title: CyberKnife radiosurgery planning of a secreting pituitary adenoma performed with ⁶⁸Ga DOTATATE PET and MRI.
abstract: The images of a patient with acromegaly, who previously underwent operation for pituitary adenoma, were obtained. The MRI scan showed a mass in the right cavernous sinus, with biochemical test results positive for the presence of a hormonally active adenoma. The patient was scheduled for CyberKnife radiotherapy. Radiotherapy planning was carried out using MRI and PET/CT scan with somatostatin analog ⁶⁸Ga DOTATATE. The latter showed radiopharmaceutical uptake on the adenomatous residual mass. Contours were drawn on MRI and PET images and were summed up to devise the radiotherapy plan. The patient was treated with a total dose of 24 Gy.
