case_images: Brain magnetic resonance imaging (MRI). Images on the left belong to the initial examination with a 3-T Ingenia Philips MRI. Images on the right are from the follow-up examination with a 1.5-T Achieva dStream MRI. Follow-up examination images contain artifacts because deterioration of the clinical status and poor patient compliance allowed only a shortened modified MRI protocol. The upper images show subarachnoid leptomeningeal enhancement of contrast medium along the central sulcus (arrow) through leptomeningeal carcinomatosis. The lower right image demonstrates cerebrospinal fluid flow obstruction resulting in hydrocephalus with widening of the third ventricle (arrow), triangular widening of the lateral ventricles and transependymal diapedesis (arrow).

case_images: MRI was repeated, showing progressive widening of the third ventricle, compatible with CSF flow obstruction and hydrocephalus (Figure 1).
