Thyrotropin-secreting pituitary adenomas (TSHomas) represent a rare subtype of pituitary tumors. Neurosurgery (NCH) is still considered the first-line therapy. In this study we aimed to investigate the outcome of different treatment modalities, including first line somatostatin analogs (SSA) treatment, with a specific focus on neurosurgery-related complications.

We retrospectively evaluated thirteen patients diagnosed for TSHomas (9 M; age range 27–61). Ten patients had a magnetic resonance evidence of macroadenoma, three with slight visual field impairment. In the majority of patients, thyroid ultrasonography showed the presence of goiter and/or increased gland vascularization. Median TSH value at diagnosis was 3.29 mU/L (normal ranges 0.2–4.2 mIU/L), with median fT4 2.52 ng/dL (0.9–1.7 ng/dL).
