Peripheral Nerve Examination

The ulnar nerve fibres originate predominantly from the C8–T1 nerve roots and begin as a terminal branch of the medial cord. As it travels through the upper arm, it passes under a band of deep brachial fascia that has been deemed the arcade of Struthers. The nerve then moves between the medial epicondyle and the olecranon in a highly vulnerable position. The cubital tunnel retinaculum overlies the nerve and passes between the olecranon and the medial epicondyle [2]. This structure is also known as Osborne's band [3] (Figure 8C.1).

Gantzer’s muscle is associated with flexor pollicis longus, flexor digitorum profundus, and flexor digitorum superficialis. It is generally described as an accessory head of flexor pollicis longus. It can arise from the medial epicondyle, the coronoid process, from both of these structures, or from flexor digitorum superficialis (Macalister 1875; Knott 1883a; Mori 1964; Bergman et al. 1988; Akita and Nimura 2016b). Zdilla et al. (2019) reported an origin from the brachialis fascia. It inserts onto the tendons or muscle bellies of flexor pollicis longus and/or flexor digitorum profundus (Macalister 1875; Knott 1883a; Mori 1964; Bergman et al. 1988; Caetano et al. 2015; Akita and Nimura 2016b).

Superficial venous systemThe dorsum of the hand displays the dorsal venous network which drain into the cephalic and basilic veins on the lateral and medial side, respectively.The cephalic vein ascends on the lateral side of the forearm and arm and it passes through the deltopectoral groove in the shoulder before emptying into the axillary vein.The basilic vein runs posteromedially to pass anterior to the medial epicondyle of the humerus. In the arm, it pierces the brachial fascia and joins the paired deep brachial veins to form the axillary vein.The median cubital vein connects the cephalic and basilic veins anterior to the cubital fossa.

The radiological differential diagnosis of CSD includes other infections and a range of benign and malignant soft tissue tumors, such as peripheral nerve sheath tumors, synovial sarcoma, leiomyosarcoma, and distant nodal metastasis (Mazur-Melewska et al. 2015, Bernard et al. 2016, Chen et al. 2018). As seen in our study, the radiologist’s experience and knowledge of different imaging features may play an important role in diagnosing typical and atypical findings in the spectrum of CSD, resulting in a significantly lower number of equivocal findings suspicious of malignancy. In addition, for the differentiation of lymph nodes in the epitrochlear region from other soft tissue masses, key anatomical features, including location posterior to the basilic vein, superficial to the brachialis muscle and brachial fascia or intermuscular septum covering the medial head of the triceps and ulnar nerve, can be used (Bernard et al. 2016).
