To clarify the clinicopathological features of periosteal ganglion.
Three patients with periosteal ganglion were studied clinicopathologically.
One patient was selected from the files of our institute and two from a consultation file.
All three lesions were located over the medial aspect of the tibia. Plain radiographs showed cortical erosions of varying degrees and mild periosteal reaction of the medial side of the tibia. MR images demonstrated well-circumscribed lesions overlying the cortical bone of the tibia, shown as low-intensity areas on T1-weighted images. On T2-weighted images, lesions were homogeneous, lobulated, and showed a characteristic markedly increased signal intensity. These findings are helpful in making a diagnosis of periosteal ganglion. Each patient had an uneventful clinical course after an excision involving the wall of the ganglion, the adjoining periosteum, and the underlying sclerotic cortical bone.
阐明骨膜囊肿的临床病理特征。
对3例骨膜囊肿患者进行临床病理研究。
1例患者选自本院病例档案，2例选自会诊档案。
所有3个病变均位于胫骨内侧。X线平片显示不同程度的皮质侵蚀及胫骨内侧轻度骨膜反应。磁共振成像（MR）显示胫骨皮质骨上方边界清晰的病变，在T1加权像上呈低信号区。在T2加权像上，病变均匀、分叶状，信号强度明显增高，具有特征性。这些表现有助于骨膜囊肿的诊断。每位患者在切除囊肿壁、相邻骨膜及下方硬化皮质骨后临床过程顺利。
