摘要

背景:在核医学文献中很少讨论黑骨化症。一名25岁的女性患者以1年的拇囊炎疼痛、硬化改变和左大脚趾指间关节皮肤色素沉着史就诊。清创后创面出现溃疡、愈合不良及角化过度。左脚平片偶见骨质疏松。材料与方法:x线片显示大脚趾皮质性骨质增生。经过进一步的x线评估和左脚骨扫描,放射学发现仍然显示骨质疏松症。进一步的Tc-99m MDP骨扫描显示骨盆左侧和整个左下肢广泛受累。全身骨平片扫描及MRI也显示骨质疏松。结果:左大脚趾临床表现为指间关节形成痂、清创、溃疡、角化过度。x光片常显示骨增厚,类似滴落的蜡烛蜡,骨膜皮质增厚,局限于硬膜;可以很明显地看到它从关节流向下一块骨头。在核医学图像中,放射性示踪剂摄取的增加通常出现在晚期骨扫描中。结论:在骨盆、左股骨、小腿和左脚MRI的后续x线片中,这些病变的显像和x线片分布具有很好的相关性。本研究报告了一例罕见的影响大脚趾的骨质疏松症,并回顾了这种罕见骨的各种影像学诊断的作用

Demonstration of melorheostosis on bone scan
Background: Melorheostosis has been discussed infrequently in the nuclear medicine literature. A 25-year-old female patient presented with a one-year history of bunion pain, sclerotic change and skin pigmentation on the left big toe interphalangeal joint. Ulceration, poor healing and hyperkeratoses of the wound were noted post debridement. The plain film of the left foot incidentally showed melorheostosis. Materials and Methods: Radiographs revealed cortical hyperostosis of big toe. After further evaluation by X-ray and bone scan of the left foot, the radiologic findings still indicated melorheostosis. A further Tc-99m MDP bone scan revealed extensive bone involvement in the left side of the pelvis and entire left lower extremity. Moreover, plain film whole body bone scan and MRI also revealed melorheostosis. Results: The clinical symptoms of her left big toe included interphalangeal joint callus formation, debridement, ulcer and hyperkeratoses. X-rays often reveal a pattern of thickened bone that resembles dripping candle wax, with periosteal cortical thickening, confined to sclerotomes; and can be seen apparently flowing across joints to the next bone. In the nuclear medicine image, an increase in radiotracer uptake is usually present on late phase bone scans. Conclusion: There was excellent correlation between the scintigraphic and radiographic distribution of these lesions in the following radiographs of pelvis, left femur, lower leg and MRI of the left foot. This study reported a rare case of melorheostosis affecting the big toe and reviewed the role of various imaging diagnosis of this rare bone
