초록

혈관염은 혈관벽의 염증을 특징으로 하는 드문 전신 질환으로 간혹 미만성 폐출혈이나 급성사구체신염으로 생명을 위협하기도 한다. 원인을 알 수 없는 일차성 혈관염도 있지만 자가면역 질환이나 약물, 감염, 종양 등 수많은 원인들에 의해 발생하는 이차성 혈관염도 있으며 분류가 복잡하고 명확한 진단검사가 없어 진단에 어려움이 있다. 또한 다양하고 비특이적인 증상과 징후 및 검사 소견을 보여 혈관염의 진단에는 임상양상, 영상 검사, 자가항체 검사, 병리소견 등 여러 가지 결과를 종합하는 것이 필수적이다. 이 종설에서는 혈관염의 분류와 진단에 중요한 증상 및 징후, 특징적으로 폐를 침범하는 대표적인 폐혈관염의 영상 소견과 감별진단, 그리고 새로운 혈관염 분류를 위한 국제적 연구인 Diagnostic and Classification Criteria in Vasculitis에 대해 소개하고자 한다.

Vasculitis is a systemic disease, characterized by inflammation of the vascular wall. Although rare, it is sometimes life-threatening due to diffuse pulmonary hemorrhage or acute glomerulonephritis. Besides primary vasculitis, whose cause is unknown, numerous conditions such as autoimmune diseases, drugs, infections, and tumors can cause secondary vasculitis. Vasculitis displays various non-specific symptoms, signs, and laboratory findings; hence, diagnosis of the disease requires integration of various results including clinical features, imaging findings, autoantibody tests, and pathological findings. In this review, we have discussed the clinical, radiologic, and pathological features of vasculitis. Further, we elaborated the imaging findings and differential diagnosis of typical vasculitis that frequently involves the lung and introduced a new international classification of vasculitis, the Diagnostic and Classification Criteria in Vasculitis.
