Summary
This report details a rare case of a non-traumatic intradiploic arachnoid cyst, a slow-growing swelling in the skull, diagnosed during surgery. The study highlights this unusual extradural intracranial condition and its key characteristics.
Area of Science:
- Neurosurgery
- Neuropathology
Background:
- Intradiploic arachnoid cysts are rare, extradural intracranial lesions.
- Non-traumatic etiology is exceptionally uncommon, posing diagnostic challenges.
Observation:
- A 65-year-old woman presented with a slow-growing right frontotemporal swelling.
- No history of head trauma was reported.
- Diagnosis was confirmed intra-operatively.
Findings:
- The case represents a rare instance of a non-traumatic intradiploic arachnoid cyst.
- This extradural lesion occurred without preceding trauma.
- Characteristic features of such cysts are reviewed.
Implications:
- Highlights the importance of considering rare diagnoses in the differential for cranial swellings.
- Contributes to the limited literature on non-traumatic intradiploic arachnoid cysts.
- Aids in understanding the clinical presentation and diagnostic features of this entity.
