Female, 40 years old, with leg weakness, preoperative evaluation for surgical planning. T2 hyperintensity and gyral thickening is again seen involving the left paracentral lobule. On comparison with the prior examination, there has been some progression of this signal abnormality which extends further laterally into the left precentral gyrus. Sequelae of prior biopsy are noted including small cystic cavities along the biopsy trajectory and artifact related to the biopsy marker. Scattered foci of enhancement within the lesion are nonspecific and may be postoperative in nature. Incidental note is made of a developmental venous anomaly along the right marginal sulcus. No new lesions are detected. The ventricles are normal in size and morphology.
Redemonstration of a lesion and/or lesional edema in the left paracentral lobule which has mildly expanded when compared to the prior exam.
