Sphenoidal mucoceles with intracranial extension
Journal of Computer Assisted Tomography
|June 1, 1979
Summary
Computed tomography effectively diagnosed two sphenoid sinus mucoceles extending into the brain. These lesions showed varied density but minimal contrast enhancement, aiding surgical planning.
Area of Science:
- Radiology
- Neurosurgery
- Otolaryngology
Background:
- Sphenoid sinus mucoceles are rare cystic expansions that can extend intracranially.
- Accurate preoperative diagnosis is crucial for effective surgical management.
Observation:
- Two cases of sphenoid sinus mucocele with intracranial extension were analyzed.
- Multiplanar computed tomography (CT) scans were utilized to delineate lesion extent.
Findings:
- One mucocele was isodense, while the other was hyperdense (98 Hounsfield units).
- Neither lesion showed significant enhancement after contrast administration.
Implications:
- CT imaging is vital for diagnosing and planning the surgical approach for intracranial sphenoid sinus mucoceles.
- Understanding the imaging characteristics, such as density and contrast enhancement, aids in preoperative assessment.
