Abstract
Background
Posterior fossa epidural hematoma (PFEDH) is rare which accounts for just 4–12.9% of all EDH cases. Since its frequently subtle and nonspecific clinical presentation, CT scan has great importance for early diagnosis and treatment of PFEDH. However, indications for surgery depending on the findings of CT image are still controversial.
Methods
We retrospectively analyzed 40 pediatric cases of PFEDH. Their baseline characteristic, clinical presentation, imaging findings and outcomes were collected and analyzed. The ellipsoid volume equation X × Y × Z/2 was used to measure the hematoma volume. The Glasgow Outcome Scale (GOS) was used to assess the neurologic functional outcome.
Results
A total of 40 pediatric PFEH patients were included with 8 patients having poor outcome and 32 patients having a relatively good prognosis. GCS score showed a significant difference between good and poor outcome groups (p < 0.001). Y value on CT image was significantly bigger in poor outcome group than good outcome group (p < 0.01). Similar results were got in X/Z value (p < 0.05) and Y/Z value (p < 0.01) which reflected the shape of hematoma. A predictive model with Y + X/Z showed the largest area under the ROC curve with a sensitivity of 75.0% and specificity of 93.7%.
Conclusions
GCS score at admission was closely related to the prognosis of the pediatric patients with PFEDH. The morphometry of PFEDH has a crucial role in judging the prognosis. Axial convex-shaped hematoma was associated with poor curative effect of surgical treatment.
