Treatment of Enneking Stage 3 Aggressive Vertebral Hemangiomas With Intralesional Spondylectomy Report of 10 Cases and Review of the Literature
ABSTRACT A retrospective review of consecutive series of Enneking stage 3 vertebral hemangiomas surgically treated at a major tertiary spine tumor center.
To determine the short-term recurrence rates, pain improvement, and operative morbidity of intralesional spondylectomy combined with preoperative embolization for Enneking stage 3 vertebral hemangiomas.
Aggressive vertebral hemangiomas (Enneking stage 3) often involve both the anterior and posterior columns with spinal canal and local soft tissue extension and may present with dramatic bony destruction, spinal instability, and pain accompanied with neurologic compromise. Although the current treatment paradigm for most vertebral hemangiomas is conservative management directed toward symptomatic relief, the subset of patients presenting with this rare variant requires more extensive surgical treatment.
A retrospective clinical review of patients diagnosed with Enneking stage 3 vertebral hemangiomas was conducted at the University of California at San Francisco.
We identified 10 consecutive cases of Enneking stage 3 hemangiomas. Average follow-up was 2.42 years. The most common presentation was pain with or without myelopathy. Three of the 10 cases were recurrences after prior partial resection and reconstruction or cement augmentation. All patients underwent preoperative embolization. Average blood loss despite embolization was 2.1 L (range: 0.8 to 5 L). Average preoperative back pain visual analog scale was 7.2 and postoperative visual analog scale was 3.1 at 6 months. On postoperative imaging, all patients had gross total resection. Six patients had staged posterior/anterior transcavitary approach and 4 patients underwent single stage posterior transpedicular spondylectomy. To date, no patient has required adjuvant radiation therapy for tumor recurrence.
Our results suggest that complete wide resection of aggressive Enneking stage 3 lesions can be safely accomplished with acceptable morbidity and blood loss and significant improvement in pain and neurological status. Partial resection of stage 3 lesions, even with stabilization or vertebroplasty, may lead to early recurrence.

ABSTRACT: Vertebral hemangioma (VH) is virtually vascular malformation, which is usually asymptomatic. Only 3.7 % of VH may become active and symptomatic, and 1 % may invade the spinal canal and/or paravertebral space. Treatment protocols for active or aggressive VHs are still in controversy. Reported treatments include radiotherapy, vertebroplasty, direct alcohol injection, embolization, surgery and a combination of these modalities. A 41-year-old lady was presented with 18 month history of intermittent back pain. CT revealed T5 osteolytic lesion with epidural and paravertebral extension. The first CT guided biopsy yielded little information. Histopathological diagnosis of the second biopsy was VH. Vertebroplasty, posterior decompression and fixation were performed followed by postoperative radiotherapy. Her symptoms were resolved immediately after the operation. At 12 months follow-up, no recurrence was detected by CT with contrast enhancement. Surgical decompression, vertebroplasty and fixation are safe and effective for aggressive VH. More attention is needed in determining the algorithm for the diagnosis and treatment of aggressive VH.European Spine Journal 06/2012; 21(10):1994-9.

ABSTRACT: Vertebral hemangiomas (VHs) are called benign tumors but are actually just vascular malformations. The diagnosis and treatment for aggressive VHs is still controversial, due to their rarity. To evaluate the safety and efficiency of the present diagnostic methods and treatment choices. A retrospective study of aggressive VHs with neurologic deficit. A total of 29 consecutive aggressive VH cases were diagnosed and treated in our department since 2001. We routinely took anteroposterior and lateral spinal roentgenograms, computed tomography, and magnetic resonance images. Trocar biopsy is indicated in suspected malignant cases. Radiotherapy was usually our first choice if the neurologic deficit was mild or developed slowly. Surgery was indicated if the neurologic deficit was severe or developed quickly or if the radiotherapy was not effective. This series included 12 males and 17 females, and the mean age at diagnosis was 44.0 years (range, 21-72 years). Ten patients had radiculopathy, 1 had cauda equina syndrome, and 18 cases had myelopathy. Twenty-one cases had lesions in the thoracic spine, 5 in the lumbar, and 3 in the cervical region. Eleven cases had untypical image findings, including five cases with pathologic vertebral fracture. The neurologic compression came from only epidural soft tumor mass in 18 cases, whereas it came from both bony compression and soft lesion in the other 11 cases. Ten cases had radiotherapy alone, but two failed and had surgery later. Twenty-one cases had surgery. In the 12 cases having surgical decompression without vertebroplasty, the average estimated blood loss was 1900 mL, and it was 1093 mL for the eight cases having decompression with vertebroplasty. The average follow-up was 51.1 months (range, 24-133 months). There was no recurrence in those cases with radiotherapy, whereas three had local recurrence in those six cases treated by surgical decompression alone without radiotherapy. In aggressive VHs, epidural soft-tissue compression was usually the main reason for neurologic deficit. In cases with rapid progressive and/or severe myelopathy, posterior decompression and stabilization could be combined with intraoperative vertebroplasty to reduce blood loss.The spine journal: official journal of the North American Spine Society 10/2013; 14(6).
