[Pediatric neurosurgical treatment of aneurysmal bone cyst at the level of thoracic spine].

<p style="text-align: justify;">Aneurysmal bone cysts are benign but locally&nbsp;aggressive bone tumours, most often&nbsp;affecting children and young adults. In this&nbsp;case report, we present the clinical&nbsp; picture of a 15-year-old boy with progressive, chronic&nbsp;back pain. An MRI of thoracic spine&nbsp; confirmed a T2 cystic spinal tumour. After considering&nbsp;potential options surgical removal&nbsp;was our&nbsp;choice and gross total removal&nbsp;was achieved&nbsp;with T1-3 short-segment fixation.&nbsp;Aneurysmal&nbsp;bone cysts are often rapidly&nbsp;expanding&nbsp;lesions with vascular&nbsp; transformation. In order&nbsp;to avoid irreversible damage, in addition to&nbsp;early diagnosis, it is necessary&nbsp;to carefully&nbsp;consider the therapeutic&nbsp;options, perform&nbsp;surgical removal and stabilization as necessary.&nbsp;In case of the presented patient,&nbsp;extensive&nbsp;surgical removal&nbsp;and short-segmentation&nbsp;were performed.&nbsp;At 18 months&nbsp;of follow-up, he had no complaints and was&nbsp;asymptomatic.&nbsp;Follow-up imaging studies&nbsp;showed no residual or recurrent tumour to&nbsp;date.
