Fig. 2. Radiological images of a postoperative hematoma. A well-enhanced extra-axial mass with extensive edema was found on the right middle parasagittal region (A and B). Postoperative hematoma was developed (C). The motor symptoms were aggravated plegia of the left ankle and a subtle weakness of the arm. In a magnetic resonance imaging scan, a rim-enhancing mass was found at the hematoma area 2 months after the surgery (D). The abscess was drained.
