Summary
This study details a rare epithelial cyst in the brain causing neurological symptoms. Surgical intervention was initially successful, but cyst regrowth necessitated a shunt, highlighting management challenges for these rare intracranial lesions.
Area of Science:
- Neurosurgery
- Neuropathology
- Radiology
Background:
- Epithelial cysts are rare intracranial lesions.
- Accurate diagnosis and nomenclature of benign cystic lesions are crucial.
Observation:
- A 60-year-old woman presented with dysarthria and gait disturbance.
- Brain CT revealed a 6 cm right frontal convexity cyst causing midline shift.
- Initial surgical fenestration was followed by cyst regrowth after 5 years.
Findings:
- Microscopy revealed a cyst wall with a monolayer of flat epithelium and basement membrane.
- Electron microscopy showed epithelial cells with endoplasmic reticulum and mitochondria, lacking cytoplasmic membrane interdigitation.
- The term "epithelial cyst" may be ambiguous, prompting discussion on nomenclature.
Implications:
- This case highlights the potential for recurrence and the need for long-term monitoring of intracranial epithelial cysts.
- Further discussion on the pathogenesis and precise classification of such benign cystic lesions is warranted.
- Optimal surgical and management strategies for recurrent intracranial cysts require careful consideration.
