Chest X-ray examination demonstrated pneumonia and nodular shadow, pleurisy or pleural effusion. Can be violations of the nervous system, if a headache, diplopia, paranoia, mental disorders, cerebral thrombosis and even paralysis, dysphagia, sensory and / or motor function disorders. Heart damage is myocardial infarction, cardiac rhythm disorders and pericarditis. Ischemic renal cortex may have serious high blood pressure. The most common systemic vasculitis of the ocular inflammation manifested as the outer sclera and retinal hemorrhage. Vice Clonorchis and painful swelling of the testicles may be a manifestation of vasculitis. Diagnosis of systemic vasculitis, including renal biopsy and direct immunofluorescence assay
