Figures
- FIG 1.
Representative CM with an associated DVA. Axial SWI (A and C) and postgadolinium MPRAGE (B and D) of a CM in the left aspect of the pons (A and B). Magnified axial-section SWI just inferior to the CM shows the caput medusa of the DVA (C). Sagittal MIP of a postgadolinium MPRAGE shows the DVA abutting the CM (D).
- FIG 2.
Representative example of clustered CMs with an associated DVA. Axial SWI (A and C) and pre- and postgadolinium MPRAGE (B and D) of adjacent slices show a dominant left cerebral peduncle CM (A and B) and a DVA with additional small CMs (C and D).
- FIG 3.
Sample of a left frontal CM (A, SWI) with an associated DVA (B, postcontrast MPRAGE) that has both superficial (C) and deep (D) venous drainage.
