Simultaneous occurrence of transient resolving thyrotoxicosis due to painless thyroiditis, hypopituitarism and diabetes insipidus following pituitary apoplexy.

Pituitary apoplexy is characterized by a wide spectrum of clinical features, not only in mode of presentation but also in outcome.'-3 We treated a patient with a previously undiagnosed pituitary tumour in whom spontaneous pituitary apoplexy occurred. Subsequently, impairments of both anterior and posterior pituitary function and transient resolving thyrotoxicosis secondary to painless (silent) thyroiditis4'5 developed. To our knowledge, these events concomitant with pituitary apoplexy have not been previously reported.
