Aneurysmal bone cysts are uncommon benign, expansile, and lytic lesions that develop in childhood or early adulthood. An aneurysmal bone cyst usually occurs as a primary lesion. In one third of the cases reported in the literature, a preexisting condition or history of trauma is present. Pain and swelling are the main symptoms and usually last for as long as 6 months. Long bones are involved in...

An aneurysmal bone cyst is rare in the patella. We report the case of a 28-year-old woman who presented with chronic pain and no previous trauma history. Treatment included curettage of the cyst and filling with a corticocancellous graft. Thirty-one months after surgery, the knee was mobile and painless and graft incorporation was good.

BACKGROUND  Aneurysmal bone cysts are rare occurrences in the cervical spine. Surgical treatment in pediatric patients is a challenge. Complete tumor resection offers the best chance for cure. DESCRIPTION  Diagnosis and surgical management of an expansile aneurysmal bone cyst of the cervical spine involving all three spinal columns in a 10-year-old boy. RESULTS  Surgical treatment included ...

Juvenile ossifying fibroma (JOF) is a rare, benign, locally aggressive entity of the extragnathic craniofacial bones with a high tendency towards recurrence. Two distinctive microscopic patterns of juvenile ossifying fibroma have been described: a trabecular juvenile ossifying fibroma (TrJOF) and a psammomatoid juvenile ossifying fibroma (PJOF). Psammomatoid variant is predominantly a craniofac...

Aneurysmal bone cyst is a rare tumour-like lesion which develops during growth. Our aim was to determine the efficacy of the administration of percutaneous intralesional 3% polidocanol (hydroxypolyaethoxydodecan) as sclerotherapy. Between July 1997 and December 2004 we treated 72 patients (46 males, 26 females) with a histologically-proven diagnosis of aneurysmal bone cyst, at various skeletal ...

Fibrous dysplasia is a noninherited bone disease in which abnormal differentiation of osteoblasts leads to replacement of normal marrow and cancellous bone by immature bone with fibrous stroma. Monostotic fibrous dysplasia accounts for 28% in the ribs. It is often asymptomatic and incidentally detected on radiographs. As with many bone abnormalities, it can be superimposed by the formation of a...

Aneurysmal bone cysts are benign musculoskeletal tumours, which occur in young patients and, occasionally, with aggressive behaviour. Those tumours very often will need surgical treatment with curettage and bone grafting, but for aggressive lesions, inbloc resection is more advisable. Aggressive tumours use to be large and sometimes with difficult surgical approach and demanding complex surgica...
