Summary
A rare case of sphenoid sinus agenesis was found in a 50-year-old woman. This anatomical variation was identified via CT scans before pituitary surgery, highlighting its importance in surgical planning.
Area of Science:
- Radiology
- Otolaryngology
- Anatomy
Background:
- Evaluation of sphenoid sinus aeration is crucial for endoscopic transsphenoidal hypophysectomy.
- Pituitary microadenoma necessitates surgical intervention, often via transsphenoidal approaches.
Observation:
- A 50-year-old woman presented for pre-surgical evaluation of sphenoid sinus aeration.
- Computed tomography (CT) scans revealed agenesis (absence) of the sphenoid sinuses.
- The right posterior ethmoidal cell was also found to be absent.
Findings:
- Sphenoid sinus agenesis is an uncommon finding documented by CT scans.
- This case is unique as it lacks associated craniofacial anomalies or skeletal diseases.
- Previous reports of sphenoid sinus agenesis are rare and often linked to specific conditions like Hand-Schuller-Christian disease.
Implications:
- Accurate anatomical assessment is vital for surgical safety and efficacy.
- Understanding rare anatomical variations like sphenoid sinus agenesis can prevent intraoperative complications.
- This case contributes to the limited literature on isolated sphenoid sinus agenesis.
