Introduction: Wegener's granulomatosis is a systemic vasculitis which, in its classical form, is characterized by involvement of the superior and inferior respiratory tract and the kidneys. The vasculitis may be multisystemic. Ophthalmic and neurological involvement are common (22% and 54% of those affected respectively). When considering involvement of the nervous system, the commonest finding is peripheral neuropathy, particularly in the form of multiple mononeuritis. Meningeal involvement is exceptional.
Clinical case and conclusions: We present a case of Wegener's granulomatosis with meningeal involvement, studied using CT and MR. The findings using imaging techniques are described, and conditions which should be considered in the differential diagnosis are discussed.
