Primary hydatid cyst of the maxillary sinus

Area of Science:

• Otorhinolaryngology
• Parasitology
• Ophthalmology

Background:

• Hydatid cysts are typically found in the liver and lungs.
• Maxillary sinus involvement by hydatid disease is exceptionally rare.
• Orbital compression by sinonasal masses can lead to significant visual impairment.

Observation:

• A case of a hydatid cyst originating in the maxillary sinus is described.
• The cyst presented with mass effect, causing direct compression of the adjacent orbit.
• This presentation is unique and has not been reported previously in the literature.

Findings:

• The study details an unprecedented instance of a hydatid cyst within the maxillary sinus.
• The cyst's anatomical location led to direct pressure on orbital structures.
• Diagnostic imaging confirmed the cyst's origin and its impact on the orbit.

Implications:

• This case expands the known spectrum of hydatid cyst locations.
• It underscores the importance of considering parasitic infections in sinonasal and orbital pathologies.
• Further research may be needed to understand the pathogenesis of such rare presentations.
