 Long-standing bilateral leg pain and swelling. History of wind farm exposure. 2020 April Fools case 这个病例来源于Radiopaedia的愚人节病例，该病例并非真实，请注意以上声明，因为我们将要开始“谈学术”了。如果真信了我们的讨论，鼎湖影像将不对此负责 结果公布：Resonance imparted periostitis (RIP) 共振性骨膜炎 Case DiscussionImages pathognomonic of resonance imparted periostitis (RIP), in this case secondary to wind turbine exposure rather than the more common nautical wave exposure responsible for bow legged sailors. The 15cm wavelength of undulation matches the low frequency output of modern wind turbines. 根据影像特征该病例可诊断为共振性骨膜炎，该病例继发于风力涡轮机暴露而非航海雷达声波的暴露。15厘米的波长与风力涡轮机的低频输出相匹配。 This patient self-presented concerned he may have RIP after seeing recent reports on TV and social media. He has lived near a wind farm for over 20 years and experienced progressive bilateral leg pain over 2 to 3 years. On examination, movement and strength were normal. Hard, moderately-tender, subcutaneous undulations over his shins were palpable. Radiographs showed classic sine wave cortical deformity and active resonant periostitis. 患者自述其最近在电视和社交媒体上看到相关报道，担心自己可能患有共振性骨膜炎可能。患者在风电场附近生活了20多年，近2-3年，渐进性双侧下肢腿痛。查体运动和肌力正常。其小腿可触及坚硬的、中等柔软的皮下波浪性改变。X线片显示典型的正弦波皮质畸形和活动性共振性骨膜炎。 While the prevalence of RIP has reduced dramatically over the last 100 years with changes in maritime behavior, it is now undergoing a resurgence due to the proliferation of clean energy. The deformity is most prominent in the lower limbs, supporting the theory that direct transmission of mechanical impulses via the ground is the causative agent. Milder deformity may be seen more cephalad in the skeleton due to dissipation of the oscillatory energy. 尽管100年来，由于海洋行为的变化，RIP的发病率明显降低。但由于清洁能源的广泛应用，该病又开始盛行。下肢畸形最为突出，病因可能是机械脉冲通过地面直接传递。由于振荡能量的耗散，头侧的骨骼畸形较轻 。 Case reports suggest differing osseous wavelengths depending on the types of wind turbines in use in different parts of the world. For example, British people with the disease tend to have a wavelength close to 12 cm whereas Dutch people (where the turbine association was first described) have a wavelength closer to 18 cm as their wind turbines are taller with longer blade lengths. 病例报告表明，不同的骨性波长取决于世界不同地区使用的风力涡轮机的类型。例如，患有这种疾病的英国人的波长往往接近12厘米；而荷兰人(他们的涡轮机协会首先被描述)的波长接近18厘米，因为他们的风力涡轮机更高，叶片更长。 A strong association has emerged between RIP and renal colic, with ureteric stones forming ~15cm and ~30cm from the vesicoureteric junctions; at nodes of standing waves that travel through the ureter. Patients have also reported an uncommon form of vertigo when supine, where they describe the room spinning in the vertical plane, rather than the more common horizontal spinning room encountered in acute ethanol poisoning. RIP与肾绞痛之间存在较强的相关性，约15cm ~30cm的输尿管结石形成于膀胱输尿管交界处。患者还表现为一种少见的仰卧时眩晕，他们描述的是在垂直平面上旋转，而不是急性酒精中毒时更常见的水平旋转。 Importantly, a social media-fueled hoax suggesting that this condition is due to Magnetic Resonance Imaging scanners has no factual basis and has led to unwarranted concern over the use of 3 T and 7T MRI. The Radiological Action Group of Scotland (RAGS) recently launched a highly successful and entertaining video campaign dispelling any link between MRI and RIP entitled “Never gonna give you up”. 社交媒体们纷纷推波助澜认为该病是由于磁共振成像引起，这种说法完全没有事实依据，还引起了人们对3T和7T磁共振使用的担忧。RAGS最近发起了一个题为“永远不会放弃你”的活动，成功消除了人们对MRI和RIP之间有关联的认识。 该病非常典型，见一次就将过目不忘！你学会了吗？ |
