Giant symptomatic capillary telangiectasia of the brain Telangiectasia capilar cerebral gigante sintomática

A 30-year-old female reported sporadic paresthesia and tremors in the left hand, hemiface, and hemibody. MRI showed a lesion in the left pontomesencephalic junction (Figure 1), with brushlike enhancement after gadolinium administration, well depicted with maximum intensity projection (MIP) technique (Figure 2). Despite its unusually large dimensions, the lesion was diagnosed as a capillary telangiectasia based on its characteristic imaging findings. The clinical picture was attributable to the lesion, and biopsy was not pursued. It is important to bear in mind that larger lesions may also occur, and the occurrence of symptoms may be related to the affected sites.
