vein (arrowheads). The arterial supply from the right 12th intercostal artery can be seen on MR angiogram in its proximal segment and at its sharp bend (arrows).

  		FIG 4. Spinal dural AVF at the left T11–T12 neural foramen (case 8).

A and B, Selective DSA (A) and anteroposterior MIP projection of MR angiogram (B) depict the fistula (long arrow) located at the T11–T12 neural foramen. An enlarged medullary vein (short arrow) draining the fistula to the tortuous, dilated posterior median vein (arrowheads) is clearly seen.

C, An axial targeted view from the MR angiographic data shows the location of the fistula (arrow) at the left T11–T12 neural foramen.

  		FIG 5. Bilobular hemangioblastoma in a patient with von Hippel-Lindau disease (case 10).

A and B, DSA with selective contrast administration into the left intercostal artery at T11 level (A) and the anteroposterior MIP projection (B) correspondingly show the two solid masses (arrowheads) fed by the enlarged artery of Adamkiewicz (arrows), which is partially obscured in the intradural course by enlarged draining perimedullary veins.

C, MIP axial targeted projection shows the arterial supply from the left T11 level (arrow).
