A rare cause of forearm pain: anterior branch of the medial antebrachial cutaneous nerve injury: a case report.

Yildiz N, Ardic F - J Brachial Plex Peripher Nerve Inj (2008)

Bottom Line: Pain and symptoms of dysestesia in the distribution of the right MACN were found.Electrophysiological examination confirmed the normality of the main nerve trunks of the right upper limb and demonstrated abnormalities of the right MACN when compared with the left side.Dysestesia and pain were relieved and no recurrence was observed after a follow-up of 14 months.

ABSTRACT

Introduction: Medial antebrachial cutaneous nerve (MACN) neuropathy is reported to be caused by iatrogenic reasons. Although the cases describing the posterior branch of MACN neuropathy are abundant, only one case caused by lipoma has been found to describe the anterior branch of MACN neuropathy in the literature. As for the reason for the forearm pain, we report the only case describing isolated anterior branch of MACN neuropathy which has developed due to repeated minor trauma.

Case presentation: We report a 37-year-old woman patient with pain in her medial forearm and elbow following the shaking of a rug. Pain and symptoms of dysestesia in the distribution of the right MACN were found. Electrophysiological examination confirmed the normality of the main nerve trunks of the right upper limb and demonstrated abnormalities of the right MACN when compared with the left side. Sensory action potential (SAP) amplitude on the right anterior branch of the MACN was detected to be lower in proportion to the left. In the light of these findings, NSAI drug and physical therapy was performed. Dysestesia and pain were relieved and no recurrence was observed after a follow-up of 14 months.

Conclusion: MACN neuropathy should be taken into account for the differential diagnosis of the patients with complaints of pain and dysestesia in medial forearm and anteromedial aspect of the elbow.

Figure 1: The view of dysesthesic region.

Mentions: There was a pain in her medial forearm and elbow. She felt abnormal when she was palpated on her medial forearm. During her examination, she was able to describe the point where her pain started in the proximal part of her elbow. On detailed neurological examination, a region of dysesthesia which extends from the elbow to the medial forearm was detected (Figure 1). The patient had no history of polyneuropathy, chronic systemic disease, injection or surgical intervention at the elbow. Range of motion, motor, and reflex examinations of both upper extremities were normal. Cervical spine examination was normal. Varus-valgus stress test for the elbow was normal. Medial epicondylitis test and tinel test for the ulnar nerve were negative.
