LEóN BLASCO, Ana; GALINDO PORTUONDO, Eduardo  e  RIVACOBA MARTINEZ, Adriana. Pituitary Adenoma as a Rare Form of Secondary Adrenal Insufficiency. A Case Report. Medisur [online]. 2014, vol.12, n.1, pp. 118-124. ISSN 1727-897X.

Pituitary adenomas are benign tumors arising from one of the five cell types in the anterior pituitary. Secondary adrenal insufficiency occurs when the adrenal glands do not produce hormones due to the lack of pituary adrenocorticotropic hormone or hypothalamic corticotropin-releasing factor. The case of a 37-year-old female patient who started developing muscle twitching in legs and arms, muscular weakness, fatigue, muscle aches, severe and throbbing hemicrania on the right side, among other symptoms, a year ago is presented. Several tests were performed (cortisol level, adrenocorticotropic hormone, calcium and phosphorus in blood and urine, magnetic resonance imaging of the skull), leading to the diagnosis of pituitary adenoma with isolated adrenocorticotropic hormone deficiency and secondary adrenal insufficiency. Treatment with steroids and calcium supplements ensured a satisfactory recovery.
