Extra- and intraneural ganglion cysts have been described in the literature. The tibial nerve ganglion is uncommon and its occurrence without intra-articular extension is atypical. The pathogenesis of cystic degeneration localized to connective and perineural tissue secondary to chronic mechanical irritation or idiopathic mucoid degeneration is hypothesized. Since the above pathology is extremely rare and the magnetic resonance imaging examination detects the defining characteristics of the intrinsic alterations of the tibial nerve, the authors illustrate such a case of tibial intaneural ganglion cyst with its magnetic resonance neurography and sonography appearances.
文献中已描述了神经外和神经内腱鞘囊肿。胫神经腱鞘囊肿并不常见，其无关节内延伸的情况并不典型。据推测，囊肿变性的发病机制是由于慢性机械刺激或特发性黏液样变性继发于结缔组织和神经周围组织。由于上述病理情况极为罕见，且磁共振成像检查可检测出胫神经内在改变的特征性表现，作者通过磁共振神经造影和超声检查结果展示了这样一例胫神经内腱鞘囊肿病例。
