cerebellar infarction vertigo acute vestibular syndrome
I now have comprehensive information. Let me synthesize the full clinical analysis.
Clinical Analysis: 58M — Acute Vertigo → Persistent Imbalance
Interpreting the Presentation
| Feature | Finding |
|---|---|
| Age/Sex | 58M — vascular risk age |
| Episode | Sudden severe vertigo ("chakkar") × 4–5 hours + vomiting |
| Onset | 15 days ago, now subsided |
| Residual | Persistent imbalance/disequilibrium |
| Tandem gait | Abnormal (cannot walk heel-to-toe) |
| Romberg (classical + sharpened) | Likely positive — suggests posterior column or cerebellar dysfunction |
Most Likely Diagnosis: Cerebellar Infarction (PICA Territory)
This presentation is the textbook picture of a posterior inferior cerebellar artery (PICA) territory infarct or less likely an SCA territory infarct.
Why NOT peripheral (vestibular neuritis)?
The key differentiating features — per the Table of Central vs Peripheral Vertigo (Cummings Otolaryngology):
| Feature | This Patient | Central (Cerebellar) | Peripheral |
|---|---|---|---|
| Imbalance severity | Severe, persisting | Severe | Mild–moderate |
| Recovery | Slow, 15 days+ | Slow | Rapid |
| Neurologic signs | Tandem gait ✗, Romberg ✗ | Frequent | Rare |
| Nausea/vomiting | Present (acute phase) | Variable | Severe |
Vestibular neuritis typically resolves within days and does not produce lasting tandem gait failure or positive Romberg.
Anatomy of the Infarct
PICA territory cerebellar infarction (most common symptomatic cerebellar infarct):
- Medial PICA → acute vertigo + truncal ataxia ← this patient's picture
- Lateral PICA → unsteadiness, limb dysmetria without vertigo
- Bilateral PICA → gait ataxia, bilateral nystagmus
"PICA or medial PICA territory infarctions cause acute onset vertigo and truncal ataxia... Patients may also present with isolated vertigo resembling acute vestibular neuritis." — Localization in Clinical Neurology, 8e
"Cerebellar infarction or hemorrhage arises with severe vertigo, vomiting, and ataxia without associated brain stem symptoms — the key differential is the finding of clear cerebellar signs, direction-changing gaze-evoked nystagmus, and a normal head-thrust test." — Goldman-Cecil Medicine
Romberg Interpretation in Context
From Harrison's Principles (2025):
| Sign | Cerebellar Ataxia | Sensory Ataxia |
|---|---|---|
| Romberg | +/− (may be positive but not classic Romberg) | Strongly positive (falls on eye closure) |
| Tandem gait | Abnormal — unable to walk heel to toe | Abnormal |
| Heel-shin | Abnormal | +/− |
| Base | Wide-based, lurching | Wide-based, looks down |
Key distinction: A strongly positive Romberg (worse with eyes closed) suggests dorsal column/sensory ataxia. In cerebellar lesions, patients are ataxic with eyes open AND closed — the sharpened Romberg (feet together, arms crossed) may be positive due to coordination failure rather than proprioceptive loss.
If Romberg is strikingly positive (normal with eyes open, falls with eyes closed), consider also ruling out:
- Posterior column disease (vitamin B12 deficiency, tabes dorsalis)
- Bilateral vestibulopathy
Differential Diagnosis
| Diagnosis | For | Against |
|---|---|---|
| Cerebellar infarction (PICA/SCA) | Age, vascular risk, severe/prolonged vertigo, tandem gait failure, slow recovery | No brainstem signs mentioned |
| Vestibular neuritis | Acute severe vertigo + vomiting | No recovery at 15 days; tandem gait failure unusual |
| Vertebrobasilar insufficiency/TIA | Age, vascular | TIAs are brief minutes; this lasted 4–5 hours |
| Cerebellar hemorrhage | Same as infarction | Usually more severe, headache prominent |
| BPPV | Very common | Duration 4–5 hours is too long; no positional trigger described |
| Labyrinthitis | Acute vertigo + vomiting | Persistent ataxia/gait failure suggests central |
Bedside Examination — HINTS Battery (Critical)
The HINTS exam (Head Impulse, Nystagmus, Test of Skew) should be performed if nystagmus is still present:
| Component | Central Finding | Peripheral Finding |
|---|---|---|
| Head Impulse Test | Normal (no corrective saccade) | Abnormal (corrective saccade present) |
| Nystagmus | Direction-changing on gaze / vertical/torsional | Unidirectional, decreases with fixation |
| Test of Skew | Skew deviation present | Absent |
A normal HIT + direction-changing nystagmus + skew deviation = 100% sensitivity, 90% specificity for stroke — Cummings Otolaryngology, 8e (PMID 108 cited therein)
Investigations
Priority:
- MRI brain with DWI — Gold standard (CT misses posterior fossa infarcts; early DWI may also be falsely negative in first 24–48h but at 15 days, it will show the lesion)
- MRA Circle of Willis / posterior circulation — Vertebral artery dissection, basilar stenosis
- Fasting glucose, lipids, HbA1c, BP — Vascular risk factors
- ECG + Holter — Cardioembolic source (AF)
- Echocardiogram — Intracardiac thrombus/PFO
- CBC, coagulation — If dissection suspected
Also consider:
- Audiometry (AICA territory infarcts involve internal auditory artery → unilateral hearing loss + tinnitus)
- Serum B12, VDRL if Romberg strongly positive eyes-closed
Management
Acute cerebellar infarction:
- Antiplatelet therapy (aspirin ± clopidogrel — dual antiplatelet for 21 days in non-cardioembolic stroke per current guidelines)
- If AF confirmed → anticoagulation (DOACs preferred)
- Statin therapy (atorvastatin 40–80mg)
- BP control (target <130/80 for secondary prevention)
- Vestibular rehabilitation — physiotherapy-guided balance exercises to accelerate central compensation
- Suppress acute nausea with prochlorperazine or ondansetron (short-term only; antihistamines/antiemetics can delay central compensation if used long-term)
- Monitor for cerebellar swelling (especially in large PICA infarcts) — neurosurgical decompression if progressive obtundation
Rehabilitation:
- Vestibular physiotherapy (Cawthorne-Cooksey exercises, balance training)
- Tandem gait and Romberg deficits typically improve over weeks to months with cerebellar plasticity
Summary
This 58-year-old male almost certainly had a cerebellar infarction (most likely PICA territory). The 4–5 hour duration, acute severe vertigo with vomiting, persistent imbalance, impaired tandem gait, and positive Romberg 15 days later are all hallmarks of a central posterior fossa event. MRI brain with DWI + MRA are the urgent next steps. The HINTS examination at bedside can strongly support the central diagnosis before imaging.

I now have all the pieces needed to synthesize a precise diagnostic interpretation. Let me compile the complete analysis.
Vestibular Screening Analysis — Sign-by-Sign Interpretation
Recap of All Findings (Both Sessions)
| Test | Finding |
|---|---|
| Fukuda (Unterberger) Stepping Test | Rotates >45° to the LEFT |
| Tandem gait | Abnormal |
| Romberg (classical + sharpened) | Positive |
| Head Impulse Test (HIT) | Direction-changing corrective saccades (not a clean unilateral catch-up) |
| Gaze-Evoked Nystagmus | Present — direction changes with gaze direction |
| Skew Deviation | Present |
| Finger-to-Nose | Undershooting (hypometria) |
| Positional tests (Hallpike, Supine Roll) | Normal |
Diagnosis: Central Vestibular Syndrome — Cerebellar/Posterior Fossa Lesion (LEFT SIDE)
This is unequivocally a central vestibular picture, not peripheral. Here is the sign-by-sign reasoning:
1. Fukuda Stepping Test — Rotation >45° LEFT
The Fukuda test reflects unilateral labyrinthine asymmetry. The patient deviates toward the hypofunctional (weaker) side.
"The patient turning clockwise/counterclockwise during the test is considered positive for peripheral vestibular weakness... most sensitive for severe or profound unilateral labyrinthine dysfunction." — Cummings Otolaryngology, 8e
Turning left >45° indicates weakness/suppression of the LEFT vestibular system (or cerebellar pathways on the LEFT). However, this test alone does not distinguish peripheral from central — it just localizes the side.
Key point: In a cerebellar infarction (PICA territory), the cerebellar modulation of the VOR is lost ipsilaterally, producing an apparent "peripheral-like" deviation toward the lesioned side on Fukuda.
2. Head Impulse Test (HIT) — Direction-Changing / No Clean Corrective Saccade
This is the most critical finding for central localization.
In peripheral vestibular disease (vestibular neuritis):
- HIT shows a unilateral catch-up saccade (toward the lesioned side) = POSITIVE
In central disease (cerebellar stroke):
- HIT is normal (no catch-up saccade) OR shows direction-changing saccades = NEGATIVE/abnormal in a way inconsistent with peripheral
"If the horizontal head impulse test was normal (i.e., no catch-up saccade), there was skew deviation, or direction-changing nystagmus → 100% sensitivity and 90% specificity for stroke." — Cummings Otolaryngology, 8e (HINTS studies)
"A negative head-thrust test (no corrective saccade) or skew deviation could be the key indicators of a central rather than a peripheral vestibular lesion." — Bradley & Daroff's Neurology
Direction-changing corrective saccades on HIT = CENTRAL SIGN.
3. Gaze-Evoked Nystagmus — Direction-Changing
This is pathognomonic of central/cerebellar dysfunction.
"Direction-changing gaze-evoked nystagmus: patient looks to the LEFT and has left-beating nystagmus; looks to the RIGHT and has right-beating nystagmus... characteristic of brainstem or cerebellar strokes." — Bradley & Daroff's Neurology
"Horizontal nystagmus that changes direction with gaze (gaze-evoked nystagmus) is characteristic of lesions of the cerebellar pathways." — Harrison's Principles, 22e
In peripheral disease, nystagmus is unidirectional and follows Alexander's Law (increases when looking toward fast phase). Direction-changing nystagmus = CENTRAL.
The mechanism: failure of the neural integrator (flocculus/nodulus of cerebellum + nucleus prepositus hypoglossi) to hold eccentric gaze → eyes drift back to midline → corrective fast phase in the direction of gaze.
4. Skew Deviation — Present
Skew deviation (vertical misalignment of the eyes) = disruption of central otolithic pathways.
"Skew deviation and the ocular tilt reaction occur with vestibular nuclei and medullary lesions... The full ocular tilt reaction is not often observed with peripheral vestibular lesions." — Cummings Otolaryngology
"Lateral medullary lesions damage the otolithic vestibular nuclei; patients with Wallenberg syndrome often demonstrate skew deviation with hypotropia on the side of the lesion." — Localization in Clinical Neurology, 8e
Skew deviation with a positive HINTS profile (normal or direction-changing HIT + direction-changing nystagmus + skew) = stroke until proven otherwise.
5. Finger-to-Nose — Undershooting (Hypometria)
Dysmetria (under/overshooting on finger-to-nose) = cerebellar sign.
"Additional cerebellar function tests can be useful adjuncts — finger to nose, rapid hand alternation, and heel-to-shin testing may detect cerebellar dysfunction which can affect balance." — Cummings Otolaryngology
"Overshooting or undershooting of voluntary movements (dysmetria)... are all cerebellar signs." — Adams & Victor's Neurology
Undershooting specifically = hypometria, seen with cerebellar hemisphere lesions. This confirms the lesion is ipsilateral cerebellar hemisphere (LEFT), since finger-to-nose dysmetria is ipsilateral to the lesion.
6. Positional Tests (Dix-Hallpike, Supine Roll) — NORMAL
This is highly important. Normal positional tests EXCLUDE BPPV as a cause. This further confirms:
- No canalolithiasis
- No cupulolithiasis
- The canal organs are not the primary pathology
HINTS Summary in This Patient
| HINTS Component | Finding | Interpretation |
|---|---|---|
| H — Head Impulse Test | Direction-changing / no clean unilateral saccade | CENTRAL |
| I — Nystagmus | Direction-changing, gaze-evoked | CENTRAL |
| N — No skew | Skew deviation PRESENT | CENTRAL |
All three HINTS components point CENTRAL → Stroke until proven otherwise.
Final Diagnosis
Left Cerebellar Infarction (likely PICA or SCA territory, LEFT side)
Localizing signs pointing LEFT:
- Fukuda deviation LEFT → left cerebellar/vestibular hypofunction
- Finger-to-nose undershooting (hypometria) — ipsilateral to the cerebellar lesion
Central (not peripheral) confirmed by:
- Direction-changing gaze-evoked nystagmus
- Direction-changing/absent corrective saccade on HIT
- Skew deviation
- Finger-to-nose dysmetria (absent in peripheral vertigo)
- No BPPV on positional testing
- Persistent imbalance >15 days (peripheral vestibular neuritis recovers faster)
Immediate Action Plan
- MRI brain with DWI + FLAIR (urgently — confirms infarct; at 15 days, lesion will be clearly visible)
- MRA posterior circulation — assess vertebral artery, PICA, basilar
- Cardiology workup — ECG, Holter, Echo (embolic source)
- Vascular risk factor control — BP, HbA1c, lipids
- Antiplatelet + statin (if ischemic stroke confirmed)
- Vestibular rehabilitation referral — balance physiotherapy
Why Peripheral Is EXCLUDED
| Feature | This Patient | Peripheral (Neuritis) |
|---|---|---|
| HIT | Direction-changing saccade | Unilateral catch-up saccade |
| Nystagmus | Direction-changing | Unidirectional |
| Skew | Present | Absent |
| Finger-to-nose | Dysmetric | Normal |
| Positional tests | Normal | May be abnormal |
| Duration of imbalance | 15 days, persistent | Usually resolving |
The clinical picture is a central vestibular syndrome localized to the left cerebellar hemisphere, consistent with left PICA territory cerebellar infarction.

Can u write the one paragraph summary of clinical history no need of results only history
A 58-year-old male presented with a chief complaint of sudden onset severe vertigo (chakkar) occurring 15 days prior to evaluation, which lasted approximately 4–5 hours and was accompanied by nausea and vomiting. Following resolution of the acute vertiginous episode, the patient continued to experience persistent imbalance and disequilibrium. On clinical vestibular screening, tandem gait was found to be impaired, both classical and sharpened Romberg tests were positive, the Fukuda stepping test showed a rotation greater than 45 degrees toward the left side, skew deviation was noted on ocular examination, gaze-evoked nystagmus was present with direction-changing characteristics, the head impulse test revealed direction-changing corrective saccades rather than a clean unilateral catch-up saccade, and finger-to-nose testing demonstrated undershooting (hypometria) consistent with ipsilateral cerebellar dysfunction. Positional tests including the Dix-Hallpike and supine roll test were negative bilaterally, excluding a benign paroxysmal positional etiology.
