Summary
A simple bone cyst, an uncommon skull base pathology, can cause complex partial seizures. Endoscopic surgery offers a less invasive treatment option for these rare brain lesions.
Area of Science:
- Neurosurgery
- Skull Base Surgery
- Neuroradiology
Background:
- Intra-axial brain lesions typically present with seizures.
- Simple bone cysts are rare bony pathologies.
- Skull base lesions can manifest with neurological symptoms.
Observation:
- A 20-year-old male presented with complex partial seizures.
- MRI revealed a cystic lesion in the middle cranial fossa.
- CT demonstrated a cystic lesion involving the sphenoid bone with CSF outpouching.
Findings:
- The lesion was histopathologically confirmed as a simple bone cyst.
- Endoscopic transmaxillary transpterygoid approach was utilized for excision.
- This approach was chosen for its reduced post-operative morbidity compared to transcranial methods.
Implications:
- Highlights the unusual presentation of simple bone cysts.
- Demonstrates the efficacy of endoscopic skull base surgery.
- Suggests neuro-endoscopy as a preferred method for managing such lesions.
