Article Figures & Data

Figures

  • FIGURE 1.
    FIGURE 1.

    Planar images 30 min after injection of 111In-DTPA confirm radiotracer activity in subarachnoid space, with cephalad migration up spinal column.

  • FIGURE 2.
    FIGURE 2.

    Anterior, posterior, and lateral planar images 4 h after injection demonstrate reflux of radiotracer into lateral ventricles.

  • FIGURE 3.
    FIGURE 3.

    Planar images 24 h after injection show persistent reflux into ventricles, with no flow over convexities. Shown clockwise from top left are axial, posterior, anterior, right lateral, and left lateral projections of head and neck.

  • FIGURE 4.
    FIGURE 4.

    SPECT/CT images at 24 h using Smart color map (Philips) in axial (A), sagittal (B), and coronal (C) reconstructions demonstrate reflux into lateral ventricles in butterfly, comma, and heart configurations, respectively. Additionally, coronal images demonstrate radiotracer activity localized to Sylvian fissures.
