Aneurysmal bone cysts (ABCs) are relatively uncommon, benign lesions. Fully 50% occur in long bones and 20% in the vertebral column, mostly in patients under 20 years of age. We report a case of an ABC in the odontoid process of a 74-year-old who sought treatment for pain and myelopathy. This is the first case reported of an ABC of the odontoid process.

Aneurysmal bone cyst is a relatively uncommon bone tumor. Six children treated between February 1985 and May 1987 with an operative approach involving insertion of several Kirschner pins across the tumor area are reviewed. Postoperatively, pain relief and varied healing of the lesion was noted radiologically. We conclude that it is worthwhile to consider insertion of Kirschner pins as a first step in treatment.

A 31-year-old female came to our hospital complaining of left frontal bulging with pain on 10 August 2000. The head x-p showed a radiolucent lesion and bulging at the same calvarial site. CT scan and MRI showed fluid-fluid levels, diploic cyst, deformity and hypertrophic calvarial change. There was a partial hypervascular part of cyst adjacent to the left frontal base by selective left external carotid angiography. Harmonic image is a contrast specific imaging modality that uses the nonlinear properties of contrast agents by transmitting at the fundamental frequency and receiving at multiples of these frequencies. Pulse inversion harmonic image(PIHI) using pulse inversion to eliminate and strengthen the harmonic frequency is more effective than conventional harmonic imaging. Transcranial sonographic examination showed hyper- and hypoechoic appearances in the cyst around abnormal hyperechoic appearances of the calvarial site. The transcranial contrast sonographic images with PIHI (hereinafter TCIpi) demonstrated an enhanced intracystic lower stratum and nearby the diploic part. That modality facilitates better visualization than the harmonic imaging method, enabling differentiation of vascular from avascular areas. As contrast agents are microbubbles, those are restricted in the vascular canal space. So TCIpi findings proved to be a blood circulation of the tumor, cyst and neighboring tissue. Enhanced areas changed by every minute and disappeared gradually. The findings were probably based on the vascular component of the tumor. We obtained images similar to those with CT and MRI. The patient underwent on 21 August. The tumor was removed along with the surrounding skull component. Fresh and old blood were mixed in the cyst. The clinical and pathological diagnosis was aneurysmal bone cyst. The postoperative course was uneventful and she was discharged on 29 August. Aneurysmal bone cyst is a rare calvarial tumor. An diagnostic finding is fluid-fluid levels that appear in approximately 30% of aneurysmal bone cysts. However, this is not a specific finding and has also been reported to occur in osteosarcoma, malignant fibrous histiocytoma, fibrous dysplasia, synovial sarcoma, hemangioma and simple bone cyst. Therefore, diagnosis of aneurysmal bone cyst is based on a combination of the various imaging applications, clinical and pathological findings. Gometz reported that sonographic examination was superior to any diagnostic imaging studies for aneurysmal bone cyst. Furthermore, the perfusion examination like TCIpi can directly observe blood circulation channels in tissue, so the specific enhancement changes of aneurysmal bone cyst could be observed. TCIpi is a useful method for diagnosis of aneurysmal bone cyst.

Aneurysmal bone cyst is an uncommon nonneoplastic lesion that occurs predominantly during the first 2 decades of life. Angiographic- and tissue-phase imaging provided more striking evidence of this unexpected lesion than skeletal-phase imaging in a 13-year-old girl with pain in the right buttock and posterior thigh.

Aneurysmal bone cyst is a rare, rapidly growing, and destructive benign bone tumor that even more rarely involves the bones of the hand. Various treatment options for aneurysmal bone cyst have been reported in the literature, but controversy exists regarding optimal treatment. Due to its rarity in the hand, no evidence-based treatment regimen has been established. A 21-year-old man presented with a history of pain and local swelling over his fifth metacarpal of 5 months' duration. Physical and radiographic examination of the hand was consistent with aneurysmal bone cyst. After biopsy, pathologic examination confirmed the diagnosis of aneurysmal bone cyst. En-block resection of the tumor and autologous bicortical strut graft fixation with Kirschner wires was performed. The hand was immobilized in a short arm cast for 3 weeks after the patient received 3 weeks of physiotherapy. Kirschner wires were removed 6 weeks postoperatively. Excellent clinical and functional results were obtained with no recurrence after 3 years of follow-up with en-block resection and reconstruction with iliac crest graft. Radiographic examination demonstrated the osseous integration of the graft with no signs of recurrence. Although treatment should be planned individually according to lesion site and size and to patient age, we suggest en-block resection to prevent recurrence and secondary surgical interventions particularly in cases with no articular involvement.

Aneurysmal bone cyst is a benign usually expansile, solitary lytic lesion of bone; with blood filled cystic cavities, which tend to grow eccentrically. Such eccentric growth may, on occasion, attain considerable size before it is clinically recognized, particularly if the tumor arises in a deeply situated bone. Aneurysmal bone cyst of pubis is a rare entity. In the following case report, an aneurysmal bone cyst, originating from the superior pubic ramus, expanded into the groin and first manifested itself as a gradually increasing fullness in groin and pain especially with weight bearing. The size and location of this vascular tumor posed difficulties in treatment. It was managed by curettage with high speed burr and reconstruction of the defect with an iliac crest cancellous bone graft.

Aneurysmal bone cyst accounts for 1% of primary bone tumors and is one of the benign tumor-like lesions. Patellar involvement is quite rare. Its development on the basis of any previous lesion such as chondroblastoma is called secondary aneurysmal bone cyst. A 26-year-old male patient presented with right knee pain of three-year history. Physical examination showed a firm, immobile swelling at the anterior aspect of the right knee, without increase in temperature or redness of the skin. There was no pain on palpation and joint range of motion was normal. Radiological studies were suggestive of an aneurysmal bone cyst. At surgery, the cystic lesion was removed via curettage and the residual cavity was filled with an autogenous bone graft taken from the iliac wing. The histopathologic diagnosis was secondary aneurysmal bone cyst in association with chondroblastoma. During a 1.5-year follow-up, the patient had no complaint and no recurrence was observed.

Aneurysmal bone cysts are often localized in long bones of the lower extremity and are characterized by aggressive expansion with local destruction of bone. We present the case of a 14-year-old female patient with a two weeks history of low dorsal pain. Computerized tomography (CT) scan of the spine showed local destruction of the 10th thoracic vertebra and magnetic resonance imaging (MRI) revealed a 50 percent compression of the spinal cord. The partly septated and partly solid cystic tumour in the 10th thoracic vertebra was resected and a dorsal spondylodesis stabilised the thoracic spine. Aneurysmal bone cyst should be considered in the differential diagnosis of unspecific pain of the spine. Follow-up examinations after three, five and twelve months did not show signs of recurrence.

Aneurysmal bone cysts (ABCs) are destructive cystic lesions of the bone and are common in children. They are expansile in nature and, therefore, may become symptomatic. These have traditionally been treated surgically; but recently, endovascular embolization has shown promise as a stand-alone therapy. The authors describe a case of an ABC highlighting the effectiveness and efficiency of endovascular treatment. A 16-year-old boy was referred for a 4-month history of radiating back pain and urinary hesitancy. Findings from his neurological examination were normal, but he had problems ambulating because of pain. Magnetic resonance imaging and CT scanning showed a cystic mass in the sacrum; a biopsy was performed and diagnosis of ABC was confirmed. Treatment options were then discussed with the family. The patient underwent 2 endovascular embolizations in approximately 1 month: Onyx 18 was involved in the first session, and N-butyl cyanoacrylate glue was used in the second session. After the first treatment, the patient experienced a dramatic decrease in pain and concomitant improvement in function. The patient went from being mildly symptomatic after the first treatment to completely asymptomatic after the second treatment. Clinical and radiographic follow-up obtained at 2, 6, and 18 months after initial treatment revealed the patient to be asymptomatic with progressive ossification. Endovascular treatment can be effective in treating symptomatic cases of ABC in which surgery would carry significant risk. Selective arterial embolization can promote sclerosis and result in an immediate and significant decrease in pain.

Aneurysmal bone cyst of the foot is extremely rare and the involvement of medial cuneiform has never been reported in the literature. In this report, we describe a 15-year-old boy who presented with a 6-month history of pain and swelling in his left foot. Radiograph demonstrated a lytic lesion in the medial cuneiform extending on to the middle cuneiform, the navicular bone and the base of the first metatarsal. En bloc resection of the lesion was performed using a dorsal longitudinal incision along the first ray. Tricortical iliac crest graft was harvested and shaped to fill the defect. Two drill holes were made and the tibialis anterior tendon was attached to the graft. Prepared, morcellised allograft was placed along the junction of autograft and host bone. At 1-year follow-up, the patient was pain free, the medial arch of the foot was maintained and the graft had united with the host bone.
