case_images: Plain CT scans on admission demonstrate that a hypodense crescentic fluid collection enlarged and extended over the surface of the left cerebral hemisphere. The fluid cavity was loculated, suggesting repeated hemorrhage in the subdural space. The midline structures of the brain were shifted to the right side.

case_images: The midline structures of the brain were shifted to the right side (fig. 1).
case_images: Plain CT scans show the recurrence of the left chronic subdural hematoma 1 month after the first burr hole surgery (a) and 1 week after the second burr hole surgery (b).

case_images: Follow-up CT scans taken one month after surgery, however, showed that the subdural fluid collection enlarged again (fig. 2a). Although he was neurologically intact, subdural fluid collection increased in volume again 1 week after the second surgery (fig. 2b).
case_images: a Plain CT scans demonstrate the recurrence of the left infected subdural hematoma 1 month after the embolization of the MMA. Note the low-density area in the left frontal lobe adjacent to the overlying hematoma. b Plain CT scans reveal that the volume of the left infected subdural hematoma increased again during 2 weeks after the third burr hole surgery.

case_images: One month later, follow-up CT scan revealed that the subdual hematoma further enlarged, and the low-density area developed in the left frontal lobe (fig. 3a). However, the infected subdural hematoma increased in volume during 2 weeks after the third burr hole surgery (fig. 3b), and the patient underwent large frontotemporal craniotomy.
case_images: a Plain CT scans demonstrate that the left infected subdural hematoma recurred quickly 3 days after the first craniotomy surgery. b Plain CT scans show a complete disappearance of the infected subdural hematoma about 5 months after the second craniotomy surgery. Note the disappearance of the low-density area in the left frontal lobe.

case_images: However, the volume of the infected subdural hematoma increased again 3 days later (fig. 4a). Plain CT scan showed complete disappearance of the infected chronic hematoma (fig. 4b).
