Excerpt
Cerebral ‘venous malformation’ or ‘developmental venous anomaly’ is a relatively common vascular malformation found incidentally on magnetic resonance (MR) imaging, may be associated with other vascular malformations—most frequently, cavernous malformation (13–40 %) [
1,
2], and occurs rarely with varices [
3‐
8]. We present a case of venous malformation with associated varix and hyperintensity of surrounding brain parenchyma that was identified on fluid-attenuated inversion recovery (FLAIR) image. We believe that increased blood pressure in the draining vein may have caused the varix and increased signal intensity. Though abnormality of signal intensity on T
2-weighted or FLAIR images in the drainage territory of venous malformations is reported, we believe ours is the first case of venous malformation with associated varix and hyperintense surrounding brain parenchyma diagnosed by MR imaging. …
