A rare and unexpected clinical progress and location on a primary extradural spinal hydatid cyst in a pediatric patient: a case report.
BACKGROUND
Involvement of spine in patients with hydatid disease (HD) is less than 1% and primary intra-spinal extradural HD is extremely rare. Although this disease is introduced as benign pathology according to its clinical presentation and biological behavior, intraoperative rupture of the cyst may aggravate the patients' outcome in the long-term especially in pediatric patient population.


METHODS
We report a 9-year-old girl who presented a progressive neurological deterioration due to an enlargement of a ventrally located extradural hydatid cyst within the thoracic spinal canal. Total removal of the cyst was achieved by preserving the capsule integrity for preventing potential seeding. Our preoperative initial diagnosis based on the radiological findings was confirmed as cyst hydatid histopathologically.


CONCLUSIONS
Cyst hydatid should be considered in the differential diagnosis of the presence of homogenous cystic lesions with regular shape inside the spinal canal especially in patients from endemic region. To our knowledge, this pediatric patient is the first case of cyst hydatid located ventral side of the spinal cord extradurally located inside the spinal canal showing no extension.
