Insights
Pediatric brain tumors can present with seizures, delaying diagnosis. Prompt treatment, including surgery and chemotherapy, can significantly reduce or eliminate seizures in children.
Area of Science:
- Pediatric Neurology
- Pediatric Oncology
- Neuro-oncology
Background:
- Seizures are a common presenting symptom in children with primary brain tumors.
- Early diagnosis and treatment of pediatric brain tumors are crucial for patient outcomes.
Purpose of the Study:
- To investigate the role of seizures as the initial clinical manifestation of primary brain tumors in children.
- To analyze the diagnostic delay, treatment strategies, and seizure control following intervention for pediatric brain tumors presenting with seizures.
Main Methods:
- Retrospective analysis of 81 children with primary brain tumors treated at a tertiary pediatric oncology unit over 5 years.
- Detailed review of clinical presentation, seizure characteristics, electroencephalogram (EEG) findings, tumor histology, treatment modalities, and outcomes.
Main Results:
- Seizures were the presenting symptom in 10 (12%) of the children.
- Partial seizures were most common, with focal/lateralizing EEG abnormalities in most cases.
- Astrocytoma was the predominant histology, and diagnostic delay ranged from 2 weeks to 2 years (mean 6 months).
- Post-treatment, 3 patients became seizure-free, and 5 experienced significant seizure reduction (50-80%).
Conclusions:
- Seizures can be a significant indicator of primary brain tumors in children, often leading to diagnostic delays.
- Multimodal treatment, including surgical resection and adjuvant therapies, can effectively manage seizures in this population.
- Effective seizure control post-treatment suggests a favorable prognosis for some pediatric brain tumor patients presenting with epilepsy.
Abstract:
Seizures were the presenting clinical symptom in 10 (12%) of 81 consecutive children with a primary brain tumour treated in a tertiary paediatric oncology unit over 5 years. Nine patients experienced partial seizures, and in seven a waking electroencephalogram showed focal or lateralising abnormalities. Astrocytoma was the most common tumour histology. The delay in tumour diagnosis from the onset of seizures ranged from 2 weeks to 2 years with a mean of 6 months. Complete resection of the tumour was the only treatment in three patients and four underwent resection followed by radiotherapy and/or chemotherapy. Two patients died. Three patients became seizure free receiving no antiepileptic medication and the remaining five showed a 50-80% reduction in seizures between 2 and almost 5 years following treatment.

Seizures: Classification
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:
