A Rare Association of Hypomagnesemia and Posterior Reversible Encephalopathy Syndrome (PRES)

Posterior reversible encephalopathy syndrome (PRES) is a rare neurologic disorder that presents with variable symptoms and symmetrical abnormal white matter signaling most commonly of the occipital parietal lobes on magnetic resonance imaging (MRI). PRES, also known as posterior leukoencephalopathy (RPLS) associated hypertension. Hypomagnesemia’s association PRES has been rarely reported. Here, we report patient severe hypomagnesemia presented improved magnesium replacement. Hypomagnesemia should be considered an underlying etiology in patients presenting promptly treated. The presentation can often concerning for acute cerebrovascular accidents dysarthria upper motor neuron symptoms, such facial droop, dysarthria, gait instability. Differential diagnosis includes rostral brainstem infarction, transient ischemic attack, infectious encephalopathy, metabolic/toxic which evaluated description case. common RPLS/PRES altered mental status, drowsiness, seizure, vomiting, alterations speech including visual disturbance. first signs noted are lethargy somnolence. In this case, notably initial serum corrected rapidly administration intravenous sulfate.
