INTRACEREBRAL HEMORRHAGE / VASCULAR MALFORMATIONS
Capillary telangiectasia
Created 24/02/2022, last revision 22/01/2023
- the second most common vascular malformation (16-20% of all malformations) after venous angioma (DVA)
- the lesion is composed of vessels that resemble dilated capillaries (lumen 20-500μm) and are separated with normal brain tissue (unlike cavernous malformations)
- about 2/3 of the lesions have a visible small draining vein
- typical localizations: pons, cerebellum, and spinal cord
- the vast majority of telangiectasias are asymptomatic (incidental finding on MRI)

Differential diagnosis
- tumor or metastasis
- subacute ischemia with a hemorrhagic component
- cerebritis
- vascular malformation
Management
- most commonly conservative approach
- the lesion is difficult to access
- almost always asymptomatic
- MRI follow-up is not required if the imaging appearance is typical
