ABSTRACT: Background: Brain metastases from papillary thyroid carcinoma are infrequent occurring in 0.15% to 1.3% of patients, and they are generally accompanied by synchronous metastases in other sites and in isolation are even less frequent; the information about their management is limited and it has been based mainly on retrospective studies, experiences, case reports, and management guidelines of brain metastasis of other cancers. Aim: We report this case with the objective of describing how unpredictable the behavior of thyroid cancer can be despite being classified as low risk of recurrence. Case Presentation: A female patient with a diagnosis of papillary thyroid carcinoma classified as low risk who after more than a year of surveillance and without alterations in laboratory and imaging studies, developed a single brain metastasis susceptible to treatment with radioactive iodine (RAI) therapy. Conclusion: This case emphasizes the importance of a close follow-up of patients and not to minimize any symptom, no matter how simple it may seem, since cancer has no rules in its evolution.
