“…In this study, both groups of BPPV showed partial vHIT abnormalities, lacking correlation with responsible semicircular canals, and there was no difference between groups. This is similar to previous research results ( 11 , 12 ). Idiopathic BPPV can be seen with scattered semicircular canal injury, and ectopic otolith is not the main cause of its injury.…”

ObjectiveTo analyze and compare the vestibular function of posterior canal cupulolithiasis and canalolithiasis.MethodsThe results of posterior cupulolithiasis in 45 cases, posterior canalolithiasis in 122 cases and 19 healthy controls were analyzed retrospectively.ResultsThe abnormal rates of vHIT in the canalolithiasis group and the cupulolithiasis group were 42.6 and 37.8%, respectively, both higher than those in the control group (both p < 0.05); there was no statistically significant difference between two BPPV groups (p = 0.573). The abnormal vHIT in 76.9% of the canalolithiasis cases and 82.4% of the cupulolithiasis cases showed normal gain with saccades, with no difference between the groups (p = 0.859). The lesion location of vHIT in the two groups did not show a correlation with the affected side of BPPV (both p > 0.05). 84.4% of canalolithiasis and 65.0% of cupulolithiasis had abnormal VEMP results, with no significant differences in abnormality rates or sides (both p > 0.05). Abnormal results of VEMPs did not show any correlation with side (p > 0.05). The results of pc-ca and pc-cu were both abnormal in 14 cases and 7 cases, and there was no correlation between the site and side of the injury (all p > 0.05).ConclusionThe results of vHIT and VEMP in pc-cu and pc-ca were partially abnormal, but they did not show any correlation with side of BPPV. It can be considered that there are scattered vestibular peripheral organ damage in both groups.

“…Other relevant clinical signs that were present during the vestibular examination that contributed to the treatment decision included the low-normal gain with covert and overt saccades on vHIT for the right posterior semicircular canal. There are several studies12 15 16 that suggest the use of vHIT does not aid in identification of the involved semicircular canal in cases of BPPV. However, a recent study by Castellucci et al 17 did use vHIT to detect the involved semicircular canal in BPPV for positional downbeat nystagmus that is commonly associated with little or no torsion.…”

This case demonstrates the successful identification and treatment of atypical posterior semicircular canal benign paroxysmal positional vertigo (BPPV) based on a unique presentation of positional nystagmus, the resultant nystagmus from repositioning manoeuvers, and restored function of the affected semicircular canal. This case illustrates the importance of completing a comprehensive clinical examination and the value for incorporating the video head impulse test as well as adjusting treatment based on testing and patient response when managing variant cases of BPPV.
