Pseudomyogenic hemangioendothelioma (PMH) of bone is a very rare tumor and frequently presents at multiple locations. PMH is difficult to diagnose by imaging and histopathologic features. Various and partially discordant imaging findings have been reported in case reports and small case series. We report a case of a 63-year-old man with PMH isolated to the sacrum, presenting with chronic intermittent buttock pain that was incidentally identified on imaging for acute pancreatitis. We believe that learning about PMH of bone will help to include this disease in the differential diagnosis of lytic lesions of the sacrum. Becoming aware of the various and sometimes discordant imaging findings of this rare entity is important and helpful for radiologists, pathologists, and orthopedic surgeons.
骨假肌源性血管内皮瘤（PMH）是一种非常罕见的肿瘤，常呈多部位发病。PMH很难通过影像学和组织病理学特征进行诊断。在病例报告和小病例系列中已报道了各种且部分不一致的影像学表现。我们报告一例63岁男性，其PMH仅累及骶骨，表现为慢性间歇性臀部疼痛，在因急性胰腺炎进行影像学检查时偶然发现。我们认为，了解骨PMH将有助于将该疾病纳入骶骨溶骨性病变的鉴别诊断中。认识到这种罕见实体的各种有时不一致的影像学表现，对放射科医生、病理科医生和骨科医生来说很重要且有帮助。
