case_images: Computed tomography (CT) scan revealed fluid collection in the right maxillary paranasal sinus [Figure 1a]. However, there were no abnormal findings in the cranium [Figure 1b and c].
case_images: (a and b) First, computed tomography scan revealed right subcortical hematoma. (c) Second, computed tomography scan revealed that hematoma did not expand; however, midline-shift caused by brain edema was slightly worsened. Red dotted lines indicate the median. (d) Postoperative computed tomography revealed complete removal of hematoma

case_images: Size of hematoma was 40 mm x 50 mm x 60 mm, and its volume was approximately 60 cc [Figure 2a and b]. Secondary CT scan conducted after 3 h did not illustrate the expansion of hematoma but showed slight aggravation of midline-shift caused by brain edema [Figure 2c]. Postoperative CT scan revealed complete removal of hematoma and improvement of midline-shift [Figure 2d].
