Eccentric simple bone cysts of the femoral neck in adults.

The purpose of this communication is to describe atypical simple bone cysts of the femoral neck seen in adult patients. Two patients, aged 56 and 49, having cystic lesions which did not conform to a typical simple bone cyst, are reported. Common features including eccentric location, and thick lining tissue and sclerotic margin are not those of typical simple bone cysts seen in children. Local mechanical characteristics might be related to the atypical presentations.

[Aneurysmal bone cyst of C5. Complete 2-stage excision].

A case of aneurysmal bone cyst of the fifth cervical vertebra was unusual in that it occurred in a 35 year old man treated initially by radiotherapy (3,800 rads), within 3 years, worsening of clinical and radiologic signs led to a complete two-stage exeresis because of extension of lesion to body and posterior arch of C5. This male patient was 35 years old at diagnosis and 38 at time of surgery (respectively 1.2 and 2.5% of cases in the Hay series and 1.9% in the Ruiter series), this lesion affecting mainly age groups under 20 years. Aneurysmal bone cyst (ABC) constitutes 1.4% of primary bone tumors (Dahlin), and spinal localizations 3% (Biesecker), 14% (Reiter) or 20% (Tillman) of total ABC. The cervical lesion represents 13% (Reiter) or 22% (Hay) of spinal localizations, C5 being affected twice in the 17 cases reported by Ameli, and fills, according to Hay, 3.3% of all spinal column lesions and 15% of cervical lesions. Initial treatment applied in another center was by radiotherapy alone at the dose of 3,800 rads (the recommended dose-level in the literature being 20 to 30 Grays). Neither clinical nor radiologic improvement was reported. The recurrence rate after all types of treatment for ABC was 12.6%, and after radiotherapy alone was 11% in the Hay series, MacCarty reporting only one recurrence among 9 patients treated with irradiation alone.(ABSTRACT TRUNCATED AT 250 WORDS)

The traumatic bone cyst: a new dimension.

A case of an unusually large traumatic bone cyst of previously unreported size and location is presented. The presence of the cyst 5 years before its current discovery was confirmed on previous radiographs. This aggressive traumatic bone cyst adds another dimension to the usual course of this lesion.

Simple bone cyst: etiology, classification, pathology, and treatment modalities.

Simple bone cyst (SBC) is an enigma to the radiologist, pathologist and the orthopaedic surgeon. The etiology of this asymptomatic lesion that frequently causes pathological fracture is still unknown. It is probably self limited in nature, seen in children but rare among adults. The biological behavior is unpredictable as is the clinical course in various anatomical sites. This reflects on the high recurrence rate that has been associated with various treatment modalities. The clinical, radiological and biological features are discussed together with comparative review of treatment options from resection, curettage, and bone grafting to steroid injection and the latest experience of the use of percutaneous autologous marrow grafting in SBC.

[Aneurysmal bone cyst of the skull -a case report- (author's transl)].

Aneurysmal bone cyst of the skull is rarely seen. There are 29 reported cases in the literatures as far as we could collect. We reported an additional case of aneurysmal bone cyst of the skull which originated from the right parietal bone of 4-year-old boy. We have summarized these 29 cases. The age incidence in this series is from 14 month-old to 31 year-old. There are 11 cases under the age of 10. In most cases clinical symptoms are palpable mass or headache and exophthalmos. Eyeball displacement and proptosis are also the symptoms when this disease occurs at the orbital roof. According to the characteristic radiographic appearance, it is "blown-out pattern with a shell of periosteal new bone over the mass or soap-bubble appearance". However in our case the radiological finding was osteolytic. It is possible to remove totally when this lesion occurs in the cranial vault, but only curettage may be performed when the skull base is involved. Total removal is the best treatment. Radiation therapy is usually done in the recurrent cases. It is necessary to follow up for at least 4 years because of the rarity of recurrence beyond 4 years after the initial treatment. We also described the other differential diseases and pathogenesis of this disease.

A surgically treated unicameral (solitary) bone cyst of the talus with a 15-year follow-up.

Unicameral bone cysts are uncommon in the foot. When they do occur, they must be differentiated from a variety of other benign lesions. The author describes a unicameral bone cyst of the talus, and its surgical management. The patient returned 15 years later with complaint of mild ankle joint arthrosis, although recurrence of the cyst was not demonstrated.

[Aneurysmal bone cyst of the left 5th rib].

A case of aneurysmal bone cyst of the left 5th rib is reported. A 57-year-old male complained of palpable lump and pain on his back. Chest X ray and CT showed expansive tumor arid pathological fracture of the left 5th rib. The tumor and the adjacent segments of the 4th and 5th ribs were resected en bloc. The pathological examination showed multiple blood filled spaces and fibrous trabeculae, confirming the diagnosis of aneurysmal bone cyst. He has been followed up for 3 years and 6 months with no signs of recurrence.

Simple bone cyst: a discrepancy between magnetic resonance imaging and surgical observations.

OBJECTIVE: The purpose of this study was to compare magnetic resonance (MR) imaging and surgical observations of fluid in simple bone cysts. STUDY DESIGN: Findings during MR imaging of 7 simple bone cysts were compared with surgical observations 1 day or 1.8 months (mean) after MR imaging. RESULTS: All MR images showed cavities filled with fluid. In 2 patients operated on the day after the imaging, surgical observations were in accordance with the MR findings. At surgery 1.8 months after the MR examination, 4 cavities were found to be empty and 1 cavity contained only a minor amount of fluid. CONCLUSION: A discrepancy between MR imaging and surgical observations of fluid in simple bone cyst cavities was observed that might be dependent on the time between the observations, indicating that a fairly rapid absorption of fluid might occur or that the amount of fluid in a simple bone cyst can vary for unknown reasons.

Operative treatment of solitary bone cysts with tricalcium phosphate ceramic. A 1 to 7 year follow-up.

From 1984 to 1990 we treated 18 patients aged 5 to 15 1/2 years with solitary bone cysts of the humerus, the femur and the calcaneus. To fill the defect, tricalcium phosphate (TCP) instead of bone grafting was used. The clinical and radiological long-term results up to seven years postoperatively are reported. In 16 patients TCP was well incorporated without any adverse reaction to the synthetic material. Two patients with a recurrence of the bone cyst were successfully reoperated. We conclude that ceramics are a cheap and easy available substitute for bone grafts in the treatment of solitary bone cysts.

Aneurysmal bone cyst arising after anterior cruciate ligament rupture.

An aneurysmal bone cyst, a condition first described in 1942, is a relatively rare benign tumor. Approximately 1% of all primary bone tumors are aneurysmal cysts. Diagnosis is typically made in a patient's first or second decade and rarely follows trauma. This is the first reported case of an aneurysmal bone cyst arising after rupture of the anterior cruciate ligament.

Unicameral and aneurysmal bone cysts.

One hundred and seventy-eight cases of unicameral bone cysts (UBC) treated with curettage and bone grafting were compared to 141 cases treated with cortisone injections. The end results were comparable in the two groups. Local recurrence risk factors in the surgical group were active cyst and previous operations. In the other group they were multilocation of the cyst, active cyst, and size of cyst. A new radiographic classification of aneurysmal bone cyst (ABC) is proposed in a report of 198 cases of ABC. The treatment of choice in ABC is surgical and the type (curettage, curettage plus phenole or cryosurgery, resection or hemiresection) is selected on the basis of the radiographic aspect and the rate of growth of the cyst. Radiotherapy is only indicated in inoperable ABC cases.

Unusual bleeding of aneurysmal bone cyst in the upper thoracic spine.

Aneurysmal bone cyst (ABC) is a benign bone lesion and commonly affects young adolescents. It usually grows rapidly with hypervascularity. In the spine, it can cause extensive bone destruction and compress neural structures with eventual vertebral collapse. Operative management of such a lesion may be complicated by profuse hemorrhage. Herein, we report a 15-year-old boy who had an acute exacerbation of spinal cord compression because of an ABC in the upper thoracic region. With a two-staged operation that complicating with profuse intraoperative bleeding, decompressive curettage and stabilization of the vertebral column were assured. However, abrupt neurologic deterioration occurred because of rebleeding with spinal cord compression 1 month postoperatively. Secondary decompressive curettage and following local radiotherapy were undertaken to cure the disease. Neurological recovery and healing of spinal ABC could be expected if the lining of a cyst had been totally removed. At the 18-month follow-up examination, he was neurologically intact and without any backache, leg pain or gait disturbance.
