38 year-old female with cerebral cavernous malformations, annual evaluation for change in size/number of lesions The CSF spaces are appropriate for the patient's stated age with no midline shift. Redemonstrated is a right frontal lobe lesion with a heterogeneous appearance on T1/T2 with a blooming effect on susceptibility imaging. The lesional nidus appears slightly retracted, with resolution of previously demonstrated fluid/heme levels. The lesion as measured between hemosiderin stained borders is unchanged. There is no perilesional edema.There are a few foci of T2 hyperintensity, the most prominent of which is within the left superior frontal gyrus subcortical white matter. Smaller findings are also noted in the right posterior lateral frontal lobe. At the time, these lesions do not demonstrate discrete susceptibility abnormality, and are stable in appearance.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.Other than a few scattered mucus retention cysts, the visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Stable right frontal cavernous malformation without perilesional edema.2.Stable foci of T2 hyperintensity.
