Case ReportsIntractable hiccups: a rare presentation of phrenic nerve schwannoma.
Schwannoma rarely involves the phrenic nerve. We report a unique case of schwannoma as a cause of chronic hiccups due to the involvement of phrenic nerve. ⋯ Postoperatively, the patient showed marked improvement in his symptoms and the hiccups were almost completely resolved. Although they are very rare, schwannomas of the phrenic nerve should be considered in the differential diagnosis of chronic hiccups.
