The incidence of aneurysmal bone cysts is 0.14 cases per 100,000 individuals. Parosteal aneurysmal bone cysts are the least prevalent subtype and represent 7% of all aneurysmal bone cysts. We present the case of a 38-year-old male patient with pain and bulging in his right arm for eight months. He had previously been diagnosed as presenting giant-cell tumor, but his slides were reviewed and his...

Aneurysmal bone cysts are uncommon lesions, especially in the ribs. Four patients with aneurysmal bone cysts of the rib are presented and previously reported cases reviewed. A brief discussion of the clinical manifestations, pathology, aetiology, and current treatment of aneurysmal bone cyst is also included.

Although aneurysmal bone cysts and calcifying odontogenic cysts accompanied with other lesions are reported in the literature, the simultaneous occurrence of these two distinct lesions has not been reported. To the best of our knowledge, this is the first report describing co-occurrence of these two lesions located in the left mandibular ramusin a 36-year-old woman.      

To present a rare case of a cystic giant schwannoma of the sacrum mimicking aneurysmal bone cyst (ABC). A 54-year-old man visited our institute complaining left leg weakness and sensory change for several years. Magnetic resonance imaging revealed a large multilocular cystic mass with canal invasion and bone erosion confined to left S1 body. The lesion showed multiple septal enhancement without...

INTRODUCTION Aneurysmal bone cysts are benign tumours that usually present in childhood. Aggressive forms have been described, which are often treated with surgery that entails major resection and reconstruction. Polidocanol sclerotherapy has recently been reported to have excellent results and promises to replace operative treatments, but its efficacy in the case of aggressive aneurysmal bone ...

INTRODUCTION Aneurysmal Bone cysts (ABC) are extremely rare in the head and neck region and even rarer in sinuses. ABC is a benign multicystic mass that is locally-destructive and rapidly expandable. Hemorrhagic fluid content (like in this case) and septated appearance are the characteristic feature of ABC. Established treatment options for ABCs include sclerotherapy, embolization, radiotherapy...

Surgically accessible aneurysmal bone cysts (ABC) have traditionally been treated with curettage. Selective arterial embolization was initially proposed as a preoperative adjuvant to reduce peroperative bleeding. Currently, the role of embolization has been extended to the definitive treatment of aneurysmal bone cyst of the spine in children, as well as to other locations in the skeleton. The a...

   Aneurysmal bone cyst (ABC) is a benign expansile bone tumor, most commonly involving the medulla of long bones. ABC rarely arises within the cortex or in the subperiosteal region, radiographically mimicking other conditions, in particular surface osteosarcomathat is low-grade in nature and may go secondary ABC changes, and telangiectatic osteosarcoma. Both of these are sometimes mistaken mic...

Aneurysmal bone cysts (ABCs) are expansile cystic lesions that can affect any bone of the body. Whilst these lesions are histologically benign, the lesions are locally aggressive and can affect the integrity of the affected bone as well as surrounding structures. ABCs arising in the head and neck region, particularly the paranasal sinuses are rare and they are limited to case reports in the lit...

We report three cases of spontaneous healing of aneurysmal bone cysts (ABC). In one case histological material was obtained after resection of the already ossified expansile mass discovered as a lytic lesion seven months previously. In the two other patients, spontaneous ossification of a radiologically presumed ABC in the lytic and expansile phase was observed after nine and seven months respe...
