Capillary telangiectasia of the brain stem diagnosed by susceptibility-weighted imaging

J Comput Assist Tomogr. Nov-Dec 2006;30(6):980-2. doi: 10.1097/01.rct.0000220810.81221.27.


A case of brain stem capillary telangiectasia diagnosed by susceptibility-weighted imaging is reported. A small enhancing pontine lesion was found on postcontrast T1-weighted MR images in a 56-year-old woman with human T-cell leukemia virus type 1 infection. Imaging diagnosis was difficult with conventional MR imaging because the lesion did not show characteristic signal loss on conventional gradient-echo images. SWI was useful for imaging diagnosis as it demonstrated marked signal loss of the lesion.
