Abstract
Background
Traumatic retroclival hematomas (RCHs) are infrequent occurrences among the pediatric population. The existing body of research pertaining to these hematomas primarily consists of case reports or small case series, which do not provide adequate guidance for managing this condition.
Objective
This study aims to present a report on four cases of RCHs. Additionally, we aim to conduct a systematic review to consolidate the existing literature on pediatric RCHs.
Methods
The authors conducted a systematic review in accordance with the PRISMA and CARE guidelines. A multivariate logistic regression model was developed to evaluate the potential impact of various clinical variables on clinical outcomes. The study also documented four of our cases, one of which was a rare occurrence of spontaneous subdural RCH.
Results
A total of 62 traumatic RCHs have been documented in the literature. We documented three cases of traumatic RCHs and one case of spontaneous RCH. A systematic analysis of 65 traumatic RCHs was performed. Of trauma cases, 64.6% demonstrated craniocervical junction instability with 83.3% ligamentous involvement. Thirty-five patients were males. 50.7% were aged between 5 and 9 years. Cranial nerve palsies occurred in 29 patients (27 had abducent palsy), 26 of which resolved within 6 months of trauma. 23.5% underwent surgery, and 76.5% were conservatively managed. Surgeries targeted hematomas, hydrocephalus, or craniocervical instability. Approaches to hematomas included transclival and far/extreme lateral suboccipital approaches. Clinical outcome was good in 75.4% and intermediate or poor in 24.6%. Logistic regression suggested an association between craniocervical junction injuries and poor or intermediate outcomes (OR 4.88, 95% CI (1.17, 27.19), p = 0.04).
Conclusion
Pediatric RCHs are mostly traumatic and extradural. Children between 5 and 9 years old are most vulnerable. Craniocervical junction injuries, mainly ligamentous, are common in RCHs and are associated with intermediate or poor outcomes. Cervical MRI could be important in cases of trauma to rule out ligamentous injuries of the craniocervical junction. The small size of RCHs should not exempt the careful assessment of craniocervical junction instability. Cranial nerve palsies are common and usually resolve within 6 months. Conservative treatment is typical unless brainstem compression, hydrocephalus, or craniocervical junction instability exists.
