Abstract
INTRODUCTION: The patient had an enlarging left-side neck mass without neurological symptoms. METHODS: Magnetic resonance (MR) imaging revealed a well-demarcated mass close to the left root of C4. RESULTS: During the surgery, we confirmed a tumour arising from the cervical phrenic nerve. Although neurogenic tumours of the phrenic nerve are associated with a high risk of causing hemidiaphragm palsy after the total excision, we could carry out a total excision without deficit. CONCLUSION: The pathological examination revealed a neurofibroma.
