“…They most often affect the fibular (peroneal) nerve, arising there from the superior tibiofibular joint, but examples have been reported to involve the ulnar nerve at the elbow (Zum Busch, 1895;Jardini, 1907;Tanaka et al, 1969;Hori et al, 1986;Allieu et al, 1987;Hansis et al, 1988;Allieu and Cenac, 1989;Ferlic and Ries, 1990;Inhofe and Moneim, 1996;Harway, 1997;Uetani et al, 1998;Choi et al, 1999;Sharma et al, 2000;Chick et al, 2001;Chan et al, 2003;Rezzouk and Durandeau, 2004;Boursinos and Dimitriou, 2007;Lohmeyer et al, 2007). These latter cases in every way resemble the case reported herein.…”

We describe the first reported case of an intraneural ganglion cyst, an ulnar (''cubital'') intraneural cyst, which, on literature review, dated to 1810. For over 80 years, its original brief description by Beauchêne was wrongly attributed to Duchenne, effectively making the reference and specimen inaccessible to scrutiny. Fortunately, the intact cyst had been safely housed in the Musée Dupuytren, Paris, France, thus permitting its examination. Although originally described as a ''serous'' cyst, our present understanding of the anatomy of the ulnar nerve and of peripheral nerve pathology allowed us to reinterpret it as a mucin-filled, elbow-level, ulnar intraneural ganglion cyst. In addition to its description as a fusiform cystic enlargement of the nerve, we documented similar enlargement of a lumen-bearing branch, the articular branch at the level of the elbow. Based on our assessment of the specimen and with a modern perspective, we concluded that the origin of the cyst was from the posteromedial aspect of the elbow joint and that its fluid content, having dissected through a capsular defect, followed the path of the articular branch into the parent ulnar nerve. The purpose of this report is to clarify historical misconceptions regarding the pathogenesis of this controversial entity. Clin. Anat. 21:611-618, 2008. V V C 2008 Wiley-Liss, Inc.

“…Nerve sheath ganglions occurring within the sheaths of the peripheral nerves have been reported in the literature as early as 1963, but they are relatively rare findings [2]. In the upper extremity, nerve sheath ganglions occur most commonly in the ulnar nerve, as it curves through the cubital tunnel [5,6,12,18]. Other reports in the median nerve, supraspinatus nerve and the posterior interosseous nerve were also noted [6].…”

Nerve sheath ganglion is a relatively rare clinical entity commonly found in the peroneal nerve in the lower limb or the ulnar nerve in the upper extremity. It is rarely found in the tibial nerve. The occurrence of a nerve sheath ganglion in a patient's tibial nerve has been identified. The initial presentation of the tumor mass has been very similar to that of a Baker's cyst, namely a soft undulating popliteal mass. Yet, the case also presented symptoms and signs of tibial nerve compressive neuropathy. We present here a rare case of nerve sheath ganglion of the tibial nerve. Clinical courses of the patient were reviewed, and relevant issues were discussed with a thorough literature review.

“…Nerve sheath ganglions are most commonly found in peroneal or tibial nerve in the lower limb [12,40] or ulnar nerve in the upper extremity [9,11]. This type of intramuscular ganglion is called an intramuscular cyst arising from the neurilemma.…”

“…However, intramuscular cysts at the proximal calf are rare, and the etiologies of these cysts are diverse. Some case reports have shown that atypical Baker's cysts [3,4], cysts arising from the proximal tibiofibular joint (PTFJ) [5][6][7][8] and nerve sheath ganglions [9][10][11][12], can lead to intramuscular cysts at the proximal calf. The clinical presentation of these cysts is usually a painless mass along the calf.…”

Intramuscular Cysts at the Proximal Calf: Two Case Reports and a Systematic Review of Literature

Intramuscular cysts at the proximal calf are rare; however, their etiology is diverse, making accurate diagnosis and treatment difficult. To our knowledge, there are no previous publications in literature about intramuscular cysts at the proximal calf, arising from different origins. This article describes two rare cases with intramuscular cysts. Case 1 was diagnosed as an intramuscular ganglion cyst arising from the proximal gastrocnemius medialis muscle, and arthroscopic examination as well as open cyst excision was performed. Case 2 was another type, which has never been reported in the literature. It was diagnosed as diffuse pigmented villonodular synovitis (PVNS), with the intramuscular cyst arising from PVNS, and only arthroscopic synovectomy was performed. The diagnoses for these cases were confirmed by histopathology. In addition, we have summarized intramuscular cysts at the proximal calf by a systematic literature review and divided them into five types based on their origin. The five types are, intramuscular cysts arising from the muscular tissue, knee joint, proximal tibiofibular joint, the neurilemma and PVNS. The treatment of intramuscular cysts varies based on their origin; hence, it is important to identify the origin.
