INTRODUCTION Aneurysmal bone cysts are benign tumours that usually present in childhood. Aggressive forms have been described, which are often treated with surgery that entails major resection and reconstruction. Polidocanol sclerotherapy has recently been reported to have excellent results and promises to replace operative treatments, but its efficacy in the case of aggressive aneurysmal bone ...

PURPOSE Intraosseous cysts of carpal bones are frequently observed on routine imaging examinations of the wrist. There is controversy regarding the underlying pathogenesis of these cysts. In this study, we aimed to investigate the magnetic resonance imaging (MRI) appearance of intracarpal bone cysts in correlation with histologic analysis, using cadaveric wrists. METHODS Five freshly frozen c...

Diaphyseal unicameral bone cysts of the long bone are generally known to originate near the growth plate and migrate from the metaphysis to the diaphysis during skeletal growth. In the case of unicameral bone cysts of diaphyseal origin, recurrence at the same location is extremely rare. We report a case of recurrence of a unicameral bone cyst in the diaphysis of the femur that developed 8 years...

Background: Cystic echinococcosis (CE) is a zoonosis caused by the larve of Echinococcus granulosus. Cysts can develop in any part body, although liver and lungs are most frequently involved. Bone one rarest forms disease, accounting for 0.5 to 4.0% all echinococcosis. Spinal cysts disabling causing destruction similar malignant bone lesions, with high risk neurological deficit. Objectives: To ...

We report two cases of cystic lesions in the head and neck, one a cystic schwannoma and the other a neurofibroma, both of which showed fluid-fluid levels on MR images. The differential diagnosis of fluid-fluid levels in the head and neck region should include cystic hygromas, aneurysmal bone cysts, soft-tissue cavernous hemangiomas, and simple bone cysts.

BACKGROUND Various treatments for unicameral bone cyst have been proposed. Recent concern focuses on the effectiveness of closed methods. This study evaluated the effectiveness of demineralized bone matrix as a graft material after intramedullary decompression for the treatment of unicameral bone cysts. METHODS Between October 2008 and June 2010, twenty-five patients with a unicameral bone cy...

MR findings in a case of aneurysmal bone cyst of the temporal bone are described. MR can suggest the diagnosis of aneurysmal bone cyst and also give ancillary information that is helpful for surgical treatment.

In a recent communication Lichtenstein (1950) described in detail 8 cases of1 aneurysmal bone cysta new pathological entity. He and Jaffe first discovered the lesion in 1942 while reviewing their material pertaining to solitary unicamera bone cyst, and, between 1942 and 1948, they came across ' a dozen or more additional cases of the same lesion According to Lichtenstein, aneurysmal bone cyst i...
