Traumatic Retroclival Epidural Hematoma

Pediatric retroclival hematomas

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.

Management of traumatic cervical epidural hematoma in patients on Xa-inhibitors: a case report and review of the literature

BACKGROUND

Cervical epidural hematoma (CEH) is defined as a collection of blood in the suprameningeal space. Mechanisms of this rare pathology include spontaneous, postsurgical, and traumatic as the main subtypes. This unique case of traumatic CEH represents an even smaller subset of these cases. Management varies by symptom presentation, mechanism of injury, and other contraindications.

CASE PRESENTATION

This case presents a 32 year old African American female on an oral anticoagulant sustaining traumatic cervical hematoma after a motor vehicle collision. Patient complained of neck, abdominal, and back pain. Imaging revealed a cervical spinal hematoma at the level of C3-C6. This case discusses the management of CEH for the general population and in the setting of anticoagulation.

CONCLUSION

Management of each case of CEH must be carefully considered and tailored based on their symptom presentation and progression of disease. As the use of anticoagulation including factor Xa inhibitors becomes more prevalent, there is greater need to understand the detailed pathophysiological aspect of the injuries. Targeted reversal agents such as Prothrombin Concentrate can be used for conservative treatment. Adjunct testing such as thromboelastogram can be used to help guide management.

Isolated Retrodental Epidural Hematoma Without Dens Fracture

BACKGROUND

Traumatic spinal epidural hematomas (TSEDH) are rare, with the reported incidence being < 1% of all spinal injuries. Causes of TSEDHs include vertebral fractures, obstetrical birth trauma, lumbar punctures, postsurgical bleeding, epidural anesthesia, and missile injuries. The retrodental location has not been reported as a location for spontaneous epidural hematoma.

CASE REPORT

A 4-year-old boy was admitted to our Emergency Department after falling down and experiencing head trauma. Glasgow Coma Scale score was 15/15 with no neurologic deficit. Brain computed tomography scan showed isolated hyperdense hematoma in the retrodental area without any fractures in the skull or cervical vertebrae. Brain and cervical magnetic resonance imaging showed a retrodental acute hematoma that was isointense in T1-weighted sequences and hypointense in T2-weighted sequences. The hematoma was in the epidural space with possible odontoid process intracapsular origin. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Isolated retrodental epidural hematoma without dens fracture is an extremely rare pathology and finding, and to the best of our knowledge, this is the first case to be reported in the literature. Emergency physicians should consider this pathology for any patients presenting for head trauma with head hematoma.
