The patella is an unusual location for primary and metastatic bone tumors to develop. The most frequently encountered primary osteolytic lesions at the patella include giant cell tumors of the bone (GCT), chondroblastoma and aneurysmal bone cysts (ABC). However, the presentation of an ABC originating secondary to a GCT at the patella is rare. The present study describes such a case in a 46-year...

Angiosarcoma of bone is an exceedingly rare primary bone malignancy that can present as an aggressive osteolytic lesion. Histological diagnosis can be extremely challenging, as the pathological features often resemble that of aneurysmal bone cysts. We report an interesting and peculiar case of an intraosseous angiosarcoma that presented as a diagnostic dilemma and discuss the relevant radiologi...

Aneurysmal bone cyst (ABC) is a benign, expansile, non-neoplastic lesion of the bone, characterized by channels of blood and spaces that are separated by fibrous septae. Giant ABC is an uncommon condition and can be difficult to handle because of the destructive effect of the cyst on the bones and the compressive effect on the nearby structures, especially in weight-bearing bones of the body. W...

Aneurysmal bone cyst (ABC) is a benign osteolytic bone neoplasm characterized by blood filled spaces separated by fibrous septa. The tumor can have an occurrence anywhere that there is bone. It occurs mostly in extremity bones, whereas in skull and mandible bones its incidence is about 4%. In this article an unusual case of aneurysmal bone cyst in the right temporal region with histopathologica...

A neurysmal bone cyst was first described by Jaffe and Lichtenstein in 1942. It is considered a benign, locally aggressive lesion with a potential for local recurrence, and it typically appears in the metaphysis of the long bones and in the vertebral column. Mostly, children and young adults are affected. No sex predilection has been observed. Radiographically, aneurysmal bone cyst is seen as a...

We report the nonoperative treatment of a recurrent, multilevel spinal aneurysmal bone cyst by injection of 32P chromic phosphate colloid into the cyst. The patient was then followed up with serial CT examinations, which showed stabilization and progressive ossification within the lesion. The rationale, alternatives, and possible contraindications to radionuclide ablation of spinal aneurysmal b...

Aneurysmal bone cysts (ABCs) are rare benign bone tumours. Scapula is a very rare location, and the relative literature is sparse. The purpose of this study is to present a case of a giant aggressive scapular aneurysmal bone cyst in a child. A 7-year-old boy presented to our hospital with pain and a palpated mass on the right scapula. Imaging studies (radiographs computed tomography scintigraph...
