Imaging of Mixed and Radiopaque Jaw Lesions

This article describes the most characteristic and prevalent radiopaque and mixed lesions of the jaws and their imaging characteristics. Paget's disease, fibrous dysplasia, and rare sclerotic bone diseases of the maxillofacial bones are discussed elsewhere in this issue. Careful correlation of clinical presentation, panoramic radiographs, cone beam computed tomography, and histopathology are the cornerstones for appropriate lesion characterization.

(International Osteoporosis Foundation) A new special edition of 'Calcified Tissue International' provides expert commentary and insight into the advances in the knowledge of several rare focal and sclerotic bone diseases including Paget's disease of bone and related syndromes, fibrous dysplasia of bone and McCune-Albright syndrome, Melorheostosis and Osteopoikilosis, chronic non-bacterial osteomyelitis, as well as Camurati-Engelmann disease.

This article presents a case of treponemic disease in a skeleton of a female adult found at Los Tres Cerros 1 archaeological site (Upper Delta of Paran á River, Entre Ríos, Argentina). This site was occupied by hunter–gatherer–fisher groups that also practised horticulture during the Late Holocene (ca. 1227–560 years BP). A macroscopic description of bone lesions is complemented with data from X‐rays and CT scans. Different types of lesi ons were observed in the left ulna, femora, right patella, tibiae, and fibulae. In addition, two remodelled depressions surrounded by bony thickening...

Abstract Nuclear medicine studies evaluate physiology on a molecular level providing earlier detection of lesions before morphologic change is evident. 99mTc-MDP and 18F-fluoride bone scans detect osteomyelitis earlier than radiographs and computed tomography (CT); aid in diagnosis of temporomandibular joint disorder; and evaluate activity of condylar hyperplasia, extent of Paget disease, and viability of bone grafts. 18F-FDG PET/CT distinguish between soft tissue and bone infections and diagnose osteomyelitis complicated by fracture or surgery. FDG PET is more accurate than CT alone and has a major role in stagin...

Positron emission tomography with the radiotracer 18F-fluoro-2-deoxy-d-glucose (FDG) plays an important role in the evaluation of bone pathology. However, FDG is not a cancer-specific agent, and knowledge of the differential diagnosis of benign FDG-avid bone alterations that may resemble malignancy is important for correct patient management, including the avoidance of unnecessary additional invasive tests such as bone biopsy. This review summarizes and illustrates the spectrum of benign bone conditions that may be FDG-avid and mimic malignancy, including osteomyelitis, bone lesions due to benign systemic diseases (Brown t...

Osteosarcoma is the most frequent malignant bone tumor in the first decades of life. However, the etiology of this tumor is still unknown. Its main risk factors include prior radiotherapy, Paget ´s disease, fibrous dysplasia and chronic osteomyelitis, among others. It rarely affects the head and neck region, with only 4% occurrence in the jaws. A 36-year-old male patient was referred to our institution presenting a swelling in the lower right alveolar ridge with 6 months of duration. He al so reported hypoesthesia in this region.

Conclusions Given the incidence of benign bone lesions, it is important for PET/CT readers to be familiar with characteristic imaging features of common benign bone lesions in order to accurately stage malignancies. Facility with the entities displayed herein may help interpreting physicians (particularly trainees) differentiate a benign lesion from a focus of osseous metastatic disease, which is of the utmost importance in the oncology patient population commonly imaged with FDG PET/CT.

The objective of this study was to describe the main diseases that can present with this radiologic sign, such as Hodgkin lymphoma, Paget's disease, metastatic prostate cancer, breast cancer, and osteomyelitis. It is extremely important that radiologists be aware of this finding in order to inform the requesting physician of the possible etiologies, given that it can be the initial radiologic presentation for these diseases.Resumo Pacientes com dor lombar são frequentemente atendidos em todos os níveis de saúde.

Abstract In this paper, we describe pathological lesions identified in seven skeletons discovered in the Saint Sava necropolis in Bucharest, Romania, dating to the Late Medieval/Early Modern period. The pathological changes observed in the skeletons were analysed using macroscopic examination. Additionally, computed tomography scanning was performed on two individuals displaying advanced lesions on the cranial surface. For the differential diagnosis, we took into consideration treponemal infection, tuberculosis, osteomyelitis, leprosy, fluorosis, melorheostosis, hypertrophic pulmonary osteoarthropathy, Paget's disease and ...
