78 years Female (DOB:3/13/1938)Reason: preop planning for biopsy History: preopPROVIDER/ATTENDING NAME: BAKHTIAR YAMINI BAKHTIAR YAMINI There is redemonstration of a hemorrhagic lesion with a ring enhancement located at the right occipital lobe which currently measures 8 x 6 mm coronal dimensions and 8 x 6 mm axial dimensions. It has the same measurements on the prior exam from 6/17/2016.There is redemonstration of a extra-axial lesion along the left tentorial leaf adjacent to the left vermis which measures 6 mm and is unchanged prior exam. A microhemorrhage identified on the prior exam in the right cuneus is not identified on the current exam. It was never associated with any contrast enhancement.There is a mild to moderate degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.The visualized portions of the paranasal sinuses demonstrate partial opacification of the left maxillary sinus which is stable compared to the prior exam.. The visualized portions of the mastoid air cells are opacified. There are a few are opacities in the left mastoid air cells. Mastoid opacification is stable compared to the prior exam The visualized portions of the orbits are intact. The eyeball lenses are thin.
1.There is redemonstration of a right occipital lobe hemorrhagic enhancing lesion as well as the left tentorial based lesion which are stable compared to the prior exam. These are suspicious for metastatic disease. The left tentorial leaf extra-axial lesion could also represent a meningioma which statistically would be more likely.2.Periventricular and subcortical white matter lesions of a mild to moderate degree are nonspecific. At this age they are most likely vascular related. 3.Examination was performed for the purposes of stereotactic guidance during surgery.
