Popis: Vertebral hemangiomas are benign, highly vascular spinal lesions that are extremely rare in the pediatric population. We report a pediatric case of symptomatic vertebral hemangioma treated with total en bloc spondylectomy. Our objective is to demonstrate that en bloc spondylectomy is feasible and addresses some pitfalls of traditional total tumor resection. Our patient presented with bilateral lower limb and perineal paresthesia, paraparesis, as well as urinary retention. Locally aggressive vertebral hemangioma was the presumed diagnosis following imaging. The patient received partial angioembolization to reduce the vascularization of the lesion then underwent total en bloc spondylectomy of T8 under intraoperative neuromonitoring. The intervention was well tolerated. Postoperative course was marked by clinical improvement and only transient, treatable complications. On 1-year follow-up, the patient is neurologically intact, and imaging reveals adequate position of hardware, good alignment, and no tumor recurrence. Total en bloc spondylectomy is a feasible procedure in pediatric patients. It reduces local recurrence through reduction of tumor cell contamination and residual tumor and thus may avoid postoperative radiotherapy in select cases. It may also enhance functional neurological recovery by allowing circumferential decompression and increased spinal cord blood flow.
