A 48-year-old man presented with pain in the right wrist. A roentgenogram showed symmetrically located, well-demarcated lucencies in both scaphoids. These lesions showed homogeneous intermediate signal intensity on T1-weighted MR images and homogeneous high signal intensity on T2*-weighted MR images. Histopathological analysis revealed the lesion in the right hand as an intraosseous ganglion. The reason why the lesions were located on the palmar side is discussed.
一名48岁男性因右腕疼痛就诊。X线片显示双侧舟状骨有对称分布、边界清晰的透亮区。这些病变在T1加权磁共振成像上呈均匀中等信号强度，在T2*加权磁共振成像上呈均匀高信号强度。组织病理学分析显示右手病变为骨内腱鞘囊肿。本文讨论了病变位于掌侧的原因。
