Summary
Three unusual sphenoethmoidal mucoceles with intracranial extension were reported. Magnetic resonance imaging (MRI) is crucial for diagnosing these rare sphenoid sinus cysts and planning surgical treatment.
Area of Science:
- Neurosurgery
- Radiology
- Otolaryngology
Background:
- Sphenoethmoidal mucoceles are rare cystic lesions originating from the sphenoid and ethmoid sinuses.
- Intracranial extension of these mucoceles presents a significant diagnostic and surgical challenge.
Observation:
- Three cases of sphenoethmoidal mucoceles with intracranial extension are presented.
- Patients exhibited varied symptoms including visual disturbances, headache, nausea, and dizziness.
- Imaging studies, particularly magnetic resonance (MR) imaging, were vital in delineating the extent of the mucoceles.
Findings:
- One patient with a large middle fossa mucocele underwent successful frontotemporal craniotomy, leading to improved proptosis and cranial nerve function.
- Another patient with a sphenoid sinus mucocele had the lesion evacuated via a transnasal approach, resulting in an asymptomatic recovery.
- A third patient presented with a sphenoid sinus mucocele extending into the anterior cranial fossa, treated with sphenoidotomy, and experienced resolution of visual disturbances.
Implications:
- These cases highlight the importance of advanced imaging, especially MR imaging, for accurate diagnosis and preoperative assessment of sphenoethmoidal mucoceles.
- Surgical management varies depending on the mucocele's extent, with both open and endoscopic approaches demonstrating efficacy.
- Early diagnosis and appropriate surgical intervention are key to favorable outcomes in patients with intracranial extension of sphenoethmoidal mucoceles.
