Background:
Fungal infection is a rare pathology in the sphenoid sinus, and extension into the pituitary fossa with visual loss has only been described in a few reports in the literature. Following publication of a recent report of pituitary abscess by Candida glabrata, we describe our own experience with a similar pathology.
Case Description:
In the present report, we overview a diabetic patient who sustained aspergilloma in his sphenoid sinus with extension to the pituitary fossa. Clinical presentations are discussed along with an emphasis on the role of endoscopic endonasal drainage of the abscess as the mainstay of treatment. Following administration of intravenous amphotericin B for 6 days, endoscopic drainage of the aspergillus abscess was done. Visual acuity improved immediately after the operation. At the 12-month follow-up visit, the improvement in visual acuity was maintained and magnetic resonance imaging showed no recurrence.
Conclusion:
Correction of the underlying immune deficiencies, administration of intravenous antifungal agents perioperatively, endoscopic endonasal drainage of abscess, and a meticulous debridement of necrotic material, followed by a course of oral antifungal medication, comprises the standard treatment protocol for a fungus ball (aspergilloma) of the sphenoid sinus.
Insights
Fungal infection of the sphenoid sinus can extend to the pituitary fossa, causing vision loss. Endoscopic drainage and antifungal treatment are effective for aspergilloma, restoring visual acuity.
Area of Science:
- Otolaryngology
- Neurosurgery
- Infectious Diseases
Background:
- Fungal infections of the sphenoid sinus are rare, with pituitary fossa extension and visual loss being exceptionally uncommon.
- Previous reports highlight pituitary abscesses caused by fungi; this case details an aspergilloma with similar invasive characteristics.
Observation:
- A diabetic patient presented with an aspergilloma in the sphenoid sinus that had extended into the pituitary fossa.
- The patient experienced visual loss secondary to the fungal invasion of the pituitary region.
Findings:
- Endoscopic endonasal drainage of the sphenoid sinus aspergillus abscess was performed after a 6-day course of intravenous amphotericin B.
- Immediate improvement in visual acuity was observed post-operatively, with sustained recovery at 12-month follow-up and no recurrence on MRI.
Implications:
- This case underscores the importance of prompt diagnosis and multidisciplinary management for fungal sphenoid sinus infections with pituitary extension.
- A comprehensive treatment protocol involving antifungal therapy, surgical drainage, and addressing immune deficiencies is crucial for favorable outcomes.
