Other specified types of non-hodgkin lymphoma, extranodal and solid organ sites [C85.89], Reason for Study: ^Reason: evaluate for etiology of double vision History: cocern for recurrence of orbital lymphoma Orbit MRINo evidence of recurrence mass within the orbit. There is no evidence of abnormal enhancement.The globes, optic nerves, extraocular muscles and retroglobal spaces are symmetric and normal. The lacrimal glands are normal. There is no evidence of signal abnormality, mass, or abnormal contrast enhancement.  Brain MRIThere is no evidence of acute ischemic or hemorrhagic lesion.Focal encephalomalacia on the left frontal lobe is again seen, unchanged.The ventricles, sulci and cisterns are symmetric and unremarkable. The gray-white matter differentiation is normal. There is no mass, mass effect, edema, midline shift, intra- or extra-axial fluid collection, hemorrhage, restricted diffusion/acute ischemia or abnormal contrast enhancement. The midline structures and cranial-cervical junction are normal. Normal flow voids are identified in the major intracranial vessels. The mastoid air cells are clear.Mucosal thickening are seen within the frontal sinus and ethmoid sinus. Empty sella is noted.Lumbar spine MRIFor the purpose of this dictation, the lowest visualized intervertebral disc space is labeled L5-S1. There is evidence of left side laminectomy at the level of L34, L4-5 and L5-S1.Soft tissue fluid collections are seen from L23 to L45 which likely represent postoperative changes.There is normal lumbar lordosis. The spine alignment is anatomic. The vertebral body height is preserved. The signal of the visualized cord is normal.The conus medullaris terminates at the L1 level. Degenerative changes are specified by the intervertebral level as follows: T12-L1: Disc desiccation. No neuroforaminal narrowing or spinal stenosis. L1-L2: Broad-based disc protrusion central to left which abuts thecal sac. However, no significant neuroforaminal narrowing or spinal stenosis. L2-L3: Disc desiccation with diffuse bulging of disc. No neuroforaminal narrowing or spinal stenosis. L3-L4: Left sided total laminectomy status. Diffuse bulging of disc with bilateral ligamentum flavum thickening results mild to moderate spinal canal stenosis. L4-L5: Left sided total laminectomy status. Diffuse bulging of disc with bilateral ligamentum flavum thickening results moderate to severe spinal canal stenosis. L5-S1: Left sided total laminectomy status. Diffuse bulging of disc with left side lateral recess stenosis.
1. No evidence of recurrence orbital tumor or abnormal enhancement within the orbit.2. No evidence of acute ischemic or hemorrhagic lesion or abnormal enhancement of the brain.3. Unchanged left frontal encephalomalacia since prior scan.4. Postoperative status, left side laminectomy from L3-4 to L5-S1.5. Degenerative changes of lumbar spine including various degree spinal canal stenosis at the level of L3-4, L4-5 and left lateral recess stenosis at L5-S1.
