case_images: Preoperative FLAIR axial imaging showing a 5.6 cm cystic lesion in the right cerebellar hemisphere, with the lesion draining the fourth ventricle and brainstem, resulting in obstructive hydrocephalus (a and b). T2 coronal image showing a mural nodule in the cyst (white arrow) (c).

case_images: Intraoperative view showed that the dura was incised and a mural nodule was identified directly underneath (a). The tumor was punctured and the pale yellow contents were aspirated; internal decompression was performed (b). The mural nodule was removed as a mass without resecting the cystic capsule and it was confirmed that the cerebellum had become slack and pulsation was observed (c). Histopathological examination of the specimen revealed a rich vascular network (white arrow) and bubbly vacuolated cells with mild nuclear enlargement and clear cytoplasm (arrowhead) (d).

case_images: Following cyst decompression and tumor resection without resecting cystic capsule, it was confirmed that the cerebellum had become slack and pulsation was observed [Figures 2a-c]. Histopathological examination of the specimen confirmed hemangioblastoma [Figure 2d].
case_images: Postoperative FLAIR axial imaging showing that the tumor was successfully removed with no obvious residual tumor, and T2 coronal imaging showing that the hydrocephalus had improved (a-c).

case_images: Postoperative brain MRI revealed that the tumor had been removed with no obvious residual tumor and the hydrocephalus had improved [Figures 3a-c].
