64 years Female (DOB:4/28/1952)Reason: 64 year old with primary CNS lymphoma who is s/p consolidation chemotherapy with cytarabine on 11/27. History: primary CNS lymphomaPROVIDER/ATTENDING NAME: KENNETH S COHEN EVERETT E VOKES The patient status post left parietal craniotomy for removal of a neoplasm. There are some encephalomalacia and susceptibility effect present in the underlying left parietal lobe which extends to the left postcentral gyrus and the superior parietal lobule. This appearance is stable compared to the previous exam.There is redemonstration of a right paramedian mass adjacent to the right cuneus and superior sagittal sinus which extends into the superior sagittal sinus. It measures 13 x 9 mm axial dimensions and has not changed significantly compared to the prior exam.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 demonstrate partial opacification of the right sphenoid sinus. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
1.Status post left parietal craniotomy for removal of a neoplasm. There is no evidence for local recurrence.2.Right paramedian extra-axial mass extending into the superior sagittal sinus is stable compared to the prior exam. Venography may help further assess superior sagittal sinus involvement. Differential considerations include angioma as well as lymphoma.
