The authors describe the case of an intraneural ganglion cyst involving a cranial nerve (V3), which was found to have a joint connection in support of an articular origin within the cranial nerves. An inferior alveolar intraneural cyst was incidentally discovered on a plain radiograph prior to edentulation. It was resected from within the mandibular canal with no joint connection perceived at surgery. Histologically, the cyst was confirmed to be an intraneural ganglion cyst. Reinterpretation of the preoperative CT scan showed the cyst arising from the temporomandibular joint. This case is consistent with the articular (synovial) theory of intraneural ganglion cysts. An anatomical explanation and potential joint connection are provided for this case as well as several other cases of intraneural cysts in the literature, and thus unifying cranial nerve involvement with accepted concepts of intraneural ganglion cyst formation and propagation.
作者描述了一例累及颅神经（V3）的神经内腱鞘囊肿病例，发现其存在关节连接，支持颅神经内的关节起源。在无牙颌之前的平片上偶然发现了一个下牙槽神经内囊肿。它从下颌管内切除，手术中未发现关节连接。组织学上，该囊肿被确认为神经内腱鞘囊肿。术前CT扫描的重新解读显示囊肿起源于颞下颌关节。该病例与神经内腱鞘囊肿的关节（滑膜）理论一致。本文为该病例以及文献中其他几例神经内囊肿病例提供了解剖学解释和潜在的关节连接，从而将颅神经受累与神经内腱鞘囊肿形成和传播的公认概念统一起来。
