Abstract
A case of hypertrophic cranial pachymeningitis with an unusual and misleadi ng 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 o f dural sinuses showed interestingly signal-void appearance on spin-echo im ages which could readily be interpreted as being patent sinuses.
