However, CT performed 1 day later showed a massive subcutaneous hemorrhage appearing as acute epidural hematoma (AEDH) [Figure 3a]. CT on postoperative day 1 revealed a small persistent hematoma and improved median deviation [Figure 3b].
CT imaging findings after cranioplasty. A small amount of air is the sole abnormal finding immediately after cranioplasty (a). Epidural hematoma is evident under artificial bone at 22 hours after cranioplasty (b)
