This article aims to report a case of a patient with atypical nodular scleritis as the initial manifestation of granulomatous polyangiitis (Wegener), mimicking a case of tuberculosis. The patient presented ocular hyperemia and lower progressive visual acuity for 1.5 years, followed by eye pain for two months. The patient had subpleural nodules with soft tissue density, increased pulmonary lymph nodes and discrete bilateral pleural thickening, with negative alcohol-resistant acid bacilli (BAAR). The histological diagnosis revealed a granulomatous vasculitis suggestive of non-infectious vasculitis (granulomatous polyangiitis). Cyclophosphamide pulse therapy was initiated.
