Abstract:
The authors report a case of a 6 month-old male presenting with increasing head circumference and a large benign intraventricular meningioma which was grossly removed at the initial surgery. Twenty-four months later, the patient returned with subcutaneous and osseous metastatic lesions at the site of the previous craniotomy, revealing the same histology as the original tumour. The presentation, pathology and management of this unique case are discussed.
Insights
A benign intraventricular meningioma in a 6-month-old recurred as metastatic lesions after 24 months. This rare case highlights the potential for late-stage recurrence and metastasis in pediatric meningiomas.
Area of Science:
- Neuro-oncology
- Pediatric Neurosurgery
- Tumor Biology
Background:
- Intraventricular meningiomas are rare brain tumors, particularly in infants.
- Benign meningiomas are generally associated with a good prognosis after complete resection.
Observation:
- A 6-month-old male presented with an increasing head circumference due to a large intraventricular meningioma.
- The tumor was grossly removed during initial surgery.
Findings:
- Twenty-four months post-surgery, the patient developed subcutaneous and osseous metastatic lesions at the prior craniotomy site.
- Histological analysis confirmed the metastatic lesions were identical to the original benign meningioma.
Implications:
- This case underscores the importance of long-term surveillance for pediatric intraventricular meningiomas, even those initially classified as benign.
- It suggests that certain benign meningiomas may possess metastatic potential, necessitating further research into their biological behavior.
- Management strategies may need to consider the possibility of late recurrence and metastasis in this population.
