Capillary telangiectasia is a vascular abnormality primarily of the brainst em. The clinical relevance is unclear as is the association with clearly pa thologic findings such as cavernous haemangioma. We report on four cases wi th capillary telangiectasia proven by follow-up und describe the imaging ch aracteristics. T2 abnormality was only observed in half of the patients as was the presence of a discernable collecting vein. Whereas two cases were i ncidental findings in neurologically normal persons and one had symptoms cl early attributable to lacunar stroke, one patient may have had symptoms due to the vascular abnormality in the pens.
