Cystic dilation of the ventriculus terminalis.
The ventriculus terminalis (VT) is a virtual cavity of the conus medullaris that appears during embryonic life. We presented a case with the cystic dilation of the ventriculus terminalis (CDVT) in a symptomatic patient. A 66-year-old female suffered from disturbance while walking evolving for the past 2 years. An MR image revealed a cystic dilatation of ventriculus terminalis. The patient experienced marked improvement of lower extremity strength by a fenestration of cyst and cyst-subarachnoid shunt. Treatment for asymptomatic patients seems to be the best conducted conservatively, whereas patients with focal neurological deficits seem to be best handled surgically.
