72 years Male (DOB:6/28/1943)Reason: CNS lymphoma History: compare with previous MRI; s/p treatmentPROVIDER/ATTENDING NAME: CHADI NABHAN CHADI NABHAN The patient is status post left frontal lobe biopsy. A tract is identified coursing through the left frontal bone into the left frontal lobe and into the lesion There are punctate foci of microhemorrhage in the left frontal lobe. There is a heterogeneous lesion on FLAIR imaging along the left orbital gyrus without contrast enhancement present at this time. There is surrounding signal hyperintensity on FLAIR imaging centered in the left inferior frontal lobe which is a stable.A 3mm hemorrhagic focus is identified in the right frontal lobe which is stable. The FLAIR signal hyperintensity currently measures 18 x 10 mm. It has no significant contrast enhancement.There is a mild degree of periventricular and subcortical punctate hyperintense white matter lesions present identified on the FLAIR and T2 images.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. The eyeball lenses are thin.
1.The patient is status-post left frontal lobe biopsy2.There is a left frontal lobe lesion centered in the left orbital gyrus which is stable since the prior exam from February. Most likely this represents posttreatment change.3.A smaller lesion in the right frontal lobe is also stable.
