Aneurysmal bone cyst (ABC) is a benign bone tumour characterised by rapidly expanding osteolysis. The nomenclature was proposed by Jaffe and Lichtenstein (1942), who also determined the nature of the lesion. Between 9% and 12% of all aneurysmal bone cysts occur in the spine (Campanacci, Capanna and Picci 1986), presenting with back pain and symptoms resulting from cord or root compression and f...

Aneurysmal bone cysts mostly occur in long bones and spine. It is relatively rare in the maxillofacial region. In this article, we present a 19-year- old woman with the complaint of swelling in the left mandibular premolar tooth. She had got antibiotic therapy after the diagnosis of dental cellulites. On the X-ray study, a well- defined unilocular bony lesion within the preapical premolar tooth...

The aneurysmal bone cyst is a pseudotumoral lesion that can take several aspects. This is a rare lesion representing 1% of bone tumors. It appears usually during the first 30 years of life. The pathogenesis is that of a process of "dysplasia/hyperplasia", favored by a circulatory deficiency and hemorrhage within the lesion and the phenomena of osteoclasis. The objective of this work is to illus...

Chondroblastoma is a rare tumor. It is usually benign; however, it can have an aggressive course before or after operative treatment, even resulting in pulmonary metastases. The foot is a rare location for chondroblastoma, and to our knowledge, chondroblastoma occurring in the navicular bone has not been reported previously in the English literature. We describe a case of navicular chondroblast...

A 13 years boy presented with a painless hard and fixed swelling in occipital region for the last three months. Plain X-ray, CT scan and MRI showed an expansile multi loculated cystic lesion in occipital bone. Histopathological examination revealed it to be an aneurysmal bone cyst. Treatment of choice is surgery. However, radiotherapy may be helpful in incompletely excised lesions.

BACKGROUND AND PURPOSE Recent data suggest that percutaneous sclerotherapy is a safe alternative to surgery for treatment of aneurysmal bone cysts (ABCs). We present our experience of this method. METHODS We retrospectively analyzed data from 38 consecutive patients treated with repeated injections of polidocanol. Each injection consisted of 2-4 mg polidocanol per kg body weight. Radiological...

Three children presenting with aneurysmal bone cysts are described. The first patient was 10 months old with a cyst of the scapula. The second was more typical but his cyst was treated initially as a malignant tumour. In the third child the second cervical vertebra was affected which posed considerable problems of management; it was treated by radiotherapy. Despite the problems all 3 children h...
