RÉSUMÉ
The evaluation of new seizures is a common clinical query for neurologists. It can be challenging to delineate between the numerous etiologies of new focal or generalized seizures and, if focal, to localize their onset. In this case report, we present a 26-year-old patient with a new onset of stereotyped events concerning for seizures featuring facial grimacing, dystonic left-hand posturing, and convulsions with immediate return to baseline. Throughout the case, we highlight a stepwise diagnostic approach to the evaluation of new-onset seizures, discuss clues that seizure semiology can provide for localization of ictal onset, and review a novel and atypical presentation of a disease entity frequently encountered by neurologists.

Myelopathy can present acutely or more insidiously and has a broad differential diagnosis. In addition to the clinical history and neurologic examination, diagnostic testing, including MRI and cerebrospinal fluid analysis, as well as thorough review of patient comorbidities, risk factors, and potential toxic exposures, can help neurohospitalists distinguish between various causes and potentially start appropriate empiric therapy while awaiting definitive testing. This article focuses on how imaging can help in determining the most likely cause of myelopathy and highlights a range of causes, including compressive, vascular, metabolic and toxic, infectious, autoimmune, neoplastic, and paraneoplastic causes of spinal cord dysfunction.
