Review
Surgical management of spinal liposarcoma: a case series of 7 patients and literature review.
Liposarcoma, one of the most common soft tissue sarcomas originates from primitive mesenchymal cells. But spinal involvement of either primary or metastatic liposarcoma is rare. Here we present our experience of seven consecutive patients with spinal liposarcoma. ⋯ The outcome and prognosis of spinal liposarcoma is poor, and surgical resections should be considered when diagnosis is confirmed. For those whose tumors were too large to resect and/or with multiple metastases, effective treatment options are currently limited. Therefore, multidisciplinary treatment should be adopted, intraoperative chemotherapy, systemic chemotherapy and radiotherapy for instance.

Vertebral artery loop is a congenital or acquired anomaly. Vertebral artery loops are incidentally diagnosed during evaluation of neck problems and trauma. We aimed to present the incidence of VA loops using magnetic resonance angiography in consecutive patients and discuss epidemiological data including the gender, age, location, signs and symptoms, treatment approaches and outcomes of VA loops via analyzing literature. ⋯ Concise pre-operative evaluation of the vertebral arteries is essential to avoid the injury of undiagnosed VA loops during surgery, which might result in catastrophic circumstances. Further evaluation of the vertebral arteries using MR angiography is required, especially in elder age, before cervical spine surgeries.

Minimally invasive resection of extradural dumbbell tumors of thoracic spine: surgical techniques and literature review.
Dumbbell-shaped thoracic tumors represent a distinct type of tumor and involve in both the spinal canal and the posterior thoracic cavity. Successful treatment for the tumors depends on gross total resection (GTR) via an open laminectomy and facetectomy or transthoracic transpleural approach. In this case series, we report our experiments with minimally invasive method for the removal of extradural dumbbell thoracic tumor and present related literature review. ⋯ If the medial border of intracanal component of extradural dumbbell tumor is near the midline of canal and the pedicles of adjacent vertebrae to tumor are intact, minimally invasive resection of tumor through unilateral paraspinal muscle approach combined with unilateral TTIF is good choice.

Total en bloc spondylectomy for locally aggressive and primary malignant tumors of the lumbar spine.
To report outcomes after total en bloc spondylectomy (TES) for primary aggressive/malignant tumors of the lumbar spine. ⋯ Although favorable oncological outcomes after en bloc resection of spinal tumors may be achieved in terms of recurrence and survival, TES in the lumbar spine remains a challenging procedure. Future investigation into complication avoidance and reconstruction techniques is encouraged.
