A case of Dyke-Davidoff-Masson syndrome associated with central hypothyroidism and secondary adrenal insufficiency.

A diagnosis of central hypothyroidism (CH) can be missed easily or delayed without a high index of suspicion due to normal or slightly altered thyroid stimulating hormone (TSH) levels during the initial screening test for thyroid dysfunction. A correct diagnosis of CH is very important for safely treating patients. Specifically, doctors must ensure a proper evaluation of combined adrenal insufficiency to prevent a fatal adrenal crisis. Here we report a case of CH combined with secondary adrenal insufficiency in a 42-year-old woman with Dyke-Davidoff-Masson syndrome, which is a rare neurological disease.
