case_images: Brain magnetic resonance imaging. Axial brain contrast material-enhanced T1-weighted image. Within the fourth ventricle, there is a well-defined lesion, homogenous enhancement, and causing partial obliteration of the fourth ventricle.

case_images: A 48-year-old male with a history of fourth ventricle atypical CPP diagnosed in 2008 underwent gross total resection (GTR) without any postoperative neurological deficits [Figure 1].
case_images: Spinal magnetic resonance imaging. (a) Sagittal T2-weighted image (b) sagittal lumbar spine contrast material-enhanced T1-weighted image (c) coronal T2-weighted image (d) axial lumbar spine contrast material-enhanced T1-weighted image. In the vertebral canal at the level of the intersomatic space, L3L4 presents a well-defined ovoid lesion, isointense on T2 sequence, with a length of 1.7 x 1.2 cm, and intradural-extramedullary behavior that involves the spinal canal with homogeneous enhancement.

case_images: Spinal magnetic resonance imaging revealed a well-defined intradural ovoid lesion in the vertebral canal at the level of the L3-L4 intersomatic space with a length of 1.7 x 1.2 cm that was isointense on T1 and T2 sequences with homogeneous enhancement [Figure 2].
