Neck schwannoma with phrenic nerve involvement: A rare case report

Phrenic nerve schwannoma is an occasional axonal tumor that is mostly asymptomatic. In this report, a man with a painless lump in his neck was the subject. His diagnostic process included the recording of schwannoma. Phrenic schwannoma was removed by surgery without any complication during follow-up. Surgical excision under general anesthesia was done for the patient and during the surgical explore, the surgeon observed that, the schwannoma arose from the cervical phrenic nerve. The cervical mass was dissected from the phrenicnerve precisely by intracapsularenucleation technique. The phrenic involvements of schwannomas are extremely rare and mostly presented as a painless mass. Additionally, complete surgical excision of them is an efficient method.
