Appearance of venous malformations on magnetic resonance imaging.
The magnetic resonance (MR) imaging appearance of venous malformations, all angiographically verified, was evaluated in 11 patients. A venous malformation is characteristically depicted as a tubular area of decreased signal intensity in the white matter of the brain. In one patient, a histologically verified cavernous malformation was also present with a characteristic mixed signal-intensity core on the T2-weighted MR images. Care should be used when evaluating venous angiomas to exclude the presence of a lesion with associated prominent venous drainage, such as a glioma.
