Abstract :Backround: Hydatid cyst, is caused by infestation with egg of Echinococcus granulosus/E.multilocularis, a ~2–7 mm long tapeworm found in dogs (definitive host), sheeps, cattles and pigs (intermediate host). Schwannomas are generally known as benign neurogenic tumors that arise from many different organs in the body, but rarely from the gastrointestinal tract. In this study, a case of hydatid cyst accompanied by a surgey of sacro-lumbar schwannoma is presented. Case presentation: A 36-year-old female patient, who applied to the neurosurgery clinic with a complaint of right-sided sciatica and lumbar pain was operated for shwannoma. During the same operation, a neoplasmic structure extending from the subcutaneous area of the lower right side of the sacrum region to the paravertebral muscle was removed. As a result of pathological examination, this structure was reported to be the cuticular and scolex structure of the hydatid cyst. After the operation, the patient was referred to the infectious diseases clinic. Anti-helmintic treatment was started and the patient was discharged in recovery. Conclusions: When a rare area is involved, hydatid cyst disease must be diagnosed using a combination of serological tests and imaging methods. As in this case; In case of unusual presentations or atypical findings on imaging studies, the cyst should be evaluated for hydatid disease and studies should be performed to confirm the diagnosis.
