Axial T1-weighted image after contrast administration (A) and a FLAIR image (B) demonstrating a left parietal subcortical DVA with deep venous drainage (black arrow, A). Some faint enhancement is seen within the DVA drainage territory (arrowheads, A). Associated signal-intensity abnormality surrounds the DVA, extending into the white matter (white arrow, B).

Coronal T1-weighted image after contrast administration (A) and an axial FLAIR image (B) demonstrating a left frontal juxtacortical DVA (arrow, A) with marked associated signal-intensity abnormality (arrow, B). Some mild focal volume loss may also be present.

Axial T1-weighted image after contrast administration (A) and a FLAIR image (B) demonstrating a left frontal subcortical DVA (arrow, A), with moderate associated signal-intensity abnormality (arrow, B) extending to the ventricular margin. Mild associated ventricular enlargement is noted.
