Endoscopic Endonasal Trans-sphenoidal Approach: Minimally Invasive Surgery for Pituitary Adenomas
Published on: January 17, 2018
Invasive aspergillosis of the sphenoid sinus manifested as a pituitary tumor
Abstract:
Aspergillus infection of the paranasal sinuses is rare but is the most common fungal infection of these structures and should be suspected when sinusitis does not respond to antibacterial drugs. Our case involved the sphenoid sinus, and was initially thought to be a nonfunctioning pituitary tumor. Treatment of Aspergillus sinusitis principally involves surgical debridement, reestablishment of aeration and drainage of the involved sinuses, and adjunctive antifungal chemotherapy.
Insights
Aspergillus sinusitis, a rare fungal infection, is the most common cause of fungal sinusitis. It requires surgical debridement and antifungal treatment when standard antibiotics fail.
Area of Science:
- Mycology
- Otolaryngology
- Infectious Diseases
Background:
- Aspergillus infection of paranasal sinuses is uncommon but represents the most frequent fungal sinusitis.
- It should be considered in cases of sinusitis unresponsive to antibacterial therapy.
Observation:
- A case presented with sphenoid sinus involvement, initially misdiagnosed as a nonfunctioning pituitary tumor.
- This highlights the diagnostic challenges of fungal sinusitis.
Findings:
- Treatment primarily involves surgical intervention for debridement and restoring sinus aeration and drainage.
- Adjunctive antifungal chemotherapy is a crucial component of management.
Implications:
- Early suspicion and diagnosis of Aspergillus sinusitis are vital for effective treatment.
- Multidisciplinary approaches combining surgery and antifungal agents improve patient outcomes.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
