Primary Hydatid Cyst of the Sphenoid Sinus: Case Report - 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.
