Misdiagnosis of CADASIL: A single Medical Center experience (P1.251)
Conclusions:CADASIL is the most prevalent monogenic cerebral small-vessel arteriopathy. Despite wide availability of genetic testing, misdiagnosis and delay diagnosis are common. We encourage for enhanced awareness of CADASIL among patients with migraines with aura, recurrent TIAs or subcortical ischemic strokes, and mood disorder, in order to provide appropriate multidisciplinary treatment, psychological support and genetic counselingStudy Supported by: n/aDisclosure: Dr. Ortiz-Garcia has nothing to disclose.

Common etiologies of acute symptomatic seizures evolving from lateralized periodic discharges in patients monitored with continuous EEG (P2.233)
Conclusions:The most common high risk etiologies of acute symptomatic seizures evolving from lateralized periodic discharges in our cohort of patients were ischemic stroke, tumor, encephalitis, and subdural hematoma. Recognition of these etiologic factors may influence the duration of continuous EEG monitoring employed or the decision to institute seizure prophylaxis. A larger cohort of patients should be reviewed in a future study to confirm these findings.Disclosure: Dr. Mathew has nothing to disclose. Dr. Piran has nothing to disclose.

Sporadic Creutzfeldt-Jakob Disease Presenting as Non-Convulsive Status Epilepticus: A Case Report (P1.333)
CONCLUSIONS: Non-convulsive status epilepticus is an extremely rare presentation of prion disease. To date, there have only been three reported cases in the literature. This case highlights the need to consider prion disease as an etiology in NCSE and NORSE.Disclosure: Dr. Alobaidy has nothing to disclose. Dr. Parker has nothing to disclose.

4 Cases of Aseptic Encephalitis Mimicking Right Middle Cerebral Artery Syndrome (P6.028)
We present 4 cases of presumed aseptic encephalitis in Southern California all causing a transient right MCA syndrome (eyes deviated to the right, left hemianopia, left hemiparesis, and inattention), with 3 of them presenting within a 10 day period, and all within a geographic radius of 40 miles. None of these cases had right MCA vascular occlusions, ischemic infarcts on imaging or severe hyperglycemia. All patients had near-complete resolution of the right MCA syndromes between 3-12 days. 2 of 4 cases developed complex or secondary generalized partial motor seizures requiring treatment with antiepileptic drugs. Every pati...

HSV-2 Encephalitis Presenting as Multifocal Ischemic Stroke (P4.375)
CONCLUSION A high index of suspicion needs to be maintained to diagnose infectious vasculitis. A history of immunosuppression and headache preceding cerebral infarction were important factors that ultimately led to the appropriate work up and diagnosis in this case. Lumbar puncture and prompt initiation of antiviral treatment is essential in stroke case of suspected CNS infection with HSV-2.Disclosure: Dr. Zhang has nothing to disclose.

Acute Diffusion-Weighted MRI Abnormalities in Status Epilepticus (P4.190)
Conclusions: Our findings revealed that the abnormality on diffusion-weighted MRI and residual brain atrophy in status epilepticus is more frequent than previous study. These abnormalities may reflect the epileptogenic hyperexcitation and propagation of ictal discharge.Disclosure: Dr. Son has nothing to disclose.

Predictors of Poor Outcome in Neuroleptic Malignant Syndrome: Retrospective Analysis of Nationwide Inpatient Sample (S32.006)
CONCLUSIONS: In patients admitted for neuroleptic malignant syndrome, every decade increment in age, acute kidney injury, seizures and respiratory failure were positive predictors of poor outcome. Every calendar year increase was a negative predictor of poor outcome. Study Supported by:Disclosure: Dr. Modi has nothing to disclose. Dr. Dharaiya has nothing to disclose.

Limbic Encephalitis Exacerbations and Remissions Charted by Microglial PET Scan: A Case Study (P4.104)
CONCLUSIONS: C-11-PK11195 PET imaging can be useful in the diagnosis of limbic encephalitis and for monitoring response to treatment. MALT lymphoma may also be associated with autoimmune or paraneoplastic encephalitis, especially in individuals with other predisposing factors to autoimmune disorders, such as Tourette’s and autoimmune thyroid disease. The reduction in microglial activity with both IVIG and anti-psychotics supports previous findings that anti-psychotics may act through anti-inflammatory pathways.Disclosure: Dr. Shatz has received research support from Janssen Pharmaceutica.

Mitochondrial Encephalopathy with Lactic Acidosis and Stroke (MELAS) presenting as an apparent neoplastic process (P5.015)
CONCLUSION: MELAS can mimic more common disorders. The slow onset of her symptoms and the MRI's appearance led to suspicion for neoplasm. This is the first report to our knowledge where MELAS has presented as such. Documentation of this and other unusual presentations of mitochondrial disease is crucial to appropriate diagnosis of the condition.Disclosure: Dr. Rothstein has nothing to disclose.

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.

Cerebral myiasis
An 85-year-old patient was admitted to the emergency room septic with fetid odor in the right orbit, where enucleation of the right eye had been performed 8 years prior. Physical inspection noted the presence of larvae within the right orbit. After a CT scan (figure 1), the patient underwent surgical treatment (figure 2). Intraoperative cultures revealed encephalitis caused by myiasis. The patient died due to complications caused by sepsis 2 weeks after the procedure.
