The MRI and intraoperative situation of a tuberculoma associated with ambient cistern. a Preoperative MRI of the lesion. b Drainage surgery was performed for the first time operation at local hospital with residue mainly at the ambient cistern. c The tuberculoma was relapsed with effective ATT and corticosteroids. d A total resection of the lesion was done. e Intraoperative image showed the clear boundary of the part of tuberculoma situating at cerebellum parenchyma (white arrow). f The intracisternal part of the same tuberculoma demonstrated tightly adhesion to the thickening arachnoid which was relatively difficult for separation (white arrow). g Exposure of a vessel coursed in the subarachnoid space (red arrow)
