Insights
This case report details a rare cystic meningioma in a child presenting with epilepsy and hemiparesis. Psammomatous meningioma, a rare subtype, highlights diagnostic challenges in pediatric neuro-oncology.
Area of Science:
- Neuro-oncology
- Pediatric Neurology
- Pathology
Background:
- Meningiomas are tumors arising from the meninges.
- Cystic meningiomas are a rare subtype, particularly in pediatric populations.
- Psammomatous meningiomas are characterized by psammoma bodies.
Observation:
- A 9-year-old girl presented with focal epilepsy and progressive hemiparesis.
- Brain CT revealed a calcified tumor with two attached cysts, showing strong contrast enhancement.
- Histological examination confirmed a psammomatous meningioma.
Findings:
- The psammomatous meningioma presented atypically with cystic components.
- The tumor's calcified nature and contrast enhancement were key radiological findings.
- Diagnosis of meningioma, especially rare subtypes, remains challenging, with a reported diagnostic rate of 38% in the literature.
Implications:
- This case underscores the importance of considering rare meningioma subtypes in pediatric patients with neurological symptoms.
- Advanced imaging techniques and histological analysis are crucial for accurate diagnosis.
- Understanding the pathogenesis and classification of meningiomas aids in clinical management and research.
Abstract:
A case of cystic meningioma in a 9-year old girl is reported. The initial clinical symptom was focal epilepsy, and this was followed by progressive hemiparesis. CT of the brain detected a calcified tumour to which two cysts were attached. The tumour was strongly enhanced by the contrast medium. Histology confirmed that the lesion was a meningioma of the psammous type. A review of the literature showed that this is a rare tumour the pathogenesis of which can be explained in various ways. Nautal's classification into 4 types is the most widely adopted. The diagnosis has been made in only 38% of the 166 cases published.
