波特氏浮肿瘤 (PPT) 是一种复杂的额窦炎，也称为额骨骨髓炎和局限性骨膜下脓肿。早期诊断和立即积极治疗对于防止严重的神经系统后遗症是必要的。在此，我们报告一例患有波特氏浮肿瘤的病例，患者为一名原本健康的 13 岁女孩，头痛加剧，额骨肿胀，并伴有呕吐和发烧。磁共振成像显示额骨骨髓炎。通过内窥镜检查发现异物并取出，然后进行 6 周的肠外和肠内抗生素治疗，所有症状均得到缓解。关于外伤、昆虫叮咬或鼻内异物的完整病史对于治疗来说至关重要。建议正确诊断，并对耳鼻喉 (ENT) 进行全面检查以排除异物。© 作者。

Pott's Puffy tumor (PPT) is a complicated frontal sinusitis that is also described as frontal bone osteomyelitis and a localized sub periosteal abscess. Early diagnosis and immediate active treatment are necessary to prevent severe neurologic sequelae.Here, we report on a case of Pott's puffy tumor in a previously healthy 13-year-old girl with a worsening headache and swelling of the frontal bone accompanied by vomiting and fever. Magnetic resonance imaging revealed osteomyelitis of the frontal bone. A foreign body was discovered and removed via endoscopy which was then followed by 6 weeks of parenteral and enteral antibiotic therapy, resulting in resolution of all symptoms.A complete history in terms of trauma and insect bite or foreign body in the nose is paramount for a correct diagnosis, and performing a full examination of ear, nose and throat (ENT) to rule out a foreign body is advised.© The Author(s).
