Cerebellar Ataxia - Neuropathy - Vestibular Areflexia Syndrome

CANVAS Syndrome


  • We present a case of 58-year-old male patient who has demonstrated gait disturbance, imbalance and paresthesia of feet for 2 years.[ncbi.nlm.nih.gov]

  • An impaired or saccadic vVOR suggests that there is failure of both the pursuit and (bilateral) vestibular systems, and CANVAS should be considered, especially when neuropathy is present.[collections.lib.utah.edu]
  • Thirteen patients presented with gait imbalance, 8 of whom noted this to be worse in the dark. Two patients reported dizziness on presentation, while only one patient gave an account of intrinsic falls.[docplayer.net]
Streptococcal Infection
  • Van Stavern, MD, Associate Professor, Ophthalmology & Visual Sciences and Neurology, Washington University School of Medicine Description A 67 year old woman presented with 1 year of progressive numbness, gait instability, and oscillopsia when walking[collections.lib.utah.edu]
  • Oscillopsia is the blurring and inability to focus on objects whilst moving. It manifest as the difficulty to read road signs when driving or recognize faces when walking. Oscillopsia occurs when both the vestibulo ocular reflexes (VOR) fail.[lmhofmeyr.co.za]
  • A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR).[readbyqxmd.com]

Positive Romberg Sign
  • All patients showed gait and limb ataxia, positive Romberg sign, cerebellar dysarthria, gaze-evoked nystagmus, absent deep tendon reflexes, and impaired vibratory sensation.[ncbi.nlm.nih.gov]
  • It should be noted that the finding of a positive Romberg sign may reflect functional impairment of either or both vestibular and proprioceptive function, a point which is particularly relevant to a condition which comprises defects in both of these systems[docplayer.net]

  • Symptoms can be precipitated by hyperventilation, and workup includes an MRI, as certain heavily T2 weighted sequences can show a blood vessel compressing the 8 th cranial nerve in the CPA (cerebellopontine angle) or the IAC (internal auditory canal).[ohns.ucsf.edu]

MRI Scan showing Cerebellar Atrophy
  • MRI scans showed cerebellar atrophy in 16, involving anterior and dorsal vermis, and hemispheric crus I, while 2 were normal. The inferior vermis and brainstem were spared. Sensory neuropathy is an integral component of this syndrome.[ncbi.nlm.nih.gov]
  • MRI scans showed cerebellar atrophy in 16, involving anterior and dorsal vermis, and hemispheric crus I, while 2 were normal. The inferior vermis and brainstem were spared. Conclusions: Sensory neuropathy is an integral component of this syndrome.[docplayer.net]
