Abstract

A 61-year-old patient presented with a sudden onset of chronic dizziness 4 months ago. His symptoms included intermittent nausea and dizziness. The left Hallpike-Dix test causes the patient to feel dizzy and nauseous. Weak left torsion nystagmus lasting about 10 s was also observed. The right head suspension (HH) test was then performed and it produced some strong left torsion nystagmus lasting about 30 s. The patient was diagnosed with left anterior renal tubular stone disease, which is a type of benign paroxysmal postural vertigo (BPPV). Deep head suspension (DHM) was performed and the patient reported feeling better soon after. The HH test was repeated within minutes and the patient reported 80% relief of dizziness and nausea. The patient was seen the next day and reported 100% resolution of symptoms. Her symptoms still resolved after a week of follow-up. Based on the limited research on the testing and intervention methods described in this single-topic case report, further research, including controlled clinical trials, is warranted.
