Insights
Neuroimaging is crucial for pediatric headaches in Saudi Arabia. Abnormal findings were common, especially in secondary headaches, highlighting the need for CT and MRI scans in diagnosis.
Area of Science:
- Pediatric Neurology
- Radiology
- Emergency Medicine
Background:
- Headaches are a common presenting complaint in pediatric emergency departments.
- Neuroimaging plays a vital role in diagnosing the underlying causes of headaches in children.
Purpose of the Study:
- To investigate neuroimaging findings in pediatric patients presenting with headaches in Saudi Arabia.
- To identify patterns and common abnormalities associated with primary and secondary headaches in children.
Main Methods:
- A retrospective cross-sectional study was conducted at King Abdullah Specialized Children Hospital (KASCH) from 2015 to 2020.
- Data from 263 pediatric patients with headache as the primary complaint were analyzed.
- Diagnoses were confirmed using computerized tomography (CT) scans and magnetic resonance imaging (MRI).
Main Results:
- Abnormal findings were observed in 50% of CT scans and 26% of MRI scans.
- Abnormalities were more prevalent in secondary headaches, with sinusitis, masses, and hydrocephalus being common CT findings.
- Masses, cysts, and hydrocephalus were the most frequent MRI findings in secondary headaches.
Conclusions:
- Neuroimaging (CT and MRI) is essential for diagnosing pediatric headaches, particularly secondary types.
- Sinusitis was a common association with headaches in children.
- Abnormal clinical evaluation or family history warrants neuroimaging for headache diagnosis in pediatric patients.
Objectives:
This study aimed to examine headache neuroimaging findings among the pediatric population visiting the emergency department in Saudi Arabia.
Methods:
This was a cross-sectional retrospective study of pediatric patients who presented to the emergency department with a headache as their primary complaint. Data were extracted from the electronic medical files of the patients at King Abdullah Specialized Children Hospital (KASCH) between 2015 and 2020. The diagnosis of headache was confirmed using a computerized tomography (CT) scan or magnetic resonance imaging (MRI) upon the patients' presentation.
Results:
A total of 263 patients met the inclusion criteria, and their data were extracted. The CT scans were abnormal in 50% of the patients. The MRI showed abnormal findings for 26% of the patients. CT scans and MRI identified that abnormalities were predominantly among patients with the secondary type of headache. The most common abnormal findings on CT were sinusitis (16%), masses (7%), and hydrocephalus (7%). The most common abnormal findings on MRI were masses (8%), cysts (5%), and hydrocephalus (3%). Of all patients with headaches, 10% had a prior diagnosis of headache, and 12% had a family history of headache. A significantly higher percentage of patients with secondary headache were prescribed NSAID and required admission compared to patients with primary headache (p ≤ 0.05). There was no statistically significant differences in the proportion of patients diagnosed with primary and secondary headache in terms of their neurological examination and headache types (p = 0.43).
Conclusions:
Neuroimaging is essential for diagnosing headaches in children. Headaches were associated with sinusitis in children. The secondary type was more likely to have abnormal CT and MRI results. Primary type headaches were more common in those with a family history. CT scans and MRIs are needed when a headache is accompanied by an abnormal clinical evaluation. Neuroimaging and mild CT usage may be explored if there are clinical abnormalities or family history.
