Aneurismal bone cyst

E Grecchi, A E Borgonovo, D Re, L Creminelli, F Grecchi
BACKGROUND: Aneurismal bone cysts (ABCs) are benign, non-neoplastic, expansive, and locally destructive lesions that may occur rarely. They are well defined and usually occur in the long bones, pelvis and vertebrae. According to the 2005 World Health Organization (WHO) histological classification of odontogenic tumours, ABC is classified as a bone-related lesion as ossyfing fibroma, fibrous dysplasia, osseous dysplasia, central giant cell lesion (granuloma-CGCL), cherubism and simple bone cyst (SBC)...

The solid variant of aneurismal bone cysts (ABC) is considered rare. It occurs with greater frequency in pediatric patients and in the tibia, femur, pelvis and humerus. We present a case of a metaphyseal lytic lesion on the distal extremity of the radius in a child whose radiograph was requested after low-energy trauma. The hypothesis of a pathological bone fracture secondary to an aneurysmal bone cyst was suggested. After biopsy, the child underwent intralesional excision without bone grafting and the histopathological findings were compatible with the solid variant of aneurysmal bone cyst...

Fibro-osseous benign lesions rarely affect the sinonasal tract and are divided into 3 different entities, namely osteoma, fibrous dysplasia and ossifying fibroma. They share several clinical, radiological and histological similarities, but have different behaviours. Ossifying fibroma, and in particular the "juvenile" histological subtype, may have a locally aggressive evolution and a high risk for recurrence if removal is incomplete. The purpose of the present study is to compare the clinical behaviour of ossifying fibroma with the other benign fibro-osseous lesions; highlight different behaviour between the histological subtypes; compare the advantages, limitations and outcomes of an endoscopic endonasal approach with reports in the literature...

BACKGROUND: Although primary bone tumors are relatively uncommon, they constitute the most important tumors in patients less than 20 years. We aimed to determine the frequencies of primary bone tumors and tumor-like lesions of bone and the anatomical sites of their occurrence. METHODS: A retrospective review of histopathology reports of all bone specimens received in a private pathology laboratory in Istanbul between 2009 and 2015. RESULTS: A total of 57 patients (aged 5 to 18 years) with a mean of 13...

INTRODUCTION: Spinal bone metastases may be lytic or sclerotic lesions. Sometimes aneurismal bone cyst (ABC)-like areas (also called "secondary ABC") can be found in giant-cell tumors, osteoblastomas and chondroblastomas but are rare in metastatic tumors. CASE REPORT: A retrospective study on 518 patients surgically treated for metastatic lesions of the spine from 1995 to 2012 was performed to evaluate the radiographic presentation. We propose a case report of a metastatic lesion associated with imaging features suggestive of aneurismal bone cyst...

Aneurysmal bone cyst is a pseudotumoral lesion. Complete resection prior to selective arterial embolization seems to be the treatment of choice for the more extensive and destructive lesions. In these cases maintaining stability of the cervical spine is critical. This can be very challenging in children and adolescents in whom the axial skeleton is still growing. In this case a young girl presented with a voluminous cervical aneurysmal bone cyst encaging both vertebral arteries and spinal cord. The lesion was treated with aggressive surgical resection, followed by cervical vertebral fusion with instrumentation...

BACKGROUND: Despite the great amount of research concerning bone cysts, there is still no commonly accepted method of treatment. The aim of this study was to evaluate the effectiveness managing bone cyst with hybrid external fixator by distraction osteogenesis. MATERIALS AND METHODS: Between 1982 and 2009, 25 patients with unicameral (20 patients) and aneurismal (five patients) bone cysts were treated using this method. Eighteen patients had a history of pathological fracture at the same location...

Haemorrhagic-aneurismal bone cysts (HABCs) are quite rare, benign, non-neoplastic, expansive, and vascular locally destructive lesions. They are generally considered sequelae of an earlier trauma causing an overflow of blood into the bone. HABCs are classified as pseudocysts and they should be differentiated from true cysts because their treatment is different. Since few of these cysts involve subjective symptoms, most are discovered accidentally during radiography, while a sure diagnosis is likely to be obtained only during surgery, on discovery of a non-epithelialised cavity...

BACKGROUND:  Aneurysmal bone cysts are rare occurrences in the cervical spine. Surgical treatment in pediatric patients is a challenge. Complete tumor resection offers the best chance for cure. DESCRIPTION:  Diagnosis and surgical management of an expansile aneurysmal bone cyst of the cervical spine involving all three spinal columns in a 10-year-old boy. RESULTS:  Surgical treatment included tumor excision and circumferential fusion, and produced no neurological or vascular sequelae...

PURPOSE: The aim of this study was to delineate radiological-pathological correlation in primary vertebral chondrosarcoma. METHODS: Eight histopathologically confirmed cases were analyzed for pathological and radiological characteristics. RESULTS: Magnetic resonance images of three conventional and one clear cell cases showed lobulated or irregular masses with line or septa enhancement. Two conventional lesions showed signal intensity of high water content on T2-weighted images, in which aneurismal bone cysts were confirmed...

Gastrointestinal stromal tumors are a heterogeneous group with a wide spectrum of histologic features. We describe the first case of 61-year-old woman who presented gastrointestinal stromal tumors of the ampulla of Vater with osteoclast-like giant cells surrounding osteoid-like material and aneurismal bone cyst-like areas. The phenotype was supported by light microscopy and corroborated by immunohistochemistry analysis. Because of the presence of osteoid-like and aneurismal bone cyst-like components, it is first necessary to make differential diagnosis with other entities such as metastatic osteosarcoma...

Giant cell tumor is colonized by aneurismal bone cyst in only 15% of cases and cervical localisation accounts for less than 1% of giant cell tumors. We are reporting a rare case of a C2 hypervascularized giant cell tumor colonized by an aneurismal bone cyst treated with an effective preoperative Onyx embolization followed by a full tumor resection. The patient experienced a moderate cervical spine injury 2 months prior admission followed by a progressive stiff neck and cervicalgia. CT and MRI identified a lytic lesion of the body and lateral masses of the C2 with encasement of both vertebral arteries...

Ameloblastoma is a common and aggressive odontogenic epithelial tumor. It has an aggressive behavior and recurrent course, and is rarely metastatic. Ameloblastoma represents 1% of all tumors and cysts that involve the maxillomandibular area and about 10% of the odontogenic tumors. It is primarily seen in adults in the third to fifth decade of life, with equal sex predilection. Radiographically, it appears as an expansile radiolucent, with thinned and perforated cortices, and is known to cause root resorption...

Aneurysmal bone cyst is a pseudotumoral bone dystrophy which accounts for 1.5 to 4% of benign bone tumours. We report the case of a bulky aneurismal cyst of the left superior humeral metaphysis in a seven year old child revealed by a repeated pathologic fracture. Exeresis of the cyst was performed with reconstruction by a non vascularized fibula. After a follow up of one year the patient recovered safely with normal range of motion and anatomically. The cystic exeresis sparing the growth cartilage with fibula graft is indicated in the management of active and aggressive aneurismal cyst of long bones...

Bone metastases are usually seen on imaging studies as lytic lesions and less often as sclerotic or mixed lesions. We report an exceedingly unusual case of breast cancer identified after magnetic resonance imaging showed bone metastases with fluid-fluid levels in the spine and sacrum. Bone images containing fluid-fluid levels are usually solitary abnormalities produced by aneurismal bone cysts. The fluid-fluid level is due to bleeding within the tumor followed by layering of the blood components based on density differences...

Bone tumours and tumour-like lesions of the hip in children are rare. Signs and symptoms of these tumours are generally nonspecific. Delay of diagnosis is not uncommon. A high index of suspicion in young patients presenting with persistent pain and without history of trauma, that is unresolved with conservative therapy should prompt further investigation, including radiographs or computed tomography scan of the pelvis. In the experience of the Istituto Rizzoli, in patients less than 14 years (mean 9 years, ranged from 6 months to 14 years), 752 tumours and tumours-like lesions occurred in the pelvis or proximal femur, involving the hip...

Authors describe two cases of bone lesions ("brown" tumour) secondary to hyperparathyroidism in whom incisional biopsy gave an incorrect diagnosis. The first case was a patient with a lesion of the right femur diagnosed as aneurismal cyst and; the second case was a patient with an isolated lesion of the distal metaphysic of right humerus firstly diagnosed as giant cells tumour. Treatment of the first case was resection and diaphyseal spacer, and the correct diagnosis of brown tumour was performed for the multiple tibial localizations appeared six months later...
