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.
