Transient Postural Vestibulo-Cerebellar Syndrome is a condition that present as pronounced vestibulo-cerebellar signs. In this syndrome transient postural symptoms present as vestibulo-cerebellar signs after altering the position of the head.Vestibular deficits related to head posture have been described, introducing the relationship of nodulus and uvula pathology to various vestibular signs elicited by the postural changes of the head.
Case report:
Signalment: Adopted from a shelter mix breed female dog without previous history.The age of the dog was estimated to be 7-8 months based on general appearance and teeth condition.
Case presenting sings: Vestibular episodes during sniffing and eating or head position changing(Transient vestibular signs as vertigo and nystagmus caused by changing the posture of the head). Symptoms are not progressive.
Clinical examination: Good overall condition ; Internal body temperature- 38,9; Normal respiratory and heart rate; Color of mucous membranes – pink; CRT – 1,5 sec.
Neurological examination:
Mentation: Normal
Behavior: Normal
Gait: Normal( no signs of cerebellar ataxia when the dog plays or runs)
Cranial nerves: normal
There was no change in conscious proprioception and bladder function was normal.
Spinal reflexes were normal.
Neuroanatomic localisation: Vestibulocerebellum
Differential diagnosis: Idiopatic/Anomaly/Metabolic/Degenerative/Neoplastic/Trauma/Vascular
Case work-up:
CBC and Biochemistry- without any changes
CRP – 8,7 my/L
Magnetic resonance of the head was performed with GE MRI 1.5 Tesla.
MRI findings:
The T1W and T2W sagittal and transversal images showed reduced size of the nodulus and uvula of the caudal cerebellum with CSF filling the space normally occupied by cerebellar parenchyma.This is particularly visible on T2W images due to the hyperintensity of the surrounding CSF.These imaging findings were considered most likely to represent congenital caudal cerebellar hypoplasia.
There is no histopathological examination providing a definitive diagnosis, but the most likely diagnosis is Congenital Caudal Cerebellar Hypoplasia.
No treatment was recommended. There is no progression of the clinical sings 4 months after the examination.
