Occipital aneurysmal bone cyst: CT features

A case of aneurysmal bone cyst arising from the lower occipital squama with intracranial extension is presented. The case is unique in that the cyst showed fluid levels on CT. Another peculiarity of this case was postoperative recurrence.     

Chondroblastoma of the patella with a secondary aneurysmal bone cyst

A case of chondroblastoma of the patella combined with an aneurysmal bone cyst is presented. Chondroblastoma of the patella is an uncommon, benign neoplasm. On the other hand, secondary aneurysmal bone cyst is frequently associated with giant cell tumour of chondroblastoma.

Intracranial aneurysmal bone cyst: a rare CT appearace

Summary Aneurysmal bone cyst occurring within the calvarium is uncommon. We report a case presenting as an intracranial space-occupying lesion. Fluid levels within a lesion on CT is very suggestive but inconstant. The theory of a pre-existing lesion is noted.     

Giant aneurysmal bone cyst of the scapula: A case report

Aneurysmal bone cyst (ABC) is a benign bone tumor affecting mainly children and young adults. It occurs in the metaphysis of the long bones. The scapula is a very rare location. Imaging may be highly suggestive of ABC in cases of an osteolytic, expansive, and hemorrhagic lesion with fluid-fluid levels and thin septa. The diagnosis must systematically be confirmed by performing a biopsy, in order to adopt the best therapeutic strategy. There are several therapeutic means, but wide resection remains the gold standard. The evolution is very variable and can go from spontaneous healing to recurrence with the destruction of the bone. We report a rare case of aneurysmal bone cyst of the scapula in a young patient.     

原发性与继发性动脉瘤样骨囊肿CT表现

目的评价CT对诊断与鉴别原发性与继发性动脉瘤样骨囊肿的价值。方法回顾性分析9例经手术病理证实原发性与继发性动脉瘤样骨囊肿的CT征象,并进行献复习。结果9例患中骨皮质缺损征象出现率(67％)高于“液一液平面”出现率(44％)。继发性动脉瘤样骨囊肿骨嵴明显粗大,可构成分房。9例病灶内呈不均匀软组织密度,增强后强化明显。结论CT检查有助于动脉瘤样骨囊肿早期定性诊断,并有助于鉴别原发性与继发性病灶。     

A rare case of sino-nasal aneurysmal bone cyst

Aneurysmal bone cysts (ABC) are rare in the paranasal sinuses. They are benign expansile multicystic masses containing blood-filled spaces which typically occur in the long bones of pediatric patients. The lesion often produces symptoms due to the compression of adjacent structures or pathological fracture and depends on localization. In this case report, we discuss a 28-year-old female who presented with left-sided headache, left eye proptosis, and diplopia. Radiologic evaluation revealed a left paranasal sinus expansile multicystic mass with internal blood fluid levels displacing and thinning the left medial orbital wall which suggested the diagnosis of ABC. Radiologists should be familiar with and comfortable diagnosing ABC in the head and neck, and be able to differentiate this entity from others, such as telangiectatic osteosarcoma. Biopsy can be challenging since blood products may be the only material identified and may produce tissue that is difficult to interpret or misdiagnosed.     

Juxtaepiphyseal aneurysmal bone cyst

Nine cases of aneurysmal bone cyst arising in juxtaepiphyseal locations with gross invasion of the adjacent growth plate are reported. In five of these patients an abnormality of growth, due to premature fusion of the affected growth plate, ultimately developed. Treatment of these lesions should attempt to avoid this complication, which appears to be more common than has been appeaciated in the past. These nine cases represent 23% of 39 cases of aneurysmal bone cyst occurring in a long bone adjacent to an open epiphyseal plate. This series was extrapolated from a total of 198 cases of aneurysmal bone cyst in the files of the Istituto Ortopedico Rizzoli, Bologna, Italy.
