A 4-year-old boy developed progressive neck pain and an expansile osteogenic lesion of C2; the diagnosis was an aneurysmal bone cyst. An image-guided biopsy with 3D CT planning was performed followed by Ethibloc injection into the aneurysmal bone cyst. Subsequent CT and MR images demonstrated embolization material in the vertebrobasilar system, and the patient died of brain stem and cerebellar ...

Aneurysmal bone cysts (ABC) are rare and they represent 1- 1.4 % of all primary bone tumors. ABC of cuboid bone are extremely rare, especially in children. Very few cases have been reported in the literature since 1967. We present a case of pathological fracture of cuboid bone due to an aneurysmal cyst in a 10-year-old girl. Surgery was performed, which included open biopsy with aspiration and ...

BACKGROUND Aneurysmal bone cyst is an expansile bone lesion, non-neoplastic in nature, occurring most commonly in long bones. It is uncommon in facial bones and exceptionally rare in ethmoid bone. Ten cases of aneurysmal bone cysts of ethmoid bone have been reported so far. CASE REPORT A young adolescent presented with decreased vision and pain in the right eye. MRI revealed an expansile lesi...

The solid variant of aneurismal bone cysts (ABC) is considered rare. It occurs with greater frequency in pediatric patients and in the tibia, femur, pelvis and humerus. We present a case of a metaphyseal lytic lesion on the distal extremity of the radius in a child whose radiograph was requested after low-energy trauma. The hypothesis of a pathological bone fracture secondary to an aneurysmal b...

Aneurysmal bone cysts are a benign tumor of the bone, most commonly seen in the tibia, femur, spine and humerus. Cases of aneurysmal bone cysts in the foot, although rare, have been reported several times. To our knowledge, no case of aneurysmal bone cysts in the phalanx of a toe has been reported. We report a case of a primary benign bone tumor in the distal phalanx of the first toe in a 25-ye...

INTRODUCTION: Aneurysmal bone cyst is an uncommon in skull bone. The reported incidence in the skull is 1% of all aneurysmal bone cysts. Most of the cases are associated secondary phenomenon like pre-existing fibrous dysplasia. We present the imaging features and pathology of a primary ABC of the frontal bone, with no underlying bony abnormality or pre-existing trauma.

Aneurysmal bone cyst is a rare nonneoplastic expansile osteolytic bone lesion of unknown etiology. It usually occurs in the first 2 decades of life. The most common sites are the metaphysio-epiphyseal areas of long bones or vertebrae with eccentric expansion. We present a 42-year-old female with a huge aneurysmal bone cyst of the pelvis with dumbbell-shaped expansion on the both side of the ili...

Aneurysmal bone cyst (ABC) is blood filled expansile cystic lesion that most commonly occurs in patients during the second decade of their lives. Traditionally it has been described as a benign lesion but can be locally aggressive and result in the destruction of the involved bone. Treatment methods include surgical excision and curettage with or without bone grafting. We report a proximal femu...

Lichtenstein in 1942 and consists essentially of fibrous tissue honeycombed by vascular spaces. The lesion has been observed in many parts of the skeleton but it occurs especially in the shafts of long bones and in the vertebral column. It causes localised distension and destruction of the affected bone, limited peripherally by a thin bony shell (Fig. 1). In the past the lesion has usually been...
