1 Figure 1 MRI of both patients with IgG4-HP and spinal cord arteriography of the first patient
MRI of both patients with IgG4-HP and spinal cord arteriography of the first patient (A) Multiple T2 hyperintense signals (white arrows) (A.a) all enhanced after gadolinium injection (A.b) of the posterior half of the cervico-thoracic spinal cord. T2 hypointense signal of the posterior subarachnoid space from C5 to D3 suggesting a dural fistula (red arrow) (A.c), confirmed by medullary arteriography (A.d) with opacification of a venous peloton opposite the meninge of the left lateral part of the dural sheath corresponding to the medullary veins visible on MRI. (B) Intra-ductal, intra-dural, postero-median, polylobulated tumor lesion, well-defined, in T1 isointense signal (B.a), intensely and homogeneously enhanced after injection of gadolinium (B.b), T2 hypointense signal (B.c), next to D2-D3 realizing a mass effect on the spinal cord. There is an extensive intramedullary edema supra and under-lesion (B.d). (C) Bi-frontal meningeal thickening enhanced by gadolinium invading the sheaths of optic nerves and cavernous sinuses (white arrows) (C.a and c). T2/FLAIR hyperintense signal of the left optic nerve testifying to radiologic optic neuritis, white arrows (C.b d). FLAIR = fluid attenuated inversion recovery. Michaël Levraut et al.
