    Figure 1.

    Dorsal midbrain cavernous malformation demonstrating classic popcorn appearance. Axial T2 gradient echo image (A) shows prominent susceptibility artifact indicating blood products (arrow). Axial T2-weighted image (B) depicts heterogeneous signal centrally with hypointense hemosiderin rim (arrow). No surrounding edema. T1-weighted images before (C) and after (D) intravenous contrast administration show minimal postcontrast enhancement of the lesion (arrows).

  • Figure 2.
    Figure 2.

    Diffusion tensor imaging with tractography fractional anisotropy maps with (A) and without (B) directional color information showing effacement of the superior cerebellar peduncle and mild displacement of the medial lemniscus (arrows). Transverse pontine fibers and pyramidal tract are intact anterior to the lesion. Three-dimensional sagittal (C) and coronal (D) tractograms of the left corticospinal tract demonstrate the relationship of the cavernous malformation to traversing white matter bundles.
