A Rare Case of Pituitary Carcinoma With Bone Metastases: 68Ga-DOTATATE PET/CT Findings

Pituitary carcinomas are extremely rare and aggressive tumors that comprise only 0.2% of all pituitary tumors. Because of its rarity, pituitary carcinomas are difficult to diagnose. Conventional imaging methods are inadequate to detect metastatic lesions. Pituitary carcinomas are neuroendocrine tumors and express somatostatin receptors; therefore, Ga-68-DOTATATE PET/CT may be used in the staging of these rare tumors. Herein, we present an exceptional case of pituitary carcinoma with sclerotic skeletal metastases showing Ga-68-DOTATATE uptake.

Pituitary carcinomas are rare and aggressive tumors that are difficult to diagnose. Conventional imaging methods are inadequate for detecting metastatic lesions. Ga-68-DOTATATE PET/CT may be useful in the staging of these rare tumors.
