case_images: (A) axial T1-weighted MRI (B) sagittal T1-weighted MRI demonstrate a large intraparenchymal cystic mass with low signal intensity, located in the right frontoparietal region of the right cerebral hemisphere.

case_images: Minimal micro bleed is identified within the septation (Figures 1, 2).
case_images: (A) Magnetization prepared rapid acquisition gradient echoes (MPRAGE) axial T1-weighted contrast-enhanced MRI, (B) sagittal T1-weighted contrast-enhanced MRI, (C) coronal T1-weighted contrast-enhanced MRI demonstrate a well-defined oval-shaped lesion that is homogeneously enhancing located at the lateral aspect of the mass.

case_images: Minimal micro bleed is identified within the septation (Figures 1, 2).
case_images: (A) The nodule in the cyst is formed by vascular neoplasm (arrow). The cyst wall (arrow's head) is formed by reactive glial tissue. (B) The neoplasm is formed by cellular, and back-to-back capillary-size vascular spaces. Plumb endothelial cells with no atypia line these spaces. Haematoxylin & Eosin stain.

case_images: Histopathology confirmed the diagnosis of infantile hemangioma with positive CD31 on immunohistochemistry (Figure 3). 
case_images: Postoperative T1-weighted MRI brain Coronal (A) Axial (B) Sagittal (C) views shows significant decompression of the large right cerebral cystic mass with almost no mass effects identified in the current MRI examination and no midline shift with normal configuration of the supratentorial and infratentorial ventricular system. Resection of the previously visualized well-defined rounded solid mass with no residual identified in the current MRI examination. Multiple hemorrhagic spots, pneumocephalus and mild subdural fluid are identified related to operative interference.

case_images: FIG4
case_images: MRI brain postoperatively was done and showed complete resection of the solid portion of the tumor with no residual and partial decompression of the large cystic component with resolution of the mass effect (Figure 4).
