Uncontrolled hypertension led to recurrent posterior reversible encephalopathy syndrome (PRES) that was initially misdiagnosed as osmotic demyelination syndrome due to overlapping radiologic features.
Case Report (n=1)
Highlights the diagnostic challenge of distinguishing PRES from ODS in patients with uncontrolled hypertension and hyponatremia.
We report a case of recurrent posterior reversible encephalopathy syndrome (PRES) secondary to uncontrolled hypertension, initially misdiagnosed as osmotic demyelination syndrome (ODS) due to concomitant hyponatremia and overlapping radiologic features. PRES is a neurotoxic state characterized by vasogenic edema predominantly affecting the parieto-occipital regions, but in some cases, it may extend to deep gray matter and the brainstem, leading to diagnostic confusion with ODS.
Shin et al. (Tue,) conducted a case report in Recurrent posterior reversible encephalopathy syndrome (PRES) (n=1). Uncontrolled hypertension was evaluated. Uncontrolled hypertension led to recurrent posterior reversible encephalopathy syndrome (PRES) that was initially misdiagnosed as osmotic demyelination syndrome due to overlapping radiologic features.
