Male, 71 years old, with multiple sclerosis, assess for progression. Multiple T2 hyperintense lesions are redemonstrated predominantly within the corpus callosum and periventricular white matter of the cerebral hemispheres. There may be a few punctate lesions within the pons, but this is equivocal. Accounting for substantial differences in technique on the prior comparison examination, no definite change is seen in lesion size or number. These lesions demonstrate moderate T1 hypointensity which is also unchanged from prior. No definite lesional enhancement is seen.No edema or mass effect is detected. No abnormal extra-axial collections. Volume of the corpus callosum and brain is preserved and typical for the stated age. The ventricular system is stable and normal in size. Incidental note is made of edema within the right mandibular condyle, and enhancement of the right temporomandibular joint capsule.
1.Multiple white matter lesions are redemonstrated compatible with multiple sclerosis. Accounting for substantial technical differences on the comparison examination, no definite or significant interval change in lesion size or number is seen. No enhancing lesions are evident to suggest active demyelination.2.Findings are seen which may reflect right TMJ arthropathy.
