How should a child with a stable intracranial hemorrhage and a new persistent head tilt (torticollis) be evaluated and managed?

Evaluation and Management of Pediatric Intracranial Hemorrhage with New Head Tilt

A child with stable intracranial hemorrhage who develops a new persistent head tilt requires urgent MRI of the brain and cervical spine to exclude posterior fossa tumor, spinal cord tumor, or hydrocephalus, as torticollis is a herald sign of these life-threatening conditions in 22% of pediatric cases. 1

Immediate Clinical Assessment

Perform focused neurological examination looking specifically for:

• Signs of increased intracranial pressure (papilledema, altered consciousness, vomiting) 1
• Cerebellar signs (ataxia, dysmetria, nystagmus) 1
• Cranial nerve palsies, particularly abducens nerve palsy 2
• Focal motor or sensory deficits suggesting spinal cord compression 1
• Fever or neck stiffness suggesting infectious etiology 2

The presence of any additional neurological symptoms beyond isolated torticollis dramatically increases concern for structural pathology requiring immediate intervention. 1

Diagnostic Imaging Algorithm

Order MRI of brain and cervical spine with and without contrast as the primary diagnostic study. 3

• MRI has superior sensitivity for detecting posterior fossa hemorrhages, infratentorial lesions, brainstem pathology, and subacute blood products that become less visible on CT over time 3
• MRI can identify nonhemorrhagic contusions, ischemia, and mass lesions not apparent on prior CT imaging 3
• The patient must be stable enough to tolerate the longer examination time required for MRI 3

If MRI cannot be performed emergently due to instability, obtain CT head immediately to assess for:

• Progressive hemorrhage expansion 3
• Hydrocephalus 3
• Herniation 3
• New mass effect 3

Critical Differential Diagnosis

In the context of known intracranial hemorrhage, prioritize these life-threatening causes:

Structural CNS Pathology (Most Urgent)

• Posterior fossa tumor: Torticollis preceded other neurological symptoms in all 12 pediatric cases where it was the presenting sign, with diagnostic delay averaging 9.6 weeks 1
• Cervical spinal cord tumor: Surgical treatment resolved torticollis in 10 of 11 operated cases 1
• Hydrocephalus: Can develop as complication of intracranial hemorrhage and cause increased intracranial pressure 3
• Cerebellar herniation or tonsillar descent: May occur with posterior fossa pathology 3

Other Serious Causes

• Atlantoaxial rotatory displacement: Most common in older children, typically follows trauma or pharyngeal inflammation (Grisel's syndrome) 2
• Retropharyngeal abscess or pyogenic cervical spondylitis: Present with fever, neck pain, and systemic signs 2

Benign Causes (Diagnosis of Exclusion Only)

• Benign paroxysmal torticollis: Occurs in infants under 3-4 years, episodes last hours to days, resolves spontaneously, but this is inappropriate to consider in a child with known intracranial hemorrhage until structural causes are excluded 4, 5, 6

Management Based on Imaging Findings

If imaging reveals progressive hemorrhage, hydrocephalus, or mass lesion:

• Immediate neurosurgical consultation 3
• Maintain systolic blood pressure 130-140 mmHg, never below 100 mmHg 7
• Elevate head of bed 30 degrees 7
• Hourly neurological assessments using Glasgow Coma Scale 7
• Consider surgical intervention for expanding hematoma, obstructive hydrocephalus, or identified tumor 1

If imaging reveals posterior fossa or cervical spine tumor:

• Surgical resection is definitive treatment and resolves torticollis in 91% of cases 1
• Biopsy for tissue diagnosis if complete resection not feasible 1

If imaging is negative for structural pathology:

• Consider vascular imaging (MRA or CTA) to evaluate for occult vascular malformation or aneurysm 3
• Evaluate for atlantoaxial rotatory displacement with dynamic cervical spine imaging 2
• Assess for infectious causes with inflammatory markers and pharyngeal examination 2

Critical Pitfalls to Avoid

Do not attribute new torticollis to benign causes without comprehensive imaging. The average diagnostic delay of 9.6 weeks in children with CNS tumors presenting with torticollis represents missed opportunities for earlier intervention. 1

Do not rely solely on prior CT imaging. MRI detects subacute hemorrhage, posterior fossa lesions, and spinal cord pathology that CT misses, particularly as blood products evolve over time. 3

Do not assume stability of the original hemorrhage means no new pathology. Torticollis may indicate a completely separate process (tumor, hydrocephalus, vascular malformation) or a complication of the original hemorrhage. 1

Monitoring and Follow-Up

• Continuous monitoring in pediatric intensive care unit with neurosurgical availability 7
• Repeat imaging at 24 hours if initial studies negative but clinical suspicion remains high 7
• Measure hemorrhage volume as percentage of total brain volume in pediatric patients, as smaller brain volumes mean the same absolute hemorrhage has greater impact 3
• Document neurological outcome and ensure appropriate subspecialty follow-up 7
