Sagittal MR myelogram (above left) shows leakage of hyperintense cerebrospinal fluid into the soft tissues inferior to the cerebellum, which lateralizes to the left side on the coronal MR myelogram (above right). Sagittal T2 MRI without contrast of the brain (below) shows the tear in the linear hypointense dura with the hyperintense cerebrospinal fluid leaking through it just inferior to the tip of the cerebellar tonsil.
