CORREA, Carlos et al. Hyponatremia associated with hypopituitarism in empty sella syndrome. Rev. virtual Soc. Parag. Med. Int. [online]. 2020, vol.7, n.1, pp.134-140. ISSN 2312-3893.

A 53-year-old female patient was admitted by a clinical case of 10 days of evolution characterized by myalgia and edema in the lower extremities. On physical examination: facial swelling, dry skin, fine hair, decreased axillary and pubic hair. In the laboratory there is evidence of elevation of muscle enzymes (myoglobin 3000 U/L, CPK 2876 U/L), alteration of serum Na 112 mEq/L, altered thyroid profile (normal to low TSH 1.14 IU/mL and FT4 low 0.08 IU/ml), AM cortisol 7.2 mcg/dL. Magnetic resonance imaging is requested with sella Turcica protocol. It is observed a decreased pituitary gland in all its diameters confirming the finding of a partially empty sella syndrome. Hyponatremia associated with hypopituitarism is uncommon.
