Microscopic polyangiitis (MPA) is an idiopathic autoimmune disease characterized by systemic vasculitis. While the lungs and kidneys are the major organs affected by MPA, it is known to involve multiple organ systems throughout the body. Temporal artery involvement is a very rare finding in MPA. This report presents a patient whose initial presentation was consistent with giant cell arteritis but was ultimately found to have microscopic polyangiitis. It highlights the importance of considering alternative types of vasculitis in the differential diagnosis for patients with atypical temporal artery biopsy findings.
显微镜下多血管炎（MPA）是一种以系统性血管炎为特征的特发性自身免疫性疾病。虽然肺和肾是受MPA影响的主要器官，但已知它可累及全身多个器官系统。颞动脉受累在MPA中是非常罕见的表现。本报告介绍了一名患者，其最初表现与巨细胞动脉炎一致，但最终被诊断为显微镜下多血管炎。它强调了在对颞动脉活检结果不典型的患者进行鉴别诊断时，考虑其他类型血管炎的重要性。
