Otorrinolaringological manifestations of granulomatosis with multiple Mononeuropathy and Poliangeiacute;tis: A diagnostic challenge

Abstract

Granulomatosis with Polyangiitis (GPA), previously known as Wegener's Granulomatosis, is an entity with great potential to trigger multiple manifestations in the head and neck region. The initial presentation form and its non-specific characteristics is usually misdiagnosed and confused with different entities. Within the manifestations of peripheral neuropathy, multiple mononeuritis is more common, while central nervous system involvement is more rare. We address an interesting case of granulomatosis with polyangiitis that manifested itself with multiple cranial nerve involvement mononeuritis.
