56 years Female (DOB:1/26/1960)Reason: preop planning for tumor biopsy History: preop planningPROVIDER/ATTENDING NAME: BAKHTIAR YAMINI BAKHTIAR YAMINI There is a ring-enhancing mass present in the right frontal lobe measuring 30 x 30 mm axial dimensions. This is centered in the right inferior frontal gyrus. Another several ring-enhancing lesions are present in the right superior frontal gyrus the largest one measuring 15 x 11 mm axial dimensions. Another lesion is present in the right temporal lobe measuring 20 x 18 mm axial dimensions. These lesions are surrounded by T2 signal hyperintensity compatible with vasogenic edema pattern.There is T2 signal hyperintensity present within the right middle cerebral peduncle extending to the pons.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Exam was performed for the purpose of stereotactic guidance during surgery. It is therefore limited. There are ring-enhancing right frontal lobe masses present and another mass in the right temporal lobe. These are suspicious for neoplasms, however, further characterization2.The lesion in the right midbrain and pons is nonspecific.
