Developmental venous anomalies and cerebral cavernous malformations: Partners in crime

Figure 3 Developmental venous anomaly image. A and B: T1-weighted axial (A) and coronal (B) images following intravenous gadolinium administration demonstrate a developmental venous anomaly in the left temporal lobe, evident by the characteristic “caput medusae” appearance and the draining vein (dashed circle); C and D: When compared to the contralateral side, dynamic susceptibility contrast magnetic resonance perfusion demonstrates increased relative cerebral blood volume (C), and arterial spin-labeling perfusion displays increased relative cerebral blood flow (D) (dashed oval) in the corresponding territory of the developmental venous anomaly.
