Aneurysmal Bone Cyst of the Proximal Femur and Its Management - A Case Report
Cureus, 2017
Aneurysmal bone cyst (ABC) is a benign, expansile, non-neoplastic lesion of the bone, characterized by channels of blood and spaces that are separated by fibrous septae. Giant ABC is an uncommon condition and can be difficult to handle because of the destructive effect of the cyst on the bones and the compressive effect on the nearby structures, especially in weightbearing bones of the body. We report a case of a giant aneurysmal bone cyst in the proximal femur of a six-year-old child, which was treated with a sclerosing agent and ender's nail fixation first. There was recurrence after 13 months. It was then curetted out extensively, the cavity was filled with bone graft, and fixation with a dynamic hip screw (DHS) was done. At 19 months follow-up, the lesion had subsided and patient was walking pain-free without any deformity. We suggest this method of treatment to be worthwhile for ABC at this site and at this age.
Development of an aneurysmal bone cyst of the femur head in a young patient: A case report
International Journal of Orthopaedics Sciences
We report development of an aneurysmal bone cyst (ABC) that was located in the femur head in an 23year-old male. Over a period of time, the ABC showed local progression, with destruction of the bone, which led to an abrupt loss of function of the left hip. Final decision regarding the therapeutic approach was total hip arthroplasty with femoral reconstruction with a prosthesis. Following this treatment, the patient's outcome was favourable, with complete recovery of function.
Aneurysmal bone cyst in the proximal femur: Combined approach of management: a case report
2021
Purpose of Study: To study the effectiveness of combined extended curettage and sclerosant therapy in the management of aneurysmal bone cyst of proximal femur. Materials and Methods: A 22 years old male presented with complaints of left hip pain since 20 days, was examined clinically and radiologically. On MRI, he was diagnosed to have a non-expansile lytic lesion in the left proximal femur with features suggestive of aneurysmal bone cyst or an unicameral bone cyst. Patient was planned and taken up for aspiration and curettage followed by a single sitting sclerosant therapy with 3% polidocanol, bone cementing combined with plating. Curetted sample was sent for histo-pathological examination. Patient was advised restricted weight bearing for a period of 4 weeks. Regular follow-ups of the patient was done at 1, 3, 12 and 18 months post-operatively to assess for recurrence. Results: Histo-pathological examination confirmed the diagnosis of aneurysmal bone cyst. With regular follow-ups,...
Bilateral Primary Aneurysmal Bone Cyst of Proximal Femur: A Rare Case Report
Case Reports in Orthopedic Research
Aneurysmal bone cysts (ABC) are blood-filled, locally destructive, expansile lesions of the bone. ABC of the proximal femur is usually unilateral in presentation. As far as the English literature is concerned, there is no case report of bilateral involvement of the proximal femur by primary ABC. We hereby present a rare case of bilateral primary ABC of the proximal femur with pathological fracture of the right femoral neck. The patient underwent right hip hemiarthroplasty and open biopsy and curettage of the left proximal femur. ABC is usually unilateral in location. Whenever there is a bilateral lesion in the proximal femur usually ABC is not suspected as a differential diagnosis, but ABC may have a bilateral presentation.
Challenges in the Diagnosis and Treatment of Aneurysmal Bone Cyst in Patients with Unusual Features
Advances in Orthopedics, 2019
Objectives. Aneurysmal bone cyst (ABC) is a benign but locally aggressive tumor. It has several challenging features. The aim of this study is to identify challenges in the diagnosis and treatment of ABC especially in patients with unusual features. Methods. This retrospective study involved medical record review of primary ABC patients with one or more of the following features: unusual clinical presentation with a mass or a pathological fracture especially at an unusual age, rare locations, radiological findings suggesting other diagnoses especially sarcoma, and a nondiagnostic histopathology of biopsy samples. Results. 25 patients (17 males and 8 females) were included. Most patients were either younger than 10 or older than 20 years. 10 patients presented with a mass or a pathological fracture. Unusual locations include the scapula, the olecranon, the hamate, the calcaneus, and the first metatarsal bone. Extension into the epiphysis occurred in 2 patients with proximal fibula an...
Extraosseous aneurysmal bone cyst in a 12-year-old girl
Pediatric Radiology, 2005
A soft-tissue aneurysmal bone cyst located on the lateral aspect of the left thigh of a 12-year-old girl is described. Conventional radiography of the thigh was normal. Sonography showed a hypoechoic mass with a feeding vessel and intralesional vascularity. On MRI, it was of predominantly soft-tissue signal intensity with intense enhancement following administration of IV contrast medium. Histopathological examination diagnosed the lesion as a soft-tissue aneurysmal bone cyst. This is the fourth paediatric case of this very rare benign tumour.
Aneurysmal bone cyst of the pelvis and extremities: Contemporary management
International Journal of Surgery Oncology, 2019
Aneurysmal bone cysts are tumors of bone occurring predominantly in the metaphyses of long bones and posterior elements of spine in adolescents and young adults. Radiographically, on x-rays they appear as eccentric metaphyseal expansile lytic lesions containing “fluid-fluid” levels. Computed tomographic scan and magnetic resonance imaging clearly define the cysts and fluid-fluid levels; the former delineates cortical expansion and the latter the fibrovascular component clearly. Magnetic resonance imaging is particularly useful in differentiating aneurysmal bone cysts from malignant lesions. Histologically, these cysts are characterized by fibrovascular tissue, multinucleated giant cells, inflammatory cells, fiber-osteoid, “blue bone,” and blood filled lacunae. Chromosomal translocation has been found, implying a neoplastic basis for the development of aneurysmal bone cysts. Malignant transformation has been reported where radiation therapy was used, and in cysts associated with sarc...

Aneurysmal bone cysts are enigmatic, locally destructive, blood filled lesions of bone with unknown cause and unusual presentations. We report a case of 16 year old female with aggressive aneurysmal bone cyst of proximal left femur complicated by transcervical fracture neck of femur. As the age of the patient was not suitable for replacement, a successful attempt was made to salvage the hip with intralesional curettage and fixation with 2 fibular struts and a cancellous hip screw. Femoral head is viable till date.
Epidemiology of aneurysmal bone cyst in children: a multicenter study and literature review
Journal of Pediatric Orthopaedics B, 2004
The purpose of this study was to review the demographic data of children and adolescents with aneurysmal bone cysts (ABCs). The authors performed a retrospective, multicenter, pediatric population-based analysis of 156 patients with primary ABCs. Only patients with histologic confirmation of the diagnosis were included. A review of French and English literature of 255 children and adolescents was included regarding sex, location of the lesion and age at diagnosis. There were 212 boys and 199 girls with a median age at diagnosis of 10.2 years (range, 1.5-17 years). Forty-four patients were under 5 years of age; 111 patients were between 5 and 10 years of age, and 139 were older than 10 years of age. The femur, tibia, spine, humerus, pelvis and fibula were the most common locations. In 256 cases (62.7%), ABCs occurred in long bones. We also studied the data and location of 161 ABCs of the mobile spine (13 cases from our series and 148 from the literature review). There were 48 ABCs in the cervical spine, 48 in the thoracic spine, and 65 in the lumbar spine. We found no main differences in site distribution and sex, between the children and the general population.
