Inferior Cerebellar Peduncular Lesion Causes a Distinct Vestibular Syndrome (P1.332)
CONCLUSIONS: Unilateral ICP lesion at the pontine level mimics acute peripheral vestibular disorders. However, directional dissociation between OTR/SVV tilt and body lateropulsion with normal head impulse or caloric tests may be a sign distinguishing lesions involving unilateral ICP at the pontine level from those affecting other vestibular structures.

Primary Angiitis of the Central Nervous System (PACNS) presenting with intracerebral hemorrhage (ICH): three cases associated with chronic use of over-the-counter vasoconstrictive drugs (P7.128)
CONCLUSIONS: While the FDA withdrew phenylpropanolamine due to its association with ICH, other vasoconstrictive agents remain ingredients of nasal decongestants/diet pills. These may induce chronic vasoconstriction leading to secondary inflammation and arterial rupture, culminating in atypical PACNS presentations such as multifocal ICH or ICH with acute infarcts (patients 1,2).Disclosure: Dr. Jha has nothing to disclose. Dr. George has nothing to disclose. Dr. Singhal has received personal compensation for activities as a medicolegal expert witness. Dr. Singhal's spouse holds stock and/or stock options in Biogen Idec.

Why acute unilateral vestibular cortex lesions mostly manifest without vertigo
Conclusion: Thus, rare vestibular cortical vertigo is mostly elicited by acute lesions of the core region of the retroinsular vestibular network. However, the more interesting question is related to the lack of cortical vertigo when this area is affected. We propose a concept to explain how the unaffected opposite hemisphere can suppress vertigo. This is based on visual–vestibular interaction for motion perception and orientation. It is the hemisphere in which vestibular and visual inputs are in agreement, which is the more reliable and determines the global perception of body orientation and motion.

An Unusual Stroke-like Clinical Presentation of Creutzfeldt-Jakob Disease: Acute Vestibular Syndrome
Conclusions: To our knowledge, this is the first report of an initial presentation of Creutzfeldt-Jacob disease closely mimicking vestibular neuritis, expanding the known clinical spectrum of prion disease presentations. Despite the initial absence of neurological signs, the central lesion location was differentiated from a benign peripheral vestibulopathy at the first visit using simple bedside vestibular tests. Familiarity with these tests could help providers prevent initial misdiagnosis of important central disorders in patients presenting vertigo or dizziness.

Intracranial Hemorrhage and Deep T Wave Inversions
A woman in her 70s with a medical history significant for atrial fibrillation and cardioembolic stroke who was receiving long-term anticoagulation therapy with warfarin (international normalized ratio, 2.3) presented to an outside facility with sudden onset of nausea and vertigo. Her mental status declined and she was unable to protect her airway, prompting intubation. Computed tomographic scan (CT) at that time was negative for any intracranial pathologic findings. On arrival to our facility, the patient remained lethargic and unresponsive; therefore, a second noncontrast head CT was performed, which showed no evidence fo...

Impact of initial symptom for accurate diagnosis of vertebral artery dissection
ConclusionsIn our study, headache and/or neck pain, especially unilateral presentation, and vertigo were symptoms associated with the stratification of Spontaneous Cervicocephalic Arterial Dissections Study criteria. Physicians should carefully obtain clinical history for the presence of a unilateral headache and/or neck pain and vertigo when vertebral artery dissection is suspected in patients with or without objective neurological signs.

Teaching NeuroImages: Isolated peripheral facial palsy due to ipsilateral pontine infarction
A 72-year-old woman presented left peripheral facial palsy for 1 day. Neurologic examination revealed isolated left peripheral facial palsy (figure 1). She did not have additional pontomedullary symptoms or signs, such as diplopia, abduction weakness, facial sensory loss, vertigo, nystagmus, or dysarthria. A brain diffusion-weighted MRI scan showed a hyperintense signal in the left dorsal pons (figure 2) in the region of the seventh nerve nucleus. Infranuclear facial palsy with isolated facial weakness has been reported rarely, and may be misdiagnosed as Bell palsy.1,2

A 69-year-old woman with a "sweet" cause of instability
A 69-year-old woman presented to the emergency department with dizziness and instability. She had a history of peripheral vertigo, tinnitus, and one episode of orthostatic syncope in recent years; her only daily medication was zolpidem. Her past medical history was unremarkable.

Bullous pemphigoid and neurodegenerative diseases: a study in a setting of a Central European university dermatology department.
Abstract Bullous pemphigoid (BP) is an autoimmune blistering dermatosis of the elderly mediated by IgG and IgE antibodies to skin hemidesmosomal proteins, BP180 and/or BP230, that occur physiologically also in neuronal tissue. It was reported that BP is associated with neurodegenerative diseases (ND). We performed a retrospective study in a setting of a Central European university dermatology department on prevalence of ND in 94 BP patients. 26 out of 94 BP patients had at least one ND. ND included: Parkinson's disease, dementia, stroke, hear loss, tinnitus, blindness, vertigo, neurosyphilis, systemic sclerosis, a...

Clinical Reasoning: A 50-year-old man with "elephantiasis" and headache
A 50-year-old man with a medical history of "elephantiasis" of the legs, status post left above the knee amputation with prosthetic limb, and hypothyroidism presented with 1 week of headache and nausea. The headache was continuous, with gradual worsening over the 7 days prior to admission, and he had minimal relief with ibuprofen. On the second day, he developed nausea. He denied any history of headaches, blurred or double vision, numbness, weakness, tingling, loss of balance, vertigo, chest pain, palpitations, or shortness of breath. In the emergency room, he was afebrile with a heart rate of 78 beats per minute and regul...

Paraneoplastic Neurological Syndrome in Fallopian Tube Cancer.
We report on a rare case of paraneoplastic syndrome (PS) that was discovered on completion of diagnostic work-up to be an undifferentiated fallopian tube carcinoma. A 49-year-old Caucasian woman was admitted to neurology with vertigo, gait ataxia and dysarthria, transient ischaemic attack (TIA) and stroke were quickly excluded. Indicative for the further diagnosis of a paraneoplastic syndrome was the identification of onconeuronal antibodies the detection of which can be associated with certain tumour entities. The strongly positive anti-Yo antibody that is formed above all by breast and lung cancers as well as ovarian can...

Puerperal Extracranial Vertebral Artery Dissection and Nonaneurysmal Subarachnoid Hemorrhage
Previously reported only a few times before, we present a case of extracranial vertebral dissection and spontaneous frontoparietal subarachnoid hemorrhage (SAH) in the puerperium, discussing possible mechanisms and difficulties in management. A 35-year-old woman presented 10 days postcaesarean section with neck pain and vertigo with normal initial investigations. Following recurrent vertigo, headache, and ataxia, imaging revealed a frontoparietal SAH and vertebral artery dissection. The patient was consequently treated with aspirin, and then following a return of symptoms 3 weeks later, warfarin therapy was continued for 6 months.
