Pituitary Microadenoma Presenting with Panhypopituitarism and Hyponatremia: A Case Report

Ravi Kant, Elizabeth Zipprer, Riddick Blocker, Mark Cromer, Rashmi Chandra, Vipin Verma

The prevalence of pituitary adenomas is rising as more are incidentally reported on Magnetic Resonance Imaging (MRI) and Computerized Tomography (CT) imaging studies. While most exist without causing clinical symptoms or laboratory abnormalities, a non-functional sellar mass can initially present with panhypopituitarism. We present a case of pituitary microadenoma that presented with severe hyponatremia and panhypopituitarism. This patient had a non-functional pituitary microadenoma and was hospitalized many times for hyponatremia before finally being diagnosed with panhypopituitarism.
