 Images are slightly limited by patient motion. There is a stable right frontal approach ventriculostomy catheter with its tip terminating in the region of the right foramen of Monro. There is susceptibility artifact resulting from the ventriculostomy catheter, limiting evaluation of surrounding structures. There is persistent moderate prominence of the lateral ventricles.There is suggestion of the third ventriculostomy defect, with a small T2 hypointense flow-void extending through this area implying patent ventriculostomy. Phase contrast images demonstrate conspicuous bidirectional CSF flow through the third ventriculostomy site. There is no significant flow detected through the aqueduct which is again narrowed without proximal funneling.A few foci of nonspecific T2/FLAIR hyperintensity are again seen in the left frontal periventricular white matter. There is minimal persistent gliosis along the ventriculostomy catheter. Again noted is a focus of susceptibility in the right inferior medial frontal lobe. The previous focus in the right brachium pontis is not well visualized. Small pineal cyst with fluid-fluid level is unchanged. Aerated secretions are noted in the left sphenoid sinus.
Continued stable exam with patent third ventriculostomy and stable moderate dilatation of the lateral ventricles. Stable right frontal approach ventriculostomy catheter.
