SESSION TITLE COVID-19 Case Report Posters 3 SESSION TYPE Case Report Posters PRESENTED ON 10/19/2022 1245 pm - 0145 pm INTRODUCTION: We are presenting a rare case of Posterior Reversible Encephalopathy Syndrome (PRES) without traditional risk factors in a patient with Covid 19. CASE PRESENTATION Patient is a 41 y/o F with a past medical history of obesity, seizure disorder, epilepsy, hyperlipidemia and asthma who was admitted for Covid 19 pneumonia. Patient was transferred to the ICU on day #5 and intubated on day #8. Patient was given remdesivir, dexamethasone and baricitinib. Patient required intermittent vasopressors as her blood pressure varied between hypotensive and normotensive. Rarely her blood pressure increased to a hypertensive range. Patient had a thrombotic event on day #19 in her right upper extremity secondary to continuous renal replacement to manage acute renal failure. On Day #24, patient became unresponsive without sedation with an EEG showing moderate to severe slowing. On day #26 patient had a decreased response to stimuli leading to an MRI to evaluate for Posterior Reversible Encephalopathy Syndrome (PRES). MRI highlighted abnormal signal in the brain parenchyma concentrated mainly in the posterior brain consistent with PRES. On day #31 patient exhibited seizure like diffuse tremor. Blood pressure ranged from 90/72 to 137/84 hospital days #20-31. Status epilepticus was evaluated by an long term monitoring EEG showed diffuse slowing and occasional sharp wave activity in the right posterior cerebellum and occipital region without active seizures. On day #39 patient was found to have an acute hemorrhagic stroke of the left temporal region which resolved on day #43. On day #47 patient was transferred to a tertiary care center for tracheostomy placement and discharged on day #55 to a LTACH for rehab. DISCUSSION: PRES is a rare but severe complication of Covid 19 infection. Previous cases showed variability in underlying causes. Our patient showed significant endothelial dysfunction leading to multiple thrombotic events[1]. While our patient had rare hypertensive episodes, they were not persistent nor severe, nor were they present at the time of her seizure activity[1][2]. In comparison to previous cases, our patient had overlapping risk factors such as renal failure, obesity and dyslipidemia[1]. Our patient showed common clinical manifestations of PRES such as seizures, focal neurological deficits, and altered mental status with previous cases[1]. Our patient was not given tocilizumab in contrast with previous cases, however was given corticosteroids[1][2]. CONCLUSIONS: The above is a rare case of PRES without traditional risk factors. Providers must keep a wide differential diagnosis in patients with Covid 19. Reference #1 Lallana, S., Siegler, J. E., Chen, A., Requena, M., Rubiera, M., & Sanchez, A. (2021).
