Small cavernous malformation

Small cavernous malformation, best visualized on susceptibility weighted imaging (SWI). Detection of this small, medial, posterior frontal cavernous malformation is poorest on FLAIR, of the presented scans, and best on SWI. Multiple research articles in the scientific literature have shown that SWI is more sensitive for detection of cerebral cavernous malformations than T2-weighted gradient echo imaging, with studies conducted predominantly in multifocal/familial cases such as this patient (who manifested multiple other lesions at different anatomic levels).
