Triple discrete fungus balls of the paranasal sinuses

Area of Science:

• Otolaryngology
• Medical Mycology
• Radiology

Background:

• Paranasal sinus fungus balls (PSFB) are typically found in a single sinus, most commonly the maxillary sinus.
• Multisinus involvement is infrequent (6%), and when present, sinuses are usually contiguous.
• Bilateral PSFB are exceptionally rare in medical literature.

Observation:

• This case presents a unique instance of PSFB affecting three distinct, non-contiguous paranasal sinuses simultaneously.
• The patient exhibited discrete fungal masses in separate sinus cavities, a presentation not previously documented.

Findings:

• The study documents the first reported case of triple discrete paranasal sinus fungus balls.
• This finding challenges the established understanding of PSFB localization patterns.

Implications:

• This case highlights the potential for unusual presentations of PSFB, necessitating broader diagnostic considerations.
• It underscores the importance of comprehensive imaging in diagnosing complex or atypical paranasal sinus conditions.
