Granulomatosis (Wegener's granulomatosis) with polyangiitis presented as pulmonary manifestation: a case report

Pulmonary vasculitis can be the manifestation of several systemic illnesses such as primary systemic vasculitis, collagen vascular diseases, and systemic diseases associated with autoantibodies. It may be associated with granulomatous, eosinophilic, lymphoplasmacytic and neutrophilic inflammatory diseases. In this case report, we describe a 22‐year‐old female presented with intermittent fever, sweating and shivering, haemoptysis, sore throat, shortness of breath, fatigue, loss of appetite, nausea, non‐projectile vomiting, dizziness, and dark coloured urine. The diagnosis of granulomatosis with polyangiitis was made utilizing biochemical and radiological tests. Several pharmacological therapies were tried including rituximab. The patient made a good recovery and was discharged home after 12 days of hospitalization. The knowledge of the main radiographic and computed tomography (CT) scan findings, in association with clinical and laboratory data, often enables non‐invasive diagnosis of pulmonary vasculitis. The diagnosis of vasculitis is often delayed because several other disorders may mimic the same clinical manifestations; therefore, the knowledge of the main radiographic and high‐resolution computed tomography (HRCT) findings, in association with clinical, laboratory, and serum data, often enables non‐invasive diagnosis of pulmonary vasculitis.
