Scoliose douloureuse du petit enfant: à propos d'un cas de kyste anévrysmal osseux lombaire (corps de L4 et arc postérieur)

Aneurysmal bone cyst: A rare cause of medullary compression and painful scoliosis in children

“…In our patient, the preoperative MRI indicated an aggressive lesion with little reparative osteogenesis, contiguous vertebral involvement, and infiltration of the surrounding soft tissue. Arteriography can show peripheral hypervascularization, and arteriovenous shunts and can specify the feeder pedicles of the cyst for possible preoperative embolization [8,13]. The scintigraphy shows a primarily peripheral nonspecific uptake in 65% of the cases, also found in unicameral bone cysts, giant-cell tumors, and chondroblastomas [8,13].…”

“…The differential diagnosis must rule out both other benign spine tumors and malignant tumors. In increasing order of frequency, bone tumors in children are eosinophilic granulomas, osteoblastomas, and osteoid osteoma [13]. Microscopically, the composition of the cyst may be dense and cellular; containing plump stromal cells, multinuclear giant cells, and thin-walled blood vessels, or be a preponderantly fibrous tissue with enlarging vascular spaces [4].…”

Vertebrobasilar insufficiency caused by cervical aneurysmal bone cyst – Case report

“…In increasing order of frequency, bone tumors in children are eosinophilic granulomas, osteoblastomas, and osteoid osteoma. 13 Conventional treatment has been directed at the surgical removal of either the entire lesion or as much of it as possible. Recurrence is seen in 10%-44% of cases, with 90% recurring within two years.…”
