Reason: H/O DLBCLymphoma with CNS involvement s/p 3/5 cycles of MTR now with mental status changes History: NHL with Mental status chenges Since the prior exam a mass centered along the anterior commissure has enlarged. It previously measured approximately 20 by 10 mm axial dimensions and now measures 36 x 33 mm sagittal dimensions. It infiltrates into adjacent basal ganglia, septum pellucidum, hypothalamus and bulges into the suprasellar cistern, lateral ventricles and third ventricle. The internal cerebral veins are displaced posteriorly. The anterior septal veins are splayed. The right A1 segment is displaced inferiorly The mass is eccentric towards the right side. A small focus of susceptibility along the right half of the lesion likely represents hemosiderin from the biopsy site.A burr hole is present along the right frontal bone.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.Since the prior exam the patient's midline mass compatible with the diagnosis of lymphoma has enlarged as detailed above.
