Abstract

Hydatid disease (also known as hydatidosis) is a cyclozoonotic infection caused by the cestode genus Echinococcus. The incidence of humans infected with hydatid disease is approximately 1.0-2.0:1,000, although it may be higher in rural areas of regions that are affected. Infection occurs via ingestion of infected meat, A hydatid cyst of the head and neck is a very rare condition, even in areas where Echinococcus infestation is endemic. Primary infection of the Lt sphenoid sinus is odd and very rare.

Case report: We report a rare case of primary hydatid cyst of the Lt sphenoid sinus in a 65-year-old Sudanese Female. The initial diagnosis of the presence of a cystic mass was the result of physical examination, computed tomography (CT) scan,MRI(magnetic resonance imaging) and Histopathology, We diagnose the cystic mass by biopsy using FESS(Functional Endoscopic Sinus Surgery), A definitive diagnosis was confirmed by postoperative histopathologic examination. Conclusion: Hydatid cyst of the sphenoid sinus is a highly rare presentation, However, this condition should be considered in differential diagnosis of cystic lesions of the sinuses. This article reviews a case report involving this rare condition.

Keywords: Cystic lesion; Echinococcus; Hydatid cyst; sphenoid sinus.
