We report a case of a 45 year's old woman with a radial nerve entrapment caused by a desmoid tumor involving the right forearm. This case is outstanding because of the posterior interosseous nerve is entrapped inside the tumor. The marginal excision of the mass while preserving the intratumoral radial nerve was laborious. The radial nerve entrapment caused by a desmoid tumor is very rare and intratumoral radial nerve entrapment is also exceptional. The surgical treatment was challenging and the prognosis is uncertain because of the high rates of recurrence of the desmoid tumor.
