Conclusion and Results (Outcome and follow-up):
At her one-year follow-up, the patient was completely asymptomatic. Her
menstrual cycle had remained regular, her weight was stable, she had no
headaches, and she was compliant with her levothyroxine regimen. Her lab
parameters continued to be within normal ranges (Table 3).
Initially, a pituitary adenoma was suspected based on misleading MRI
findings. This case highlights the importance of thoroughly assessing
lab parameters before relying on imaging alone, as her blood test
results ultimately prevented unnecessary surgical intervention.
