Abstract
Primaryintramuscularhydatiddiseaseoftheparaspinalmusclesisexceptionallyrare, particularlyintheabsenceofhepaticorpulmonaryinvolvement.Itsnonspecificclinical andradiological featuresoftenmimicsoft tissuetumors, creatingdiagnosticchallenges for neurosurgeons practicing in endemic regions. A 22-year-oldwoman presentedwithaslowlyenlarging,mildlypainfulrightlumbarparaspinalmasswithout animal exposureor systemic symptoms.Magnetic resonance imaging revealeda multiloculatedcystic lesionextending fromL2toL4that lackeddefinitivehydatid featuresandcouldnotbeclearlydistinguishedfromasynovial cyst, cysticschwannoma,abscess,orepidermoidcyst.SerologyshowedpositiveEchinococcusgranulosus IgG(ELISA).Thepatientunderwentposteriorenblocexcision.Intraoperativemanagement includedmeticulouscontainmentandirrigationwith3%hypertonicsalineand povidone-iodineforapproximately10minutes, followedbycopioussalinewashout.
