Pachymeningitis in Granulomatosis with Polyangiitis: A Case Report and a Review of the Literature

Central nervous involvement, mainly with symptoms of cranial neuropathies, occurs in 2–8% of patients with granulomatosis with polyangiitis (GPA). Meningeal involvement, with persistent and severe headache as main manifestation and abnormal thickening and enhancement of the dural mater on postcontrast magnetic resonance imaging, is extremely rare. We present a case of pachymeningitis due to limited GPA, providing simultaneously a literature review.
