Upbeat Nystagmus

Abstract Introduction CNS cavernomas are a type of raspberry-shaped vascular malformations that are typically asymptomatic, but can result in haemorrhage, neurological injury, and seizures. Here, we present a rare case of a brainstem cavernoma that was surgically resected whereafter an upbeat nystagmus presented postoperatively. Case report A 42-year old man presented with sudden-onset nausea, vomiting, vertigo, blurred vision, marked imbalance and difficulty swallowing. Neurological evaluation showed bilateral ataxia, generalized hyperreflexia with left-sided predominance, predominantly horizontal gaze evoked nystagmus on right and left gaze, slight left labial asymmetry, uvula deviation to the right, and tongue deviation to the left. MRI demonstrated a 13-mm cavernoma with haemorrhage and oedema in the medulla oblongata. Surgery was performed via a minimal-invasive, midline approach. Complete excision was confirmed on postoperative MRI. The patient recovered well and became almost neurologically intact. However, he complained of mainly vertical oscillopsia. The videonystagmography revealed a new-onset spontaneous upbeat nystagmus in all gaze directions, not suppressed by fixation. An injury of the rarely described intercalatus nucleus/nucleus of Roller is thought to be the cause. Conclusion Upbeat nystagmus can be related to several lesions of the brainstem, including the medial longitudinal fasciculus, the pons, and the dorsal medulla. To our knowledge, this is the first case of an iatrogenic lesion of the nucleus intercalatus/nucleus of Roller resulting in an upbeat vertical nystagmus. For neurologists, it is important to be aware of the function of this nucleus for assessment of clinical manifestations due to lesions within this region.

IntroductionThe diagnosis of vestibular disorders may be facilitated by analysing patient-initiated capture of ictal nystagmus.MethodsAdults with a history of recurrent vertigo were taught to self-record spontaneous and positional-nystagmus at home while symptomatic, using video-goggles. Patients with final diagnoses of disorders presenting with recurrent vertigo were analysed: 121 patients with Ménière’s Disease (MD), Vestibular Migraine (VM), Benign Positional Vertigo (BPV), Episodic Ataxia Type II (EAII), Vestibular Paroxysmia (VP) or Superior Semicircular Canal Dehiscence (SSCD) were included.ResultsOf 43 MD patients, 40 showed high-velocity spontaneous horizontal-nystagmus (median slow-phase velocity (SPV) 39.7 degrees/second (°/s); Twenty-one showed horizontal-nystagmus reversing direction within 12-hours (24 on separate days). In 44 of 67 patients with VM, low velocity spontaneous horizontal (n=28, 4.9°/s), up-beating (n=6, 15.5°/s) or down-beating-nystagmus (n=10, 5.1°/s) was observed; Sixteen showed positional-nystagmus only, and seven had no nystagmus. Spontaneous horizontal-nystagmus with SPV >12.05°/s had a sensitivity and specificity of 95.3% and 82.1% for MD. Nystagmus direction-change within 12-hours was highly specific (95.7%) for MD. Spontaneous vertical-nystagmus was highly specific (93.0%) for VM. In the seven BPV patients, spontaneous-nystagmus was absent or <3°/s, and characteristic paroxysmal positional nystagmus was observed in all cases. Patients with central and MD-related positional vertigo demonstrated persistent nystagmus. Two patients with EAII showed spontaneous vertical nystagmus, one patient with VP showed short bursts of horizontal-torsional nystagmus lasting 5–10s, and one patient with SSCD demonstrated paroxysmal torsional down-beating nystagmus when supine.ConclusionsPatient-initiated vestibular event-monitoring is feasible and could facilitate rapid and accurate diagnosis of episodic vestibular disorders.
