Dysplasia epiphysealis hemimelica is a rare osteocartilaginous overgrowth syndrome of bone epiphysis, mostly encountered in the lower limbs of immature skeleton patients. We report a case of proximal humerus presentation in an adult male, with neither articular involvement nor clinical dysfunction. This case highlights the importance of stratification into intra- and extra-articular lesions, as this distinction ultimately influences both symptoms and treatment outcome. In addition, the case highlights the importance of specific imaging modalities, such as CT and MR images, which provide excellent anatomic location of the lesion, adequate extension of cartilaginous components, exact status of articular cartilage, and accurate assessment of neighboring structures, such as vessels, nerves, ligaments, tendons, and muscles. The imaging features are described, the relevant literature is reviewed, and salient features are discussed.
半侧肢体骨骺发育异常是一种罕见的骨骺骨软骨过度生长综合征，多见于未成熟骨骼患者的下肢。我们报告一例成年男性近端肱骨受累的病例，该病例既无关节受累也无临床功能障碍。该病例突出了区分关节内和关节外病变的重要性，因为这种区分最终会影响症状和治疗结果。此外，该病例还突出了特定成像方式（如CT和MR图像）的重要性，这些成像方式能提供病变的精确解剖位置、软骨成分的充分延伸、关节软骨的准确状态，以及对血管、神经、韧带、肌腱和肌肉等邻近结构的准确评估。本文描述了影像学特征，回顾了相关文献，并讨论了显著特征。
