The bursa of the tibial collateral ligament (TCL) may be visualized at magnetic resonance (MR) imaging when it becomes distended with fluid. In the authors' experience, this finding signifies a pathologic condition either in the medial capsuloligamentous complex or in the bursa itself. Such a finding may indicate TCL bursitis. TCL bursitis can be suspected in the setting of isolated pain in the medial joint line in the absence of mechanical symptoms. Prolonged relief of symptoms after injection of steroid into the bursa is supportive of the diagnosis. Seven cases are presented in which a fluid-filled TCL bursa was identified at MR imaging. In five cases, TCL bursitis was suspected. The differential diagnosis for the MR findings is discussed.
当胫侧副韧带（TCL）的滑囊因液体充盈而扩张时，可在磁共振（MR）成像中显示出来。根据作者的经验，这一发现表明内侧关节囊韧带复合体或滑囊本身存在病理状况。这样的发现可能提示TCL滑囊炎。在没有机械性症状的情况下，若内侧关节线处出现孤立性疼痛，可怀疑TCL滑囊炎。向滑囊内注射类固醇后症状长期缓解有助于诊断。本文报告了7例在MR成像中发现液体充盈的TCL滑囊的病例。其中5例怀疑有TCL滑囊炎。文中还讨论了这些MR表现的鉴别诊断。
