General Findings
- Average size is 1 cm or less in diameter.
- Fresh hemorrhage may be present.
- Venous angioma may be present.
T1-Weighted Sequence
- Hyperintense centrally with varying levels of intensity reflecting past hemorrhages of varying duration.
- Hypointense halo surrounds the hyperintense core. This is due to hemosiderin (21).

T2-Weighted Sequence
- Hypointense central core with scattered small areas of hyperintensity.
- Hyperintense halo due to hemosiderin is larger that halo seen on T1-weighted sequneces.
