case_images: The third ventricle appears to be displaced inferiorly and fourth ventricle appears normal. The major part of the lesion showed restricted diffusion with low-apparent diffusion co-efficient (ADC) values [Figure 5], and peripheral blooming in gradient [Figure 6]. The flow voids of bilateral internal carotid arteries were normal.
case_images: The mass shows blooming in gradient sequence
