BACKGROUND AND PURPOSE To evaluate the CT characteristics of focal hyperostosis in patients with sinonasal inverted papilloma and to correlate these characteristics with the detection of the origins of tumors. MATERIALS AND METHODS Paranasal sinus and nasal cavity CT images of 76 patients were reviewed retrospectively to detect areas within which there was focal hyperostosis. We correlated th...

Sternocostoclavicular hyperostosis (SCCH) is a chronic osssifying diathesis affecting mostly juxtasternal structures and the inflammatory osteitis part of synovitis, acne, pustulosis, hyperostosis, (SAPHO) syndrome.

A 50-year-old female presented with more than 20-year history of a large subcutaneous mass in the left parieto-occipital portion. Magnetic resonance (MR) imaging revealed the lipomatous mass to show a high signal intensity in both T1- and T2-weighted images. A part of the lipomatous lesion progressed into the underlying hyperostosis and skull. The preoperative diagnosis was skull invasion of a ...

Hyperostosis frontalis interna is an unexplained irregular thickening of the inner table of the frontal bone. Hyperostosis frontalis interna was first identified in 1719 by Morgagni as a symptom of a more generalized syndrome characterized by virilism and obesity. Most current studies have shown hyperostosis frontalis interna to be a sex- and age-dependent phenomenon, and females manifest a sig...

This report described radiographic and CT features of atypical diffuse idiopathic skeletal hyperostosis in a 5 year-old, female Shih-tzu showing marked proliferative bone lesions in the appendicular skeleton with minor spinal changes. Continuous or flowing bony bridge formation of vertebrae is used as the gold standard for diagnosing diffuse idiopathic skeletal hyperostosis. However, this crite...

BACKGROUND AND PURPOSE Periosteal new bone formation and cortical hyperostosis often suggest an initial diagnosis of bone malignancy or osteomyelitis. In the present study, we investigated the cause of persistent bone hyperostosis in the offspring of two consanguineous parents. METHODS Clinical assessment, imaging, and direct sequencing were used to elucidate the etiology of the condition see...

introduction camurati-engelmann disease (ced) is a rare autosomal dominant disease with various phenotypic expressions. the symptoms usually develop during childhood. the hallmark of the disease is bilateral symmetric diaphyseal hyperostosis of the long bones with progressive involvement of the metaphysis. the epiphysis is strictly spared. the common clinical symptoms are pain of the extremitie...

In this paper the alterations of the skeleton of a 42 year old, Bornean Orangutan (Pongo pygmaeus pygmaeus, Linnaeus, 1760) are described. The skeleton showed typical hyperostosis and calcification on the right side of the thoracic vertebrae, consistent with the skeletal disease known in human pathology under the name of Diffuse Idiopathic Skeletal Hyperostosis (DISH, ankylosing hyperostosis). ...

Diffuse Idiopathic Skeletal Hyperostosis versus Ankylosing Spondylitis: Brief Case Review D idiopathic skeletal hyperostosis is an idiopathic form of degenerative arthritis. It is usually characterized by exuberant bony growth along the anterior longitudinal ligament and typically affects males over 60 years of age. Diffuse idiopathic skeletal hyperostosis, previously known as Forestier’s disea...
