The need to initiate treatment for a postmenopausal woman with a low bone mass should be based on that individual's fracture risk over a fnite period of time. Fracture assessment tools, such as the recently introduced FRAX(TM) model, allows the clinician to estimate an individual's absolute fracture risk over the next decade of their life. Such estimates are particularly useful for younger post...

Solid variant aneurysmal bone cyst is a rare benign bone lesion, representing a small fraction of all aneurysmal bone cysts. The imaging appearance and histologic features may overlap with other benign and malignant neoplasms, posing a diagnostic dilemma for clinicians, pathologists, and radiologists. We present a case of solid variant aneurysmal bone cyst of the distal fibula and review the ra...

Aneurysmal bone cyst is an uncommon bone lesion which rarely occurs in craniofacial region. Among all the cystic lesions occurring in the jaws, aneurysmal bone cyst is infrequent and it more commonly occurs in the mandible. Most of the cases occur in the first two decades of life, with no gender predilection. Here, we are presenting a case of an aneurysmal bone cyst which occurred in the mandib...

Angiosarcoma of bone is an exceedingly rare primary bone malignancy that can present as an aggressive osteolytic lesion. This subset can radiologically mimic non-vascular neoplasms and impose serious challenges in reaching the correct diagnosis. Meanwhile histological diagnosis can be extremely challenging too, as the pathological features often resemble that of aneurysmal bone cysts. We presen...

Four year old girl was evaluated for precocious puberty. Breast development and pubic hair growth had started at age 2½ year, and had been followed by vaginal bleeding resembling periods. Gaf-au-lait spots were present in most of her skin surface. Bone x-rays showed multiple cysts in pelvis and the metaphysis of femur. Diagnosis of McCune-Albright syndrome was made. Concentrations of all hormon...

The treatment of pathological fractures of the humerus caused by juvenile or aneurysmal bone cysts (JBC/ABC) should be a single approach with a high success rate and low complication rate. This study evaluates how day by day treatment concepts fulfil these aims. Children below 15 years of age with a pathological fracture of the humerus caused by a JBC or ABC between 01.01.2001 and 31.12.2010, w...

The subject of this article is the state of a benign bone disease. The principle aim of this study is the construction of a statistical model for estimating the otherwise unobservable variable for the state of the disease. The distribution of intensity of X-ray images of the affected part and the healthy part of the bone are evaluated. Quantiles of both distributions are used in the estimation ...

Bone cysts are rare orthopaedic problems in dogs. There no clear treatment guidelines. A young male Shih Tzu was referred to Small Animal Clinic with fifth-degree lameness (5/5) of the left thoracic limb, and swelling deformation distal humeral region. The radiological assessment revealed an enlargement brachium extensive hypodense osteolytic lesion metaphyseal region humerus. Diagnosis b...

Aneurysmal bone cyst (ABC) is a benign, tumor-like, highly vascular, locally aggressive, and relatively rare osteolytic lesion of unknown etiology [1]. Treatment options for aneurysmal bone cysts are simple curettage with or without bone grafting, complete excision, embolization, radiation therapy, or a combination of these modalities [2,3]. Radical surgical excision should be the goal of surge...
