Diffuse idiopathic skeletal hyperostosis is a disease of old age, in which there is bony proliferation of spine in ventral and lateral aspects of vertebral body. A 80-years-old male presented to us with features of low back pain radiating along the right lower limb in the posterolateral aspect. After examination and investigations, he was found to have metabolic syndrome, degenerative lumbar di...

Hyperostosis frontalis interna is a curious abnormality of the inner tables of the frontal bones of the skull, said to have been first described by Morgagni in 1761. It consists of aggregations of smooth, rounded enostoses which are covered by dura mater and project into the cranial cavity. Most are about 0 5 to 1 0 cm. in diameter at their bases and attain a similar height. The enostoses do no...

In diffuse idiopathic skeletal hyperostosis (DISH), recurrence of hyperostosis after surgical removal is common. While both non-steroidal anti-inflammatory drugs (NSAIDs) and radiotherapy have been used in the prevention of heterotopic ossification, only NSAIDs have been applied for prophylaxis in DISH. As a previously undescribed prophylaxis of recurrence in DISH, we report a case treated with...

Retinoic acid arthropathy typically presents in the axial skeleton as flowing ossification along the anterior longitudinal ligament and as a condition of pelvic hyperostosis. When the appendicular skeleton is involved, radiographic findings usually present late and are typically asymmetric. We present an unusual case of retinoic acid arthropathy presenting in both elbow joints. Radiologists sho...

BACKGROUND Forestier's disease, also known as diffuse idiopathic skeletal hyperostosis (DISH), is an idiopathic rheumatological abnormality in which exuberant ossification occurs along throughout the body, but most notably the anterior longitudinal ligament of the spine. CASE PRESENTATION We report on a 75-year-old white patient with progressive difficulty in swallowing and dysphagia, resulti...

Hyperostosis is the most common skull change associated with meningioma. Five hyperostosis cases of meningioma en plaque infiltrating the skull processed without previous decalcification of the bone tissue were investigated histologically and immunohistochemically with antibodies against somatostatin receptor 2A (SSR2A). Undecalcified bone biopsies embedded in methylmethacrylate and paraffin-em...
