Female, 40 years old, with cavernous malformation, evaluate for change. A bilobed heterogeneous lesion is again seen centered on the right basal ganglia. As before, the lesion is heterogeneously T2 hyperintense internally and contains scattered locules of T1 hyperintensity. On postcontrast imaging, the components of the lesion which are not intrinsically T1 hyperintense do show contrast fill-in. The lesion measures approximately 35 x 24 mm when measured similarly to the prior examination showing no significant interval change in size. There is a thin rim of surrounding susceptibility effect, but no significant edema in the adjacent parenchyma. The lesion causes local mass effect with perhaps partial effacement the right frontal horn and slight encroachment upon the third ventricle, similar to prior. The ventricular system is otherwise unremarkable. No additional intracranial lesions are seen. No other pathologic enhancement is identified. Scattered punctate foci of FLAIR hyperintensity elsewhere in the cerebral hemispheres are nonspecific and unchanged.
No significant change in size or morphology of a presumed cavernous malformation centered on the right basal ganglia.
