Discussion of Capillary telangiectasia
- Capillary telangiectasias are cerebral vascular malformations that consists of small areas of abnormally dilated capillaries within otherwise normal brain tissue.
- The presence of normal brain tissue between the capillaries is a pathologic characteristic that distinguishes capillary telangiectasias from cavernous malformations, although they may resemble each other on imaging studies.
- Most commonly occur in the pons.
- Capillary telangiectasias are usually solitary, but they may also be found in association with other brain vascular malformations such as cavernous malformations and developmental venous anomalies.
- Although almost all patients with capillary telangiectasias are asymptomatic, capillary telangiectasias have been associated with minor symptoms such as vertigo, headache, and dizziness, as well as weakness and seizures.
 Imaging Findings for Capillary telangiectasia
- CT does not usually detect
- MRI findings in capillary telangiectasias are variable, but contrast enhancement is required for diagnosis or even detection in almost all cases.
- The enhancement pattern is described as lacelike and is usually subtle.
- Increased signal intensity may be seen occasionally T2-weighted images.
- Susceptibility dephasing is seen on GRE sequences.
