68ga-dotanoc and Paraneoplastic-Syndromes

Tumor-induced osteomalacia is a rare paraneoplastic syndrome, usually caused by small benign mesenchymal tumors. The tumors most arise within the extremities, whereas occurrence within the parotid gland is quite rare. A 54-year-old woman who presented with bone pain and muscle weakness for 2 years was clinically suspected of having tumor-induced osteomalacia. A Ga-DOTANOC PET/CT was performed for localization of the causative tumor. The images demonstrated intense radiotracer accumulation in a soft tissue nodule in deep lobe of the right parotid gland. Subsequent surgical resection and pathologic analysis confirmed the diagnosis of parotid basal cell adenoma.
