IgG4-related aortitis is an inflammatory condition of the aorta, characterized by aortic wall thickening and periaortic soft-tissue involvement. Therefore, this condition can mimic an aortic intramural hematoma (IMH), due to similar radiological findings. We hereby report the case of an IgG4-related aortitis misdiagnosed as an IMH, associated with cerebral hemorrhage, possibly due to cerebral vascular system involvement.

如何模拟A型壁内血肿：脑出血相关的IgG4相关性主动脉炎一例

IgG4 相关的主动脉炎是主动脉的一种炎症性疾病，其特征是主动脉壁增厚和主动脉周围软组织受累。因此，由于类似的放射学发现，这种情况可以模拟主动脉壁内血肿 (IMH)。我们在此报告一例 IgG4 相关主动脉炎被误诊为 IMH 的病例，该病例与脑出血相关，可能是由于脑血管系统受累。
