Causes of Posterior Headache in Children
Posterior (occipital) headaches in children are most commonly caused by viral infections and primary headache disorders (particularly migraine), not serious intracranial pathology, and should be evaluated based on the presence or absence of neurological signs rather than location alone 1.
Primary vs. Secondary Etiologies
The causes of posterior headaches in children can be categorized into primary and secondary headache disorders 2:
Primary Headache Disorders (Most Common)
Migraine is a frequent cause of occipital headaches in children, occurring in up to 20% of pediatric migraine cases presenting to emergency departments 3. Importantly, occipital location occurs in 7-16% of children evaluated for headache and does not indicate higher risk for serious pathology when the neurological examination is normal 3, 1.
Tension-type headaches account for approximately 30% of pediatric headaches and can present with posterior location 2.
Secondary Causes
Infectious Etiologies (Most Common Secondary Cause)
- Viral upper respiratory infections (39% of acute headaches) 4
- Sinusitis (9%) 4
- Streptococcal pharyngitis (9%) 4
- Viral meningitis (9%) - presents with clear systemic and neurological signs 4
Structural/Neurological Causes (Rare but Serious)
Chiari I malformation is specifically associated with occipital headaches in children, particularly when worsened by Valsalva maneuver. This condition involves herniation of cerebellar tonsils through the foramen magnum and may be associated with syringohydromyelia and scoliosis in children >3 years 2.
Posterior fossa tumors (2.6% of acute headaches) - critically, these virtually always present with objective neurological signs including ataxia, abnormal reflexes, cranial nerve findings, and papilledema (present in 60% of cases) 2, 4.
Intracranial hemorrhage (1.3%) - including subarachnoid hemorrhage from ruptured aneurysm or arteriovenous malformation 4.
Posterior reversible encephalopathy syndrome (PRES) - particularly in immunocompromised children, presenting with hypertension, seizures, and visual disturbances with bilateral parietal and occipital lobe involvement on imaging 5.
Other Secondary Causes
- Pseudotumor cerebri (idiopathic intracranial hypertension) - presents with severe headaches, papilledema, and visual impairments, typically in overweight females but can occur in prepubertal children 2
- Venous sinus thrombosis 2
- Post-traumatic headache (1.3%) 4
- Occipital neuralgia - rare in children, characterized by sharp pain in the GON distribution, often associated with trauma 6
Critical Clinical Distinctions
Red Flags Requiring Investigation
Two clinical features have statistically significant associations with serious underlying disease 4:
- Occipital location PLUS inability to describe headache quality
- Abnormal neurological examination findings (ataxia, hemiparesis, papilledema, abnormal reflexes, cranial nerve abnormalities, gait disturbance)
Reassuring Features
Occipital headaches meeting criteria for primary headache disorders with normal neurological examination have extremely low yield (0-4.1%) for actionable neuroimaging findings 3. The location alone should not trigger concern in the absence of other worrisome features 3, 1.
Common Pitfalls
The most important pitfall is over-attributing significance to occipital location alone. Recent evidence clearly demonstrates that occipital headaches in children with normal neurological examinations are no more likely to represent serious pathology than headaches in other locations 3, 1.
Avoid misdiagnosing migraine with cranial autonomic symptoms (rhinorrhea, nasal congestion) as "sinus headache" - approximately 62% of pediatric migraineurs have these symptoms 2.
Do not skip the complete neurological examination including blood pressure measurement and fundoscopic examination - abnormalities on examination predict neuroimaging findings, while normal examination predicts low yield even with occipital location 2, 3, 4.
