[Mononeuritis multiplex as initial manifestation of systemic granulomatosis]

We report two young patients with a painful and rapidly progressive polyneuropathy of the mononeuritis multiplex type confiding them to bed. Extensive investigations led to the diagnosis of a granulomatosis in both: Churg-Strauss allergic granulomatosis in one and Wegener's granulomatosis in the other. The importance and frequency of peripheral nervous system manifestations in the presenting clinical pattern of a systemic granulomatosis and vasculitis are discussed. Their proper recognition with regard to available effective therapeutic measures is stressed.
