Double cerebral venous angiomas: MRI.
Using a 1.5 Tesla MR imager, we examined 58 patients with venous angiomas (VA); images were also obtained following contrast medium in 33. Of the 58 patients 29 underwent selective cerebral angiography. We found in all 63 VA, including two with arterial components; 5 of the 58 patients thus each had two VA. The VA were supratentorial and bilateral in 4 cases; the remaining patient had supra- and infratentorial VA. Of these 5 patients, 4 received intravenous contrast medium and in 2 of them, the second VA was so small that it was detectable only on the contrast-enhanced images. The incidence of double VA in patients receiving contrast medium was 12% (4/33).
