Skeletal metastasis is one of the most important disabling complications of the malignant diseases. As in general, the survival of patients with osteometastatic lesions is relatively long, an early diagnosis can lead to improve the patient’s life, both quantitatively and qualitatively, and prevent exacerbation of the disease and disabling complications. In this study, 22 patients with est...

A 63-year-old man visited the clinic with numbness in the right hand. Magnetic resonance imaging demonstrated multiple low-intensity lesions in the cervical vertebrae and sacrum, which was suspicious of cervical bone metastasis. Fluorodeoxyglucose positron emission tomography/computed tomography revealed areas of increased fluorodeoxyglucose uptake in the thoracic esophagus, sternum and sacrum....

in this session, we will discuss 7 cases in pediatric musculoskeletal field. these cases will include different aspects of bone and msk disorders in pediatrics such as bone tumors (benign and malignant), bone involvement in metabolic and hematologic disorders, infectious diseases and soft tissue vascular lesions. during this session, we will ask some volunteered radiology residents to explain t...

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 hyperca...
