Abbreviations
- Brain capillary telangiectasia (BCT)
Synonyms
- Capillary malformation
- Not capillary "hemangioma"
- Hemangiomas are true benign vasoformative neoplasms
- Usually in face, scalp, back, chest, orbit
- Less common: Dura, venous sinuses
- Exceptionally rare in brain parenchyma
Definitions
- Cluster of enlarged, thin-walled capillaries surrounded and separated by normal brain [usually white matter (WM)]
