Postdural disc herniation has been documented rarely and the pathogenesis is still unknown. The average age of postdural disc herniations is between 50 and 60 years, and the sites most frequently affected by postdural lumbar disc herniations are L3-L4 and L4-L5, only less than 10 % in L5-S1. Although magnetic resonance imaging (MRI) is a useful tool in the diagnosis of this disease, the postdural disc herniation is usually misdiagnosed as extradural spine tumor preoperatively. The definitive diagnosis is made during operation or according to the postoperative pathology. ⋯ The diagnosis of postdural disc herniations is very difficult and mainly based on intraoperative and histopathological results. Early surgical intervention is important to relieve symptoms and prevent severe neurological deficits.

We report a case of a large three-level spinal osteosarcoma infiltrating the adjacent aorta. This is the first case in which a combined modified three-level en bloc corpectomy with resection and replacement of the adjacent aorta was successful as a part of interdisciplinary curative treatment. ⋯ Combined corpectomy with aortic replacement should be considered as a reasonable option in the curative treatment of osteosarcoma with consideration of the immense surgical risks. The use of an HLM is not necessary, especially considering the inherent risk of hematogenous tumor metastases. Modified corpectomy leaving a dorsal vertebral body segment was considered a reasonable variation since tumor-free margins could still be expected.

Safe treatment of giant central thoracic disc herniations (cTDHs) remains a surgical challenge due to frequent calcifications, intradural extension and, importantly, the rare exposure of spine surgeons to these lesions. We report our 10-year experience in the management of giant cTDH by mini-thoracotomy and offer a detailed description of the technique. ⋯ Patients with myelopathy due to giant cTDH can be safely treated by the mini-thoracotomy approach. Postoperative neurological worsening and severe complications or incisional pain are rare. In contrast to complex posterior or thoracoscopic approaches, the mini-thoracotomy is technically straightforward and thus easy to learn for experienced spine surgeons.

Minimally invasive transforaminal lumbar interbody fusion (misTLIF) can potentially lead to dorsal root ganglion (DRG) injury which may cause postoperative dysesthesia (POD). The purpose of retrospective study was to describe the uncommon complication of POD in misTLIF. ⋯ Although POD is a unique and rare complication and maybe misdiagnosed as nerve root injury in misTLIF, combination drug therapy and DRG block have an effective result of pain relief. The appearance of a gradual pain moving to distal end of a proper DRG innervated region during recovery may be used as a sign for the good prognosis.

Case Reports
Communicating hydrocephalus, a long-term complication of dural tear during lumbar spine surgery.
Iatrogenic dural tears during lumbar spine surgery are not uncommon and may have multiple long-term sequelae if not managed promptly and definitively. Sequelae include pseudomeningocoeles due to a persistent cerebrospinal fluid leak, which may result in a subarachnoid hemorrhage or subdural hematoma. These, in turn, can lead to adult communicating hydrocephalus. The purpose of this study is to describe a case of an intraoperative iatrogenic dural tear leading to the formation of a pseudomeningocoele and progressing to hydrocephalus. ⋯ The need for prompt recognition and proper management of iatrogenic dural tears are emphasized in order to avoid future complications that may arise from inadequate or proper treatment.
