Hypertrophic cranial pachymeningitis involving dural sinuses: a pseudo signal-void appearance on MRI.
A case of hypertrophic cranial pachymeningitis with an unusual and misleading manifestation is reported. CT detected calcified tentorium and superior sagittal sinus. MR imaging and MR angiography depicted tentorial thickening as well as occlusion of all major dural sinuses. Fibrocalcific occlusion of dural sinuses showed interestingly signal-void appearance on spin-echo images which could readily be interpreted as being patent sinuses.
