Abstract
Many diseases result in polyostotic bone lesions including benign entities, benign entities with malignant potential, intermediate entities, and malignant entities. Imaging plays a key role in identifying complications of these disorders, most importantly malignant transformation of a benign lesion. The most common polyostotic bone lesions are reviewed and examples of malignant transformation are highlighted.

Abstract
Lesions in the olecranon are rare and may be identified during the investigation of a clinically suspected abnormality or as an incidental finding. This review describes the spectrum of tumours and tumour-like lesions that can involve the olecranon and illustrates the radiographic, CT, and MRI appearances that may facilitate diagnosis. A variety of pathological processes affecting the olecranon are presented and discussed including the epidemiology and imaging features.

Abstract
Subtrochanteric femur fractures result from a variety of mechanisms of injury and underlying pathologies. Radiologists can play a pivotal role by differentiating the etiology of a subtrochanteric femur fracture, which assists the orthopedic surgeon in choosing the correct method of treatment. To provide this valuable service, one must be familiar with the characteristic radiologic features of the numerous causative etiologies, ranging from Paget disease to underlying bone lesions to iatrogenic fractures.

Abstract
Computed tomography (CT) has become the standard of care for evaluation and follow-up for a wide range of abdominal and pelvic pathology. Many incidental osseous and articular abnormalities of the pelvis are detected on these studies, most of which have a benign etiology. However, most of these studies are interpreted by nonmusculoskeletal radiologists, who may not be familiar with the CT appearances of these benign musculoskeletal abnormalities. Uncertainty often leads to mischaracterization or unnecessary follow-up, resulting in increased health care costs and patient anxiety. This article reviews the CT appearance of the benign musculoskeletal entities that occur in pelvis.

Abstract
General orthopedic surgeons frequently encounter patients with conditions affecting multiple bones. It is important to recognize common polyostotic diseases. This article describes five polyostotic conditions: Multipe Enchondromatosis (Ollier Disease and Maffucci syndrome), Multiple Hereditary Exostosis (Diaphyseal Aclasis), Fibrous Dysplasia (McCune-Albright syndrome and Mazabraud syndrome), Paget's Disease of bone (Osteitis Deformans), and Skeletal Metastases. This is a survey of the clinical, pathologic and radiographic features that assist in diagnosing these conditions. Also, an overview of the laboratory findings, treatment, follow-up, and prognosis is presented. Recognizing these diseases will aid in prompt and accurate diagnosis and appropriate referral and therapy.

Skeletal metastatic carcinomas from the Roman period (1st to 5th Century AD) in Hungary. Pathobiology 2014; 81:100-11.

Abstract
OBJECTIVES According to paleopathological records, tumors have a great antiquity. The prevalence of cancer in ancient populations might have differed from that in modern humans because of substantial differences in environmental factors, life expectancy and the availability of treatment. This study presents 3 cases of probable skeletal metastatic carcinoma from the Roman period (1st-5th century AD) in Hungary, showing the development of bone metastases of cancer without chemo- and radiotherapy. METHODS All skeletons were subjected to a careful macroscopic investigation, which was extended by radiological, stereo- and scanning electron microscopic analyses. RESULTS In 1 case, the mixed nature and localization of the lesions, as well as the sex and age of the individual, suggested breast cancer as the primary focus. In the other 2 cases, based on the mostly osteoblastic nature and the localization of the lesions as well as on the sex and age of the individuals, the most probable diagnostic option is prostate carcinoma with skeletal metastases. CONCLUSIONS In view of the scarcity of cancer metastases that have been diagnosed in archeological specimens in general, identification of all examples of cancer in antiquity represents an important contribution both to paleopathology and to modern medicine.

Malignant degeneration of multilevel monostotic Paget's disease involving the thoracic spine: an unusual presentation. J Clin Neurosci 2014; 21:1254-6.

Abstract
Paget's disease is the second most common metabolic bone disease after osteoporosis and is characterized by abnormal bone turnover and remodeling that can lead to pain, pathological fracture, bony deformity and nerve compression syndromes. The lumbar region is the most commonly affected site within the spine followed by the thoracic and cervical spine. Even though the spine is affected very commonly in Paget's disease, malignant degeneration is exceptionally rare. Multilevel monostotic spine involvement due to Paget's disease is very uncommon. An unusual clinico-radiological manifestation of multilevel thoracic Paget's disease with sarcomatous degeneration presenting as a neurosurgical emergency is reported with a pertinent review of the literature.

Abstract
Paget's disease is an osteoclastic-mediated disorder of bone that results in abnormal bone resorption associated with inadequate remodeling that leads to mechanically weakened bone. Demonstrating variable geographic prevalence, it is becoming less frequent and age of onset is lengthening in areas of once high prevalence prior to the institution of effective medical therapies, suggesting its etiology involves both environmental as well as genetic factors. Insights into its pathophysiology are helping to clarify other inherited osteolytic disorders of bone by providing additional insights into related cellular processes.

Abstract
Paget disease of bone (PDB) is a chronic progressive disease of the bone of uncertain etiology, characterized initially by an increase in bone resorption, followed by a disorganized and excessive formation of bone, leading to pain, fractures, and deformities. It can manifest as a monostotic or polyostotic disease. The prevalence of PDB is common in the Anglo-Saxon population, but relatively rare in India. The disease is often asymptomatic and commonly seen in an aging population. The diagnosis of the disease is mostly based on radiological examination and on biochemical markers of bone turnover. Markedly elevated serum alkaline phosphatase (SAP) is a constant feature while calcium and phosphate levels are typically within normal limits. It is being successfully treated by biphosphonates, a group of anti-resorptive drugs, thereby decreasing the morbidity and mortality associated with the disease. We report a classic case of PDB with craniofacial involvement resulting in Leontiasis Ossea (lion like face), cotton wool appearance of the skull and elevated SAP.

Abstract
We report a 73 years old man with a diagnosis of Paget Disease (PD) and symptomatic Multiple Myeloma (MM). Coexistence of MM and PD has rarely been described. PD mimics many of the features of bone destructive process in MM, making differential diagnosis more complicated. In addition, the presence of serious muscolo-skeletal and metabolic complications in both diseases makes management of patients difficult, worsening the prognosis. The comparison of these two diseases has led to the characterization of a common molecular mechanism represented by the receptor activator of nuclear factor-kB ligand (RANKL)/Osteoprotegerin signaling pathway. The improved comprehension of these mechanisms led to the development of new pharmacologic agents (bisphosphonates, cytokines inhibitors) effective for the treatment of these bone diseases.
