Insights
Headache in pediatric pseudotumor cerebri syndrome (PTCS) often involves the head, neck, and shoulders, and can be episodic or constant. Some children with PTCS experience no headache.
Area of Science:
- Pediatric Neurology
- Ophthalmology
- Neuroscience
Background:
- Headache is a common symptom attributed to increased intracranial pressure.
- Systematic studies on headache characteristics in pediatric pseudotumor cerebri syndrome (PTCS) are limited, especially with revised diagnostic criteria.
- Understanding these characteristics is crucial for accurate diagnosis and management.
Purpose of the Study:
- To systematically investigate headache characteristics in children diagnosed with or suspected of having PTCS.
- To compare headache patterns and locations between children with definite/probable PTCS and those with elevated or normal intracranial pressure without papilledema.
Main Methods:
- Retrospective cohort study of 127 pediatric patients treated for suspected or confirmed PTCS.
- Chart review to assess PTCS diagnostic criteria, headache characteristics, and associated symptoms.
- Chi-squared or Fisher's exact tests to compare headache frequencies between groups.
Main Results:
- Headache involving the head, neck, or shoulders was more frequent in definite PTCS patients compared to controls (OR=7.2 and 4.5, respectively).
- Headache patterns varied, with episodic headaches in 49% of definite PTCS cases.
- Eleven children (8.7%) reported no headache, including some with definite or probable PTCS.
Conclusions:
- Headache in pediatric PTCS frequently involves the head, neck, and shoulders.
- Headache presentation in PTCS can be episodic or constant, and is occasionally absent.
- Further research with larger cohorts is needed to confirm these findings.
Background:
Certain headache characteristics and associated symptoms are commonly attributed to increased intracranial pressure, but they have not been systematically studied among children in the context of revised diagnostic criteria for pseudotumor cerebri syndrome (PTCS).
Methods:
We performed a retrospective cohort study of patients treated for suspected or confirmed PTCS. Charts were reviewed for PTCS and headache diagnostic criteria and associated characteristics. Chi-squared or Fisher's exact tests were used to compare the frequency of headache characteristics between groups.
Results:
One hundred and twenty-seven individuals were identified: 61 had definite PTCS, 10 had probable PTCS, 31 had elevated opening pressure (OP) without papilledema, and 25 had normal OP without papilledema. Eleven children had no headache (6 with definite PTCS, 5 with probable PTCS). Headache pattern was episodic in 49% (95% CI: 34-64%) of those with definite PTCS, 18% (95% CI 6-37%) of those with elevated OP without papilledema, and 16% (5-36%) of those with normal OP without papilledema. Headache location was more likely to involve the head along with neck or shoulders in those with definite PTCS compared with elevated OP without papilledema (OR = 7.2, 95% CI: 1.9-27.6) and normal OP (OR = 4.5, 95% CI: 1.3-15.6) groups.
Discussion:
While missing data and small cohort size are limitations, this study suggests that headache in PTCS is more likely to involve the head along with neck/shoulders, and that headache in PTCS may be episodic or constant. Headache is occasionally absent in PTCS.
