Presentation
History of R.T.A before 2 years, the patient now complains of right abducens nerve palsy and chronic headache.
Patient Data
Evidence of right-sided VP shunt, its tip is seen in the anterior body of the corpus callosum, with slit right lateral ventricle and mildly dilated left lateral ventricle, suggesting over-drainage of the right lateral ventricle and under-drainage of the left lateral ventricle, it is associated with distention of the dural sinuses.
Features are suggestive of slit ventricle syndrome.
T2/FLAIR high signal intensities of the body of corpus callosum and in bilateral periventricular white matter are noted, likely sequela from the previous trauma.
No ICH, space-occupying lesion or shift of midline structures.
Normal brain stem.
Normal arterial and venous flow voids.
No restricted diffusion.
Both cerebellopontine angles are clear.
No tonsillar herniation.
Both mastoids are clear.
Case Discussion
Slit ventricle syndrome is an entity with a triad of intermittent headaches, slowly refilling shunt reservoir on physical examination and “slit" ventricle on radiographic examination.
Vomiting and cranial neuropathies are well known symptoms.
