Summary
Cystic meningiomas are rare brain tumors, especially in children. Characteristic CT scan findings, including cystic components and dural attachment, aid in their preoperative diagnosis.
Area of Science:
- Neurosurgery
- Neuroradiology
- Pediatric Oncology
Background:
- Cystic meningiomas represent a rare subtype of meningioma, accounting for approximately 10% of pediatric cases.
- The literature contains limited case reports, with only 61 instances of cystic meningiomas documented.
- This study contributes additional case data to the existing body of knowledge on this uncommon tumor.
Purpose of the Study:
- To describe the typical computed tomography (CT) findings associated with cystic meningiomas.
- To discuss the differentiating features of cystic meningiomas from other cystic mass lesions.
- To improve the preoperative diagnostic accuracy of cystic meningiomas, particularly in pediatric patients.
Main Methods:
- Retrospective analysis of 6 cases of cystic meningioma.
- Review of existing literature on cystic meningioma cases.
- Correlation of CT imaging findings with histopathological diagnoses.
- Comparison of CT features with other cystic intracranial masses.
Main Results:
- Cystic meningiomas often present with a cystic component on CT scans.
- Key CT findings include smooth outlining, marked enhancement, and dural attachment.
- These features, when present, suggest a preoperative diagnosis of cystic meningioma.
Conclusions:
- A cystic component, smooth margins, significant enhancement, and dural attachment on CT are indicative of cystic meningioma.
- The diagnostic suspicion for cystic meningioma should be heightened in pediatric cases exhibiting these CT characteristics.
- Accurate preoperative diagnosis can guide surgical planning and patient management.
