Sinonasal inverted papilloma is a benign neoplasm of epithelial origin, which represents 0.5 to 4% of all sinonasal tumors. Despite the histological benign nature of this type of tumor, it has a high rate of recurrence after surgical resection and significant malignant potential. Sinonasal inverted papilloma is treated as a locally aggressive tumor. The aggressive surgical approaches, such as e...

Hyperostosis cranii or metabolic craniopathy was first recognised as an essential part of Morgagni’s syndrome of virilism, obesity and hyperostosis frontalis. It is a syndrome of uncertain origin which was believed to occur almost exclusively in middle aged and elderly women. More recently it has been shown to occur in younger women and rarely to occur in men. The syndrome is characterised by t...

OBJECTIVES Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by anterior ossification of the spine and can lead to dysphagia and airway obstruction. The morphology of the newly formed bone in the cervical spine is different compared to the thoracic spine, possibly due to dissimilarities in local vascular anatomy. In this study the spatial relationship of the new bone with the art...

PURPOSE To describe the MR and CT imaging features of hemangiopericytoma and to identify the characteristics that might distinguish them from meningioma. METHODS We retrospectively reviewed the CT and MR findings in 34 pathologically proved cases of hemangiopericytoma. We evaluated the size, shape, and location of the tumor; the presence of hydrocephalus, edema, and mass effect; the type of d...

BACKGROUND Sclerosteosis is a rare bone disorder characterized by a progressive craniotubular hyperostosis. The diagnosis of sclerosteosis is based on characteristic clinical and radiographic features and a family history consistent with autosomal recessive inheritance. The skull overgrowth may lead to lethal elevation of intracranial pressure, distortion of the face, and entrapment of cranial ...

An infant in hospital unexpectedly developed infantile cortical hyperostosis (Caffey's disease) while under-going treatment for an unrelated illness. The presentation of the disease was classic and there was marked thrombocytosis. The aetiological possibilities are discussed.

Bony hyperostosis is commonly associated with meningioma growth and is considered one of the characteristic signs on imaging; however, recurrence of meningiomas in the sphenoorbital area, including associated hyperostosis, is typically precluded by gross total resection of the lesion. This 63-year-old man presented with progressive double vision and proptosis in the right eye. He underwent fron...

The genetic aspects of infantile cortical hyperostosis are discussed. A pedigree is presented, based on the history and clinical and radiological investigations of all living members of the family, with data from 11 cases with the condition in two generations, and one possible case from a third generation. The data suggest that an autosomal dominant gene with varying expressivity could be respo...
