Immunoglobulin G4-related spinal pachymeningitis: A case report

Figure 1 Brain magnetic resonance imaging on hospital day 1 and follow-up brain magnetic resonance imaging on hospital day 19. A-E: Brain magnetic resonance imaging on hospital day 1. Diffusion weighted image showing focal infarction in the bilateral parietal lobes (A), left frontal lobe (B), right occipital lobe (C-E); F-J: Follow-up brain magnetic resonance imaging on hospital day 19. Right parietal lobe (F and G), left parietal lobe (H), left frontal lobe (I), left occipital lobe (J).

Figure 2 Spine magnetic resonance imaging on hospital day 45 and follow up spine magnetic resonance imaging on hospital day 67. A: The T1 weighted image showed a low signal intensity in the lesion area; B: The T2 weighted image showed a mixture of low and high signal intensities in the lesion area; the range was between the ninth thoracic vertebra and the first lumbar vertebra, indicating immunoglobulin G4-related spinal pachymeningitis. The transverse view showed that the lesion was more involved on the left side.
