12 Right Occipital Arteriovenous Malformation presenting as a Migraineous Visual AuraMigraine with visual aura is a distinct entity from a migraineous visual aura. A migraine with visual aura is characterized by a visual aura that does not prefer either visual field and accompanies a headache. The mechanism of the visual aura is via cortical spreading depression. A migraineous visua...Nithya Shanmugam; Fernando Labella; Valerie Biousse
13 Second Order Horner Syndrome Revealing Metastatic Squamous Cell CarcinomaHorner Syndrome is secondary to a lesion of the ipsilateral sympathetic pathway and is associated with ptosis, miosis, and anhidrosis. Here, we present a unique presentation of metastatic squamous cell carcinoma in a patient with a right-sided Horner Syndrome (second order). We also highlight the di...Nithya Shanmugam; Michael Dattilo; Valerie Biousse
