Sphenoethmoidal mucocele: radiographic diagnosis

Area of Science:

• Radiology
• Otolaryngology
• Neurosurgery

Background:

• Mucocele of the sphenoid sinus is a rare condition.
• Accurate diagnosis is essential for appropriate management.

Purpose of the Study:

• To review radiographic features of sphenoid sinus mucoceles.
• To assess differentiating radiographic findings for diagnosis.

Main Methods:

• Review of fourteen cases of sphenoid sinus mucocele.
• Detailed tomography in frontal, lateral, and submentovertex projections.

Main Results:

• Constant findings included sinus opacification and expansion/thinning of sinus walls.
• Contiguous ethmoid sinus opacification and pansinusitis were frequent.
• Absence of sellar enlargement distinguished mucoceles from intrasellar lesions.

Conclusions:

• Detailed tomography aids in recognizing sphenoid sinus mucoceles.
• Early diagnosis prevents visual loss and ensures proper surgical approach.
