Spinal metastasis of neuro-endocrine tumours (NETs) usually arise from a primary in the lung. We encountered such a patient with NET metastasis to T6 vertebra causing severe cord compression. Considering the neurological status, immediate decompression surgery along with T3-T8 posterior stabilization was done. Early recurrence of the tumour causing near total obliteration of the spinal canal leading to significant neurological compromise was noted within one month of surgery. A second surgery at this stage was avoided due to the risk involved and concurrent chemo-radiotherapy was initiated. The tumour was sensitive to chemo-radiotherapy and rapid resolution was noted on subsequent follow-up visits. With appropriate rehabilitation, patient regained full power to become ambulant with support. This case report highlights a rare, early and aggressive recurrence of metastatic vertebral NET following index surgery which was effectively managed with chemo-radiotherapy.
神经内分泌肿瘤(NETs)的脊柱转移通常源于肺部的原发性肿瘤。我们遇到了这样一位患者,其NET转移至T6椎体,导致严重的脊髓压迫。考虑到神经状况,立即进行了减压手术,并同时进行了T3 - T8后路固定。术后一个月内,发现肿瘤早期复发,几乎完全阻塞了椎管,导致严重的神经功能损害。由于手术风险,此阶段避免了二次手术,并开始进行同步放化疗。肿瘤对放化疗敏感,在随后的随访中可见迅速缓解。经过适当的康复治疗,患者恢复了全部力量,在辅助下能够行走。本病例报告强调了转移性椎体NET在初次手术后罕见、早期且侵袭性的复发情况,通过放化疗得到了有效控制。
