22-year-old woman with developmental venous anomaly. Axial contrast-enhanced CT reveals an area of decreased attenuation within the genu and posterior limb of the right internal capsule, with a prominent enhancing vessel within the central portion of the lesion, consistent with a nonhemorrhagic infarction from a developmental venous anomaly.

These findings represent a DVA with venous thrombosis and infarction (Fig. 1A). A subsequent brain MRI showed an acute infarction with abnormal signal on the T2 (Fig. 1B), FLAIR, diffusion (Fig. 1C), and gadolinium enhanced T1 sequences within this same area. A curvilinear, prominent vessel coursed through the infarction, representing the thrombosed DVA (Fig. 1D).
