Aneurysmal bone cyst
on the carpus of an African collared dove (Streptopelia roseogrisea).
Radiograph shows lesion in posterior element of spine with differential diagnosis including aneurysmal bone cyst
and osteoid osteoma.10 Classically, it represents central nidus with a surrounding radiolucency and reactive sclerosis.
In this paper, a case with I-131 accumulation due to a benign bone cyst
in the clavicle is also included, who has been previously reported (4).
The differential diagnosis of cemento-osseous dysplasia (COD) may include several possible entities, which must consider the stage of a lesion's development and the possible co-existence with associated entities like diffuse osteomyelitis or simple bone cyst
. Consequently, there have been many reports of misdiagnoses and mismanagement of COD cases.
The most common pediatric benign bone tumors include nonossifying fibroma (NOF), osteochondroma, Langerhans cell histiocytosis (LCH), unicameral bone cyst
(UBC), aneurysmal bone cyst
(ABC), and osteoid osteoma.
Based on the patient's age and imaging features, differential diagnosis raised were those of a non-aggressive bone tumor, such as fibrous dysplasia, giant cell tumor, and aneurysmal bone cyst
. The patient underwent open surgery involving open biopsy and curettage, followed by bone grafting.
Pathological types of tumors: nine cases of aneurysmal bone cyst
, 11 cases of simple bone cyst
, eight cases of bone fibrous dysplasia, nine cases of enchondroma, three cases of non-ossifying fibroma and two cases of eosinophilic granuloma.
Major criteria Minor criteria More than two basal cell Congenital skeletal anomaly: carcinomas, or BCCs; one BCC at bifid, fused, splayed or missing younger than 30 years of age; or rib or bifid, wedged or fused more than 10 basal cell nevi vertebra Any odontogenic keratocyst Occipital-frontal circumference, (proven on histology) or more than 97 percentile, with polyostotic bone cyst

The term "aneurysmal bone cyst
" was first coined in 1942 by Dr.
In the present work, we would like to demonstrate an interesting case of a giant solitary bone cyst
of the lateral condyle at the site of knee osteoarthritis, which was successfully treated by cyst curettage, filling with a synthetic resorbable bone graft substitute, and primary, cruciate-retaining total knee arthroplasty.
