Osteomyelites, bone infections of a hematogenous origin, are rare in the pelvis (2.3%) and are extremely rare in the ischium. Ischiatic osteomyelitis is usually found in children and adolescents, but has rarely been described in adults. The clinical presentation varies and the diagnosis is based on magnetic resonance imaging (MRI). The most frequently isolated germ is the staphylococcus, while Escherichia coli has been found in a few cases. We report a case of osteomyelitis from E. coli in a 46-year-old woman revealed by persistent fever. The point of entry was a septicemia from gastrointestinal origin, related to colon polyps. The clinical picture was also complicated by an antiphospholipid antibody syndrome (superior mesenteric vein and splenomesenteric branch thrombosis). The course was favorable thanks to appropriate antibiotic treatment and surgical debridment of the infection.
骨髓炎，即血源性骨感染，在骨盆中较为罕见（2.3%），坐骨处则更为罕见。坐骨骨髓炎通常见于儿童和青少年，但在成人中很少见。临床表现多样，诊断基于磁共振成像（MRI）。最常分离到的细菌是葡萄球菌，而大肠杆菌在少数情况下被发现。我们报告了一例 46 岁女性由大肠杆菌引起的骨髓炎，其表现为持续性发热。感染源为胃肠道来源的败血症，与结肠息肉有关。该患者还并发抗磷脂抗体综合征（肠系膜上静脉和脾分支血栓形成），使临床表现更为复杂。由于给予了适当的抗生素治疗和手术清创，该患者的病程良好。
