Tyroid-stimulatin hormone (TSH) - producing pituitary adenomas known as thyrotropinomas or TSHomas account for a small percentage of pituitary tumors . Approximately 30% of them co-secrete growth hormone (GH), Prolactin, or αGSU of TSH . We introduce a patient with a 12 years follow-up at our center with medical treatment by long-acting somatostatin analogues (SSA) due to rejected surgery. Along the treatment there is a scape with a secondary production of GH without image changes at the MRIs. We suggest a progressively acquired resistance to the medical treatment.
