A case of traumatic bone cyst has been presented that illustrates the less common findings of cortical expansion, inferior alveolar paresthesia, and multiplicity of lesions. A brief review of the literature is also presented.
Local injection of radiopaque medium demonstrated the presence of intracystic fibrous septa in 13 patients with solitary bone cyst. Contrast examination was helpful in predicting the response of solitary bone cysts to treatment by injection of methylprednisolone-acetate (MPA). As the number of septa increased, an increased difficulty in obtaining an equal distribution of MPA inside the cyst and a higher incidence of incomplete healing of the cyst was encountered.
An 8-year-old boy sustained a fracture of the distal fibula. The fracture resulted from Ewing's sarcoma infiltrating a unicameral bone cyst. Ewing's sarcoma has not previously been described in association with a unicameral bone cyst.
Patient age plays a significant role in the presentation and clinical behavior of bone cysts. In children, cysts behave more aggressively than in adults and the recurrence rate for patients in the first decade of life is four times that in the adolescent. Simple bone cysts are less frequent after 17 years of age and 80% of cysts in the young are located in the proximal end of the shaft of the humerus and femur. Pathological fractures will call attention to the cyst and the highest incidence of fractures is in childhood (0--10 years).
The aetiology, clinical and radiographic features and the treatment of simple bone cysts of the jaws are discussed. Recurrence of jaw lesions is unusual. Two cases are presented of simple bone cyst in the mandible which recurred following conventional treatment. The importance of clinical and radiographic follow-up is emphasised.
Dislocation osteotomy with subpositioning of the distal fragment - without additional implantation of bone material (!) - yields excellent results in the treatment of large juvenile bone cysts of the coxal end of the femur (Imhäuser), as confirmed by the author's own experience. The advantages of this procedure compared with other methods are described. Taking into consideration the two cases successfully treated by Imhäuser at the shaft of the upper arm in the same manner, it is demonstrated by describing the case of a patient with extended juvenile bone cyst in the region of the proximal humerus that here, too, dislocation osteotomy leads to complete cure within a short time, so that its increasing use appears justified.

Cystic or solid lesions of ribs containing giant cells are rarely seen in children. Three cases are presented which are uncommon with regard to the age of the patients (5-14 yr old) as well as the site. These lesions were diagnosed late and exclusively by X-ray. Radiographically it was impossible to distinguish between a giant cell tumor and an aneurysmal bone cyst. Although the distinction of aneurysmal bone cysts and giant cell tumors sensu strictiori is justified from a clinical point of view, the two may be variants of the same pathologic growth process, i.e. growth of angiogribous tissue with giant cells in excess of that generally observed in the course of a "reactive" process.
Twenty-one patients were treated operatively for unicameral bone cysts by subtotal resection without any form of bone graft, and all but two patients had satisfactory, prompt healing. The rate of recurrence was 9%. Five patients were noted to have humeral shortening prior to any surgery, and in them the changes in the epiphyseal cartilage were noted preoperatively. Pathological fractures were thought to be the cause of the shortening in those cases.
Four cases of aneurysmal bone cysts of the spine are described. Problems of nomenclature, pathogenesis, and treatment are discussed with reference to the literature. Complete excision is the treatment of choice whenever possible. However, subtotal excision and adequate spinal decompression followed by radiotherapy provide satisfactory results.
The trabecular bone cyst (TBC) is the jaws' equivalent of the unicameral cyst of the long bones. A series of 20 TBCs were surgically treated in the jaws (19 in the mandible and one in the maxilla) of 14 Chinese patients (five males and nine females), who could broadly be divided into two age-sex groups; a young group of both sexes and an older, exclusively female group. Three patients in the older group had more than one TBC and the one with initially five separate TBCs (including one in the maxilla) exhibited six episodes of recurrence of the mandibular lesions which finally coalesced to affect the whole body of the mandible bilaterally.
Fibrous dysplasia (FD) is a rare tumour, representing 2.5% of all bone tumours and 7% of benign tumours. Aneurysmal bone cyst (ABC) is also an uncommon pathology, usually associated with a secondary vascular lesion consisting of an arteriovenous malformation. In this article, we relate a case report of a young female with a rare combination of FD with aneurysmal bone cyst presenting as a subarachnoid haemorrhage (SAH). Despite the possibility of clinical treatment of these lesions, this report demonstrates that symptomatic lesions may be successfully managed by surgical resection. The authors' opinion is that this treatment should be individualised depending on particularities of each case, such as localisation of the lesion, biopsy results and image exams features. We also present a critical literature review of diagnostic methods and therapeutical options for both ABC and FD, with emphasis on controversial topics surrounding these issues.
Ten cases of solitary bone cyst are presented. Nine of the lesions were asymptomatic and were discovered incidentally. Two patients were operated upon while eight were followed for 1 to 14 years. In spite of severe foot injuries that three patients have sustained, no fracture of the calcaneus occurred. We also showed experimentally that the strength of the calcaneus is not significantly reduced by the presence of the cyst. Therefore operative intervention in this lesion is not recommended. Acknowledgements: We wish to thank Dr. M. Carakostas, Consultant Orthopaedic Surgeon at Asclepeion Hospital, Athens, for allowing us to present Case 6 and Mr. St. Paipetis, Professor of the Polytechnic School of Athens, for his adivce during the experimental work.
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 bone cysts are discussed.
Two cases of aneurysmal bone cyst of the spine are reported. These rather rare tumours may pose initial diagnostic problems. If, however, the clinical and radiological features are studied, diagnosis should be easy and the appropriate treatment will follow. Computed tomography provides an additional diagnostic aid. Management appears to be primarily surgical, but the role of radiotherapy has not yet been clearly defined.
Two cases of aneurysmal bone cyst are recorded. In the first there is clinical evidence to suggest that the lesion had been present for an unusually long period while incomplete clinical records of the other also indicate an unusual history. Histologically both lesions show a paucity of giant cells. It is not possible to make significant observations on aetiology other than support the theory that the lesion arises as a result of altered haemodynamics.
80-90% of individuals suffering from aneurysmal bone cyst (ABC) are children or adolescents. Primary ABC is a non-neoplastic lesion. Diagnostic assessment and detection of recurrence demands repeated plain x-rays or CT scans. These repeated radiographic examinations expose these young patients to large doses of ionizing radiation. Magnetic resonance imaging (MRI) is found to be an effective and reliable noninvasive technique for the diagnosis and follow-up controls of ABC.
Whereas curettage and bone grafting of aneurysmal bone cysts (ABC) are generally accepted, recurrence is not uncommon and surgery is hazardous when the lesion is large and adjacent to the growth plate. High-energy, low-dose radiation in an eight-year-old girl with this lesion of the distal tibia was successful with no recurrence at the three-year follow-up examination. No complications have ensued, and excellent function has been sustained. Further evaluation of this form of radiation treatment is important in similar situations in which surgical excision of ABC may carry high risks.
