We report on a 28-year-old man with severe headache. Imaging studies included CT and MR. A large sphenoid mucocoele was demonstrated as well as findings compatible with fibrous dysplasia of the facial bones. Both disorders had been previously unknown. Imaging findings suggested that the sphenoid mucocoele was related to an obstruction caused by the expansile bone of fibrous dysplasia. These fin...

INTRODUCTION Desmoplastic fibroma is an extremely rare primary benign bone tumor. It occurs most often in the mandible, followed by the femur and pelvis. To the best of our knowledge, fewer than 200 cases have been described in the published literature. Furthermore, this case is the first report of desmoplastic fibroma with simultaneous presentation in two different locations. CASE PRESENTATI...

Osteochondromas are common benign tumours of bone that often occur in the metaphysodiaphyseal parts of long bones. They rarely occur in the spine. We present a case of solitary osteochondroma arising from the C-1 vertebral lamina, causing neurological symptoms. A 46-year-old man presented to our institution, complaining of pain and numbness originating from his neck and extending down to his le...

PDB (Paget's disease of bone) is a common condition characterized by focal increases in bone turnover affecting one or more sites throughout the skeleton. Genetic factors are important in the pathogenesis of PDB and many families have been described where PDB is inherited in an autosomal-dominant fashion. Several candidate loci for susceptibility to PDB and related syndromes have been identifie...

An aneurysmal bone cyst (ABC) is a rare, non-neoplastic, destructive, hemorrhagic and expansile lesion accounting for 1% of all bone tumors. This type of lesion predominantly affects long bones and vertebrae. ABC of the metatarsal is rare and only a few cases have been reported in the literature to date. The present study reports a rare case of ABC of the third metatarsal occurring in a 27-year...

congenital vascular lesions occur most often in children. parents of these children take them to maxillofacial surgeons directly or during the treatment of other complications such as infection or jaw bone disorders. various terms now used are unable to describe the pathogenesis and mechanism of the effect of vascular lesions on growth and development of facial bone.  term of hemangioma is used...

Background: Bone lesion in multiple myeloma (MM) is most commonly presented as a lytic lesion in this disease. Determination of extent of bone lesions in MM is necessary to follow-up the patients. Whole body bone scan with 99m, Tc-methylene diphosphonate (MDP) has a lower sensitivity than other modalities. Methods: From the patients with MM admitted to Ayatollah Rouhani Hospital of Babol-Iran ...

BACKGROUND 1% of all bone tumors are Chondroblastomas. Chondroblastomas, initially considered to be an osteoclastoma variant are benign, cartilaginous tumors which usually occur in the epiphysis of long bones, es...
