Cushing's syndrome is a rare disease caused due to prolonged exposure to excess glucocorticoids. Although rare, diagnosing Cushing's syndrome is clinically significant as it allows tailored and timely management and significant reduction or even prevention of the comorbidities caused by cortisol excess. This report delineates the presentation of a 44-year-old female with refractory secondary hypertension and severe hypokalaemia, initially thought to be caused by hyperaldosteronism.

Corticotropin-releasing hormone (CRH) signaling through its cognate receptors, CRHR1 and CRHR2, contributes to diverse stress-related functions in the mammalian brain. Whereas CRHR2 is predominantly expressed in choroid plexus and blood vessels, CRHR1 is abundantly expressed in neurons in discrete brain regions, including the neocortex, hippocampus and nucleus accumbens. Activation of CRHR1 influences motivated behaviors, emotional states, and learning and memory.

Introduction: Vigabatrin, an anticonvulsant drug used for refractory epilepsy and as first-line treatment for infantile epileptic spasms syndrome, can rarely cause brain abnormalities detectable on magnetic resonance imaging.

Upon withdrawal or dose reduction, symptoms and imaging changes tend to resolve.
