title: MRI of cerebral rheumatoid pachymeningitis: report of two cases with follow-up.
abstract: We report the clinical and neuroradiological features of cerebral rheumatoid pachymeningitis with 1 year follow-up in two patients. MRI of the head enabled noninvasive diagnosis of both the meningeal abnormality and its complications, consisting of hypertensive hydrocephalus and superior sagittal sinus thrombosis, respectively. Dural sinus thrombosis, very uncommon in rheumatoid arthritis, was confirmed by phase-contrast MRA. Worsening of the pachymeningitis at follow-up was observed in both patients despite regression or stability of the clinical picture and long-term therapy.
