Two clinical cases of granulomatosis with polyangiitis with isolated otitis media and mastoiditis

摘要

Granulomatosis with polyangiitis (GPA) is characterised by granulomatous necrotising inflammatory lesions of the upper and lower respiratory tract, often associated with pauci-immune glomerulonephritis. The diagnosis of granulomatosis with polyangiitis is made according to the classification criteria of the ACR criteria for granulomatosis with polyangiitis. We present two cases of granulomatosis with polyangiitis limited/localised form. The common feature between two clinical cases were not sufficient criteria for a definite diagnosis at the beginning. In both cases the clinical presence was otitis media with acute mastoiditis, peripheral facial nerve palsy, and severe headache. Early diagnosis and treatment of patients with granulomatosis with polyangiitis define favourable prognosis. On the other hand, the treatment of granulomatosis with polyangiitis (corticosteroids and immunosuppressive therapy) has various side effects, and the “ex juvantibus” therapy is hazardous.
