Neoplasm of unspecified behavior of brain [D49.6], Reason for Study: ^Reason: brain lesion. Preop planning for biopsy History: headaches Extra-axial mass likely represent meningioma on the anterior aspect of falx do not show any significant interval change in terms of MR characteristics as well its size (T:24.4 mm x CC:27.2 mm x AP:30.7 mm).Dural sinuses specialist superior sagittal sinus appears to be intact.Subtle high signal intensity on the left frontal lobe on T2 and FLAIR imaging, does not show any significant interval change since prior scan.The ventricles, sulci and cisterns are symmetric and unremarkable. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The paranasal sinuses and mastoid air cells are clear.
No change of anterior falx meningioma in terms of size and MR characteristics as well as left inferior frontal lobe white matter lesion since prior scan.
