Abstract

We describe a comprehensive, multidisciplinary treatment approach for lumbar vertebral hemangiomas (VHs) with spinal stenosis and radiculopathy. A 59-year-old female presented with 1 year of pain predominantly in the lower back, with pain in the left buttock and proximal left anterior thigh as well and magnetic resonance imaging of the lumbar spine demonstrated lumbar scoliosis and an L3 vertebral lesion suspicious for hemangioma. A computed tomography guided biopsy was done, which supported the diagnosis. Definitive treatment entailed preoperative angiography and embolization, followed by L3 laminectomy, right L3 pedicle resection, partial L3 corpectomy, L3 vertebral cement augmentation, and L1 to L5 instrumented fusion. By 1-year postoperatively, the patient reported no radicular pain and only mild groin pain attributed to left hip degenerative joint disease. Radiographs 1-year postoperatively confirmed the stability of the instrumented posterior fusion and a magnetic resonance imaging with and without contrast confirmed no VH recurrence. A comprehensive and multidisciplinary approach for the treatment of VHs with neurological symptoms or signs is presented. This approach is recommended to maximize lesion removal, ensure biomechanical stability, and minimize recurrence.

 Introduction



Vertebral hemangiomas (VHs) are benign neoplasms of endothelial origin that penetrate and may remodel surrounding bony trabeculae.[1],[2] These lesions have an estimated incidence of 11% in the adult population and are commonly found in the vertebral bodies of the thoracic and lumbar spine.[1],[2],[3],[4] The large majority of these lesions are asymptomatic and discovered incidentally by imaging, whereas a minority of them may become symptomatic and lead to back pain, radiculopathy, and myelopathy.[1] The imaging appearance of aggressive VHs (lesions that cause compression of neural elements) in radiographs may exhibit vertebral collapse and pedicle erosion.[1] Using advanced imaging techniques, other features of aggressive VHs may be seen: a “polka dot” appearance, due to reinforced trabeculae, in computed tomography (CT) axial sequences and low signal on T1 sequences and high signal on T2 sequences, due to increased vascularity, in magnetic resonance imaging (MRI) sequences.[1],[5]

A number of treatments have been proposed for symptomatic VHs, including radiotherapy, orthosis (when a threatened pathological fracture is present), ethanol injection, embolization of the lesion's vascular supply, vertebroplasty, kyphoplasty, or a combination of these techniques when pain or mild neurologic deficits were present.[6] The recommended treatment for more significant neurologic issues, such as radiculopathy, myelopathy, or cauda equina syndrome, is surgery.[6],[7],[8] The posterior surgical approach is commonly used unless the VH is restricted to a ventral location (which is more amenable to an anterior approach) or is suspected to be malignant (thereby necessitating wide resection with techniques such as spondylectomy).[6]

Due to the rarity of these lesions and treatment descriptions limited to small case series, no broad consensus exists regarding the optimal treatment of VHs. In this manuscript, we present the case of a patient with central and foraminal stenosis with resultant left L3 radiculopathy caused by an L3 VH. A multidisciplinary approach with a spine surgeon and musculoskeletal oncologist was used to appropriately characterize the L3 VH and treat with preoperative embolization, L3 laminectomy, intraoperative biopsy, lesion resection, vertebroplasty, and L1–L5 instrumented posterior spinal fusion. This led to pain resolution, no recurrence of the hemangioma lesion, and stable hardware positioning 1-year postoperatively. The patient consented to the publication of details of her case.

 Case Report



Initial presentation

The patient was a 59-year-old female seen by a spine surgeon for 1 year of low back pain, with radiation down the left buttock to the left proximal anterior thigh. At the time of the initial evaluation, she stated that her pain was 10/10 at times on the Visual Analog Scale (VAS). She had trialed conservative treatments to manage her pain, including over-the-counter analgesics, neuromodulators, and physical therapy. She denied urinary/bowel incontinence, perineal anesthesia, and numbness or paresis in the left lower extremity. The patient's neurological examination revealed no motor or sensory deficits or upper motor neuron findings in the bilateral lower extremities.

Preoperative anteroposterior and lateral radiographs, as well as computed tomography (CT) and magnetic resonance imaging (MRI), were obtained of the lumbar spine [Figure 1] and [Figure 2]. These demonstrated a lesion in the L3 vertebral body with a “honeycomb” trabecular matrix pattern that was well-vascularized, encroaching posteriorly into the epidural space, and causing severe thecal sac and left L3 nerve root compression.{Figure 1}{Figure 2}

Although these findings strongly suggested aggressive VH, other diagnostic possibilities included malignancies such as metastases, multiple myeloma, lymphoma, chordoma, and epithelioid hemangioendothelioma.[1] Due to the above considerations, the patient had a consultation with a musculoskeletal oncologist before operative intervention. Afterward, she was referred to our Interventional Radiology colleagues for a transpedicular CT-guided biopsy to obtain a histopathological diagnosis. The pathological examination did not reveal any evidence of malignancy and was highly suggestive of a hemangioma.

Treatment and postoperative course

Definitive treatment began with an angiogram of the bilateral L1 to L3 radicular arteries, followed by successful embolization of the L3 branches the day before the surgery. Surgical treatment commenced with an L3 laminectomy and open biopsy of the lesion. Once the biopsy confirmed VH, right L3 pedicle resection and partial L3 corpectomy were done for neural decompression. This was followed by L3 vertebroplasty under fluoroscopic visualization and L1-L5 instrumented posterior spinal fusion [Figure 3].{Figure 3}

The patient experienced no immediate intraoperative or postoperative complications and total estimated blood loss was approximately 1500 mL. On the day of discharge (4 days postoperatively), she reported 6/10 pain on the VAS and standing radiographs demonstrated good hardware position and no L3 collapse or cement extrusion [Figure 4]a and [Figure 4]b. At the patient's routine 6-week and 3-month postoperative visits, she reported that her radicular pain was significantly improved compared to her preoperative baseline and repeat radiographs were stable. By 1-year postoperatively, the patient reported no radicular pain and only mild groin pain attributed to left hip degenerative joint disease. Radiographs 1-year postoperatively [Figure 4]c and [Figure 4]d. confirmed the stability of the instrumented posterior fusion and an MRI with and without contrast confirmed no VH recurrence.{Figure 4}

 Discussion



When determining treatment for a VH, it is important to consider whether it is asymptomatic or not, the location and extent of its effect on osseous structures, and which neural elements are affected by the lesion. A VH that is symptomatic with focal neurologic complaints or exam findings, in conjunction with imaging demonstrating a metabolically active tumor with compression of neural elements, is consistent with an aggressive VH that is indicated for surgery.[1],[6] The posterior location of the VH, the extent of its expansion, and its compression on neural elements precluded anterior only and posterior decompression alone surgical approaches for this patient. A posterior approach with decompression, intralesional resection, and instrumented fusion, complemented by preoperative embolization and cement augmentation, was our preferred technique and this has been used successfully to treat noncontiguous VHs.[9] A marginal or wide resection for VH alone, particularly a spondylectomy, was not necessary for recurrence control based on a multicenter study by Goldstein et al.[10] Since aggressive VHs may be difficult to distinguish from malignancy, we recommend routine involvement of a musculoskeletal oncologist and preparation for wider-than-initially-anticipated resection using oncologic principles (which has shown acceptable morbidity and satisfactory survival).[11]

Benefits of our approach, for our patient's case, are its combination of angiography and embolization of the VH the day before the surgery, combined with laminectomy, open biopsy, intralesional resection, limited vertebroplasty under fluoroscopic guidance, and a long construct posterior spinal instrumented fusion. Preoperative angiography and embolization aids in reducing intraoperative blood loss and associated morbidity.[9],[12] A wide decompression to grossly inspect the neoplasm, with open biopsy by the musculoskeletal oncologist, then permits definitive histopathological confirmation that the VH is not a malignancy (which could have mandated a wide resection). Intralesional resection with limited vertebroplasty under fluoroscopic guidance then aids in local tumor control, reducing recurrence, and imparting additional mechanical support. Finally, we choose a long construct for posterior spinal instrumented fusion (2 levels above and below the VH). This decision was due to the lesional resection mimicking the structural deficiencies of an unstable three-column thoracolumbar fracture, shown by biomechanical studies to be well stabilized by long constructs.[13]

Future considerations could include cement-directing kyphoplasty (instead of vertebroplasty) to achieve more void augmentation and decrease the risk of cement extravasation. More detailed pain and function assessments of patients postoperatively could help assess the success of our proposed treatment approach and improve surveillance for potential VH recurrences.

In conclusion, this case report describes a novel multidisciplinary collaboration between a spine surgeon, musculoskeletal oncologist, and other providers allowing for comprehensive diagnosis and treatment of an aggressive VH with epidural extension and focal neurologic findings. Our recommended treatment for this VH is preoperative angiography and embolization, decompression with laminectomy, open biopsy, partial corpectomy/debulking with vertebroplasty, instrumented posterior spinal fusion with a long segment construct, and careful postoperative surveillance. This approach maximizes lesion removal, ensures biomechanical stability, aids in resolving radicular symptoms, produces a stable posterior spinal fusion, and minimizes recurrence.
