摘要
A 42-year-old man presents with decreased libido, erectile dysfunction, and headaches. He reports no weight change, gynecomastia, fatigue, or other symptoms. He takes no medications. Testicular size is decreased on examination. His prolactin level is 648 mu g per liter (normal value, <15). Magnetic resonance imaging (MRI) reveals a sellar mass (2.5 by 1.5 by 2.0 cm) that is 5 mm below the optic chiasm and that extends bilaterally into the cavernous sinuses. What are the diagnostic and therapeutic considerations?
