case_images: Axial non-contrast CT scan reveals a relatively well-demarcated frontoparietal tumor with mixed densities, with solid and cystic areas and minimal peripheral edema, but displacement of midline structures

case_images: There was midline shift observed and collapse of the ipsilateral ventricular system as well [Figure 1].
case_images: Axial T1-weighted (a) and contrast (b) MRI demonstrates a heterogeneous well-circumscribed frontoparietal tumor with rim enhancement and enhancement of the solid and cystic areas of the tumor

case_images: T1-weighted images it was heterogeneous, but predominantly isointense to white matter [Figure 2]. The T2-weighted images revealed a multicystic hyperintense lesion with a striking "bubbly" heterogeneous pattern inside the tumor [Figure 3]. Contrast images revealed a mixed solid and peripheral rim enhancement [Figure 2].
case_images: Axial T2-weighted MRI shows a heterogeneous, predominantly hyperintense lesion with white matter, with minimal surrounding edema and "bubbly" appearance (a). Coronal T2- weighted MRI reveals a strikingly "bubbly" appearance and midline shift (b)

case_images: Histopathologic analysis revealed a papillary neoplasm composed of mildly pleomorphic cells with a striking perivascular array of pseudorosettes (a, 10x). Also, prominent endothelial hyperplasia and hyalinized vessel walls were found (b, 4x) (hematoxylin/eosin)
