52/M with difficulty in walking since 7 months and proximal myopathy since 7 years. Preoperative biochemical parameters: Serum calcium - 7.5 mg/dL, serum phosphorus – 0.7 mg/dL serum parathyroid hormone – 277.4 pg/ml, serum creatinine – 1.3 mg/dL, serum alkaline phosphatase – 1093 U/L. Fluorodeoxyglucose contrast enhanced positron emission tomography-computed tomography images (a) maximum intensity projection image showing brown fat uptake and focus of increased fluorodeoxyglucose uptake in the region of greater trochanter of left femur (arrow). (b) Transaxial and (c) coronal contrast-enhanced computed tomography and corresponding fused contrast enhanced positron emission tomography-computed tomography showing fluorodeoxyglucose uptake in focal sclerotic lesion in the greater trochanter of left femur (maximum standardized uptake value 6.9). Postoperative serum calcium – 9.4 mg/dL, serum phosphorus 2.8 m/dL
