We present an extremely unusual acute presentation of a paediatric vertebral haemangioma. This study highlights the need for early diagnosis, MRI for investigation and urgent surgical management.

Background: Platelet inhibitors are used to prevent thromboembolic complications related to neurovascular stenting (NVS) procedures. Despite substantial inter-individual variability of functional platelet inhibition, the value of platelet function tests (PFT) to assess inhibition remains controversial. Objective: This study was conducted to compare differences in thromboembolic complication rates associated with NVS in platelet-inhibited patients with and without PFT. Clinical neurological outcomes were assessed by differences in the modified Rankin Scale (mRS). Materials and Methods: One hundred seventeen consecutive patients underwent elective NVS procedures within a 7-year period. All patients received aspirin and clopidogrel 8 days before the procedure. Fifty-two patients were treated without assessment of platelet inhibition, and 65 patients were tested for clopidogrel resistance. When clopidogrel resistance was revealed, corresponding patients were converted to ticagrelor. Changes in mRS and thromboembolic event rates were compared between the 2 cohorts. Results: Thirty-five percent of patients from the cohort subjected to PFT tests showed inadequate platelet inhi­bition under clopidogrel and were converted to ticagrelor. Compared to the non-PFT test ­cohort, neurological deficits were significantly reduced (12 vs. 0%; p = 0.009) and a lower number of thromboembolic events was found (12 vs. 3%; p > 0.05) within the test cohort. Conclusion: PFT appears to identify patients with clopidogrel resistance prior to NVS procedures. When non-responders are converted to alternative platelet inhibitors, neurological outcomes and thromboembolic complication rates may improve. Consequently, this study provides preliminary evidence that PFT may be a useful clinical tool to enhance procedural safety and improve clinical outcomes in NVS procedures.

Traumatic pneumatoceles are a rare complication of blunt chest trauma in children. Although they characteristically present as small, regular shaped lesions which can be safely treated nonoperatively, larger traumatic pneumatoceles pose diagnostic and management difficulties for clinicians. This case study reports one of the largest traumatic pneumatoceles reported to date in the paediatric population, which resulted in aggressive surgical intervention for both diagnostic and treatment reasons. This case adds further evidence to the current literature that significantly large traumatic pneumatoceles with failure of initial conservative management warrant surgical exploration and management to optimise recovery and prevent complications.
