Bone metastasis is the most common diagnosis considered for lytic lesions in the bone. Parathyroid cancer presenting as overt bone disease with diffuse lytic lesions secondary to untreated hyperparathyroidism (HPT) is a rare entity nowadays. We report the case of a 50-year-old Chinese lady who presented with diffuse bone lesions consistent with Brown tumours, vertebral body collapse and hypercalcaemia mimicking bone metastasis and was later diagnosed with parathyroid cancer.
