机化血肿是出血周围纤维化组织的慢性状态。1917年首次报道了上颌窦血肿引起的肿块病变，临床上从包裹的血液和局部攻击行为等特征中创造了术语“血沸”。随后，其他人报道了具有类似外观和临床过程的病变，现在，在日本，血液沸腾被用作此类病变的临床术语。可能使患者易于形成血肿的因素各不相同，并且肿块的发病机制仍然不确定。病变主要由机化血肿组成，无论其起源如何。我们报告2例上颌窦血肿，其影像学表现不寻常，并将其与病理组织学表现相关联。
An organized hematoma is a chronic state of fibrotic tissue surrounding a hemorrhage. A mass lesion resulting from hematoma in the maxillary sinus was first reported in 1917, and the term, "blood boil," was clinically coined from such features as encapsulated blood and locally aggressive behavior. Subsequently, others have reported lesions with a similar appearance and clinical course, and now, in Japan, blood boil is used as a clinical term for such lesions. Factors that may predispose a patient to hematoma formation vary, and the pathogenesis of the mass is still uncertain. The lesions are mainly composed of an organized hematoma, regardless of their origin. We present 2 cases of organized maxillary sinus hematomas that have unusual radiologic findings and correlate these findings with the histopathoiogic findings.
