Background: Several cases of autoimmune disease onset after treatment for Cushing's syndrome have been reported.
Case presentation: Herein, we report a case of myasthenia gravis crisis in a 51-year-old woman 2 months after adrenalectomy for adrenal Cushing's syndrome accompanied by takotsubo cardiomyopathy. The resolution of excessive endogenous cortisol after adrenalectomy may have triggered the onset of previously latent myasthenia gravis.
Conclusions: Observing the similarities in symptoms between myasthenia gravis and adrenal crisis, which can sometimes be challenging to differentiate, is essential. Moreover, the presence of takotsubo cardiomyopathy as a non-motor manifestation of myasthenic crisis must be noted.
