  • Figure 1
    CT on admission
     

    Axial NECT showing a large intraventricular heterogeneous cauliflower-like mass with surrounding oedema, left occipital horn encystment and mass effect with right-sided midline deviation.

     
    Area of Interest: Neuroradiology brain; Oncology; Imaging Technique: CT; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial CECT showing the lesion is markedly enhancing, suggesting hypervascularity.

  • Figure 2
    MRI made after placement of ventricle drain
     

    Axial T2-weighted image. The lesion in the trigone of the left lateral ventricle is heterogeneous. There is surrounding periventricular white matter oedema.

     
    Area of Interest: Neuroradiology brain; Oncology; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial FLAIR image. The lesion in the trigone of the left lateral ventricle is heterogeneous and there is surrounding periventricular white matter oedema.

     
    Area of Interest: Neuroradiology brain; Oncology; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial contrast-enhanced T1 image. The lesion in the trigone of the left lateral ventricle is heterogeneous and shows a strong heterogeneous contrast enhancement.

     
    Area of Interest: Neuroradiology brain; Oncology; Imaging Technique: MR; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Axial diffusion-weighted image showing restricted diffusion in the lesion.

     
    Area of Interest: Neuroradiology brain; Oncology; Imaging Technique: MR-Diffusion/Perfusion; Procedure: Diagnostic procedure; Special Focus: Neoplasia;

    Apparent diffusion coefficient image showing low ADC values in the lesion.

    Sagittal contrast-enhanced T1-weighted images of the neuroaxis made 6 months after the surgical resection showing new brain and leptomeningeal metastases.
