1/177. Vertebra plana of the lumbar spine caused by an aneurysmal bone cyst: a case report.The patient was a 15-year-old girl who had a lesion of the fourth lumbar vertebra. Plain radiographs suggested vertebra plana, with complete collapse of the body of the fourth lumbar vertebra and no involvement of the intervertebral disk spaces. The presumptive diagnosis was eosinophilic granuloma. Progressive neurologic symptoms required surgical excision of the lesion, decompression, and fusion. Histopathologic examination of the operative specimen confirmed the diagnosis of an aneurysmal bone cyst.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
2/177. Recurrent aneurysmal bone cyst of the proximal phalanx treated with cryosurgery: a case report.A recurrent aneurysmal bone cyst of the proximal phalanx treated with curettage, cryosurgery, and bone grafting is presented. There is no evidence of recurrence after 5 years. Although cryosurgery is commonly used as an adjuvant for intralesional treatment for aneurysmal bone cyst, there have been no reports of its use for the treatment of a lesion arising in the hand.- - - - - - - - - - ranking = 1.4keywords = bone (Clic here for more details about this article) |
3/177. Pathological fracture in non-ossifying fibroma with histological features simulating aneurysmal bone cyst.A 12-year-old-girl presented with a fracture of an osteolytic lesion of the distal radius. A 7-year-old girl presented with a fracture of an osteolytic lesion of the femoral shaft. In both cases it was a non-ossifying fibroma with fracture misdiagnosed at pathology as aneurysmal bone cyst. Fractures through non-ossifying fibromas may alter the histological pattern of the initial lesion in two ways: firstly, by the presence of blood pigments due to the fracture, and secondly, by formation of new bone. Radiological-pathological correlation is essential to avoid histological errors after pathological fracture in a non-ossifying fibroma.- - - - - - - - - - ranking = 1.2keywords = bone (Clic here for more details about this article) |
4/177. Aneurysmal bone cyst of the coronoid process of the mandible.A rare case of an aneurysmal bone cyst (ABC) involving the right coronoid process of the mandible in a 12-year-old girl is presented. The characteristic features with fluid-fluid levels within the lesion observed on magnetic resonance imaging (MRI) and Computed tomography (CT) was helpful in the preoperative diagnosis.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
5/177. Recurrent t(16;17)(q22;p13) in aneurysmal bone cysts.Aneurysmal bone cyst (ABC) is a benign bone lesion for which no previous cytogenetic data exist. We describe the finding of clonal chromosome aberrations in three tumors; two had a t(16;17)(q22;p13) as the sole anomaly, and the third had a del(16)(q22) as the only change. These findings show that somatic mutations contribute to the development of ABC and furthermore indicate that bands 16q22 and 17p13 may harbor genes of importance in this process.- - - - - - - - - - ranking = 1.2keywords = bone (Clic here for more details about this article) |
6/177. Multilevel vertebral body replacement with a titanium mesh spacer for aneurysmal bone cyst: technical note.A 64-year-old male presented with abrupt tetraparesis caused by a minor impact. Diagnostic images obtained on admission showed an aneurysmal bone cyst visible in the cervical spine at the fourth to upper sixth level, although the patient had been wearing a halo brace to diminish the symptoms. The vertebral body from the fourth to the sixth level was dissected, and this space was packed with a titanium cage filled with ceramic bone fragments mixed with fibrin glue. The combination of a titanium cage and an anterior locking plate can be made easily for anterior spinal fusion with enough rigidity to maintain the necessary space during fusion without any major support equipment. Both edges of the titanium mesh cage cut into the vertebral body to hold the cage in place. The other part, the titanium plate, makes it secure until ceramic bone fragments in the cage promote bony ingrowth for fusion.- - - - - - - - - - ranking = 1.4keywords = bone (Clic here for more details about this article) |
7/177. Chondromyxoid fibroma of the scapula associated with aneurysmal bone cyst.A rare case of chondromyxoid fibroma of the scapula in a 21-year-old man is presented. This case is of interest because of its unusual site and association of aneurysmal bone cyst. Although chondromyxoid fibroma is uncommon bone tumor of the scapula, it should be considered in the differential diagnosis of expansile osteolytic lesion of the scapula.- - - - - - - - - - ranking = 1.2keywords = bone (Clic here for more details about this article) |
8/177. Aggressive aneurysmal bone cyst of the proximal humerus. A case report.The case of an 11-year-old girl with a rapidly expanding, massive lesion in the right proximal humerus is reported. After biopsy, surgical treatment of the aneurysmal bone cyst consisted of aggressive intralesional resection with autogenous tibial strut grafting for reconstruction. After followup of 17 years with no recurrence of disease, there is excellent graft incorporation and remodeling and excellent function of the shoulder.- - - - - - - - - - ranking = 1keywords = bone (Clic here for more details about this article) |
9/177. Aneurysmal bone cyst of the temporal bone.OBJECTIVE AND IMPORTANCE: Aneurysmal bone cysts (ABC) are benign bone neoplasms which typically involve the spine and long bones. We present a rare case of an ABC in the temporal bone with significant cerebellar compression. CLINICAL PRESENTATION: The patient was a young boy who presented with several weeks of left posterior auricular pain. Computed tomography, magnetic resonance imaging and angiogram showed an expansile bone neoplasm involving the left petrous temporal bone. INTERVENTION: A retrosigmoid-transmastoid craniectomy was performed, and total removal of the bone lesion was achieved. The pathological examination revealed the diagnosis of ABC. CONCLUSION: The postoperative course was uneventful, and the imaging studies demonstrated total removal of the neoplasm. This case represents the imaging and surgical management of a rare ABC in the temporal bone. This diagnosis should be considered in the differential of bone neoplasms in this region.- - - - - - - - - - ranking = 3.4keywords = bone (Clic here for more details about this article) |
10/177. Aneurysmal bone cyst of the orbit: a case report and review of literature.Aneurysmal bone cyst is a benign fibroosseous lesion which rarely occurs in the orbit. We report on a 7-year-old girl with aneurysmal bone cyst of the orbit who presented with painless proptosis and diplopia. optic nerve compression resulted in field loss and delayed visual evoked potentials. Radiological and histological features are discussed. The lesion was excised via a frontal craniotomy and the orbital roof reconstructed with a prefabricated titanium plate. Post-operatively a rapid resolution of the proptosis and diplopia followed. Previous reported cases of this rare entity in the orbit are also reviewed.- - - - - - - - - - ranking = 1.2keywords = bone (Clic here for more details about this article) |
