Findings:
The SWI sequence demonstrates widespread focal regions of susceptibility induced signal loss involving bilateral cerebral and cerebellar hemispheres as well as the pons and the left thalamus, ranging in different sizes from microscopic to approximately 1.2 cm. The largest lesion is located in the right middle cerebellar peduncle showing characteristic popcorn appearance with a dark rim of signal loss. No associated perifocal oedema.
Several, punctiform foci of T2/flair hyperintensity are noted in bilateral cerebral white matter, in keeping with mild small vessel ischaemic disease. No diffusion restriction.
The ventricles and sulcal spaces are within normal limits. The midline structures are normal with no midline shift.
The pituitary gland is normal.
The orbits, paranasal sinuses and mastoid air cells are clear. No bony abnormality is seen.
Impression:
Known multiple cavernoma syndrome without evidence of any acute bleed.
