Non-contrast head CT showing bilateral basal ganglia hemorrhages. (A) Hemorrhage volume was about 18 mL on the right and 27 mL on the left side. (B) Markers applied to the patient's head before MIS to indicate puncture points and allow tracking. Hemorrhage volume was about 19 mL on the right and 29 mL on the left side. (C, D) Immediate postoperative head CT scan showing a reduced hematoma volume. Hemorrhage volume was about 14 mL on the right and 11 mL on the left side. (E, F) Postoperative day 3 CT scan showing residual clots (10 mL on the right and 2 mL on the left side). (G, H) Postoperative day 19 CT scan showing that the intracranial hematoma was absorbed.

Head CT showed bilateral basal ganglia hemorrhages of about 18 mL on the right and 27 mL on the left side (Figure 1A). We pasted CT markers on the frontal and temporal areas of the patient's head for head CT to indicate the puncture points for aspiration (Figure 1B). Immediate postoperative head CT confirmed the catheter track and residual hematomas (Figure 1C and D). On postoperative day 3, head CT showed a residual clot (10 mL on the right and 2 mL on the left side) and the patient was extubated (Figure 1E and F). On postoperative day 19, the ventilator was removed and head CT revealed absorption of the intracranial hematoma (Figure 1G and H).
