Summary
Neurenteric cysts are rare developmental cysts. This case report details an unusual intracranial neurenteric cyst in a supratentorial convexity location, presenting with calcification, a previously unreported feature.
Area of Science:
- Neurology
- Developmental Biology
- Radiology
Background:
- Neurenteric cysts are uncommon developmental anomalies originating from endodermal epithelium.
- Intracranial neurenteric cysts are rare, typically occurring along the midline or in the posterior fossa.
Observation:
- A 68-year-old patient presented with seizures and was found to have an extra-axial lesion.
- Computed Tomography (CT) revealed a low-density lesion with wall calcification in the lateral supratentorial convexity.
Findings:
- Aspiration and biopsy confirmed the lesion as a neurenteric cyst.
- This represents an extremely rare location for such cysts, with calcification being a novel finding.
Implications:
- This case expands the known spectrum of neurenteric cyst presentations.
- The presence of calcification in supratentorial neurenteric cysts may influence diagnostic and treatment strategies.
