Multiple cerebral cavernous malformations. The surgical cavity in the posterior right temporal lobe is unchanged nor is the susceptibility effect along the surgical margin or the minimal adjacent parenchymal T2-hyperintensity. The lobulated T2-hyperintense lesion involving the left frontal lobe, which shows susceptibility effect, is unchanged since January 2016 though minimally increased compared to the March 2015 examination. The multiple other cerebral and cerebellar foci of susceptibility effect were also present previously. There is no mass-effect, midline shift or abnormal intracranial contrast enhancement. The ventricles are unchanged. The major intracranial vascular flow voids are otherwise preserved.There is mucosal thickening in the left ethmoid sinuses. The orbits are grossly unremarkable. Postoperative changes are present around the right parieto-occipital-temporal craniotomy.
1.Unchanged right posterior temporal postoperative findings.2.Multiple cerebral and cerebellar cavernous malformations are unchanged since January 2016. However, the left frontal T1-hyperintense cavernous malformation is slightly larger than in March 2015. No new focus of susceptibility effect to indicate the development of a new lesion.
