26 years Male (DOB:1/25/1990)Reason: pre op planning, needs fiducials. History: pre op planningPROVIDER/ATTENDING NAME: KRUPA G ANDALKAR BAKHTIAR V. YAMINI There are fiducial markers in place. There is a couple enhancing lesions one in the present in the left cingulate gyrus extending towards the corpus callosum which appears smaller compared to prior exam. It measures approximately 30 x 16 mm axial dimensions and is associated with T2 white matter signal hyperintensity surrounding it compatible with vasogenic edema. On the prior exam measured 25 x 52 mm. Another lesion is present in the left precuneus measuring approximately 11 x 17 mm along its enhancing portion also associated with T2 signal hyperintensity along the adjacent white matter suggestive of vasogenic edema. On the prior exam measured 20 x 15 mm.The patient status post left-sided craniotomy.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.There are enhancing tumors within the left cingulate gyrus and corpus callosum and within the left precuneus of the parotid left parietal lobe. This compatible with a neoplasms. One possibility based on the enhancement pattern is that this represents lymphoma. Other possiblities include demyelination and granulomatous disorder. The enhancing components appear smaller when compared to the prior exam suggesting status post steroid use or diagnosis other than lymphoma. 2.Examination was performed for the purposes of stereotactic guidance during surgery.
