Findings:
A well-defined rounded intra-axial lesion measuring 10 x 10 mm seen in the right temporal operculum. It displays a mixed-signal intensity centrally on both T1 and T2 with peripheral T2 hypointense hemosiderin staining and prominent blooming on gradient echo sequence. There is no surrounding edema to suggest recent hemorrhage.
On the SWI sequence a prominent vascular structure is seen in association with the lesion.
A few non-specific T2/FLAIR hyperintense foci are noted in bilateral cerebral white matter. No diffusion restriction.
The orbits, paranasal sinuses and mastoid air cells are clear.
No bony abnormality is seen. The craniocervical junction is normal.
Conclusion:
Small cavernoma in the right temporal operculum with associated developmental venous anomaly (DVA). No evidence of any recent haemorrhage.
