Cavernomas capillary telangiectasia

The diameter of the blood vessels lies within the range 30-50 pm. No brain tissue is present between the blood cavities, which are embedded into connective tissue. This is from a histopathological point of view the major difference between cavernomas and capillary telangiectasias. In the latter, there is intervening brain parenchyma between the vascular channels. However, since Rigamonti et al. (1987, 1988) found more than 30% incidence of intervening brain parenchyma in more or less typical caverno-... 

Several authors found an association of capillary telangiectasias with cavernomas in their patients (Kuker et al. 2000), or suggested that both vascular ahnormalities have a common origin (Rigamonti et al. 1991). However, in contrast to cavernomas, the occurrence of capillary telangiectasias seems to be... 

Hereditary hemorrhagic telangiectasia (Rendu-Osler disease) is not associated with cerebral capillary telangiectasia, but with other forms of cerebral vascular malformations (Maher et al. 2001), mainly true pial arteriovenous malformations, dural arteriovenous malformations, and, rarely, cavernomas.
