Female, 61 years old, with a right-sided low-grade glioma. Surveillance imaging. An oval T2 hyperintense lesion is again seen within the right centrum semiovale, just above the body of the right lateral ventricle. This lesion continues to measure approximately 21 x 13 mm in the axial plane and shows no significant change from multiple prior exams. As before, the lesion shows evidence of prior biopsy. No associated pathologic enhancement is seen, and the lesion correlates to low rCBV.Elsewhere no new or significant areas of signal abnormality are seen. A few additional scattered foci of white matter T2 hyperintensity are unchanged and nonspecific. No evidence of parenchymal edema or mass effect is detected. No pathologic parenchymal or extra-axial enhancement is seen. No findings to suggest intracranial hemorrhage or any abnormal extra-axial fluid are evident. The ventricles are normal in size and shape. Partially empty sella is noted incidentally.A subcentimeter nonspecific enhancing focus within the left frontal bone is unchanged. Marrow signal characteristics are otherwise unremarkable.
No significant interval change in the size or appearance of a non-enhancing lesion in the right centrum semiovale.
