Endolymphatic sac papillary tumor (ELST) is an extremely rare and aggressive tumor characterized by hearing loss and temporal bone destruction.A case with clinical,imaging,pathologic and treatment data is reported and relevant literature is reviewed.A 25-year-old woman,with ELST underwent craniotomy for tumor subtotal resection,and the diagnosis was confirmed by pathologic examination.Postoperative radiotherapy consisted of 50.4 Gy/28 f was given accordingly.The patient is currently alive with no signs of tumor recurrence locally and no radiation side-effects observed after one year follow-up.Complete resection is impossible in most cases,local resection,adjuvant radiotherapy may provide favored local control.A long-term follow-up is highly advocated in consideration of its slow development course.
