case_images: CT scanning before the new therapeutic regimen showed a round cystic-solid lesion in the operative area, with the interior of the lesion being hypointense and the surrounding solid cystic wall being hyperintense. The brain tissue around the lesion was evidently edematous.

case_images: The brain tissue around the lesion was evidently edematous ( Figure 1 ).
case_images: Results of MRI before the new therapeutic regimen. T2 scanning showed that the T2 signal from the interior of the lesion was long, while that from the surrounding cystic wall was short. Enhanced MRI scanning showed significant enhancement along the surgical path. The lesion localized in the surgical area formed a complete cystic wall and was significantly enhanced.

case_images: Enhanced MRI of the head showed significant enhancement of all brain parenchyma along the surgical path, and the lesion localized in the surgical area formed a complete cystic wall, which exhibited significant central enhancement ( Figure 2 ).
case_images: CT scanning results after treatment with the new regimen for 14 days showed that the abscess had disappeared and that there was little edema in the surrounding brain tissue.
