Abstract：
Primary central nervous system lymphoma is a rare form of extranodal non-Hodgkin\'s lymphoma that occurs in the brain, spinal cord, leptomeninges, or eyes and typically remains confined to the central nervous system. Among them, malignant lymphoma presenting as a primary tumor of the spinal cord is extremely uncommon, and epidural mass formation is known to occur in only 0.8-2.8% of cases of malignant lymphomas. Furthermore, primary malignant lymphoma presenting as an isolated epidural mass is much rarer. Here, we report a case of primary malignant lymphoma of the thoracic spine presenting as an isolated epidural mass that did not involve the vertebral body or posterior element. Surgical decompression is essential to prevent further neurological deterioration. Here, we present a successful treatment strategy for this rare case.
摘要：
原发性中枢神经系统淋巴瘤是一种罕见的结外非霍奇金淋巴瘤，发生在大脑中，脊髓,软脑膜,或眼睛，通常局限于中枢神经系统。其中,恶性淋巴瘤表现为脊髓的原发性肿瘤是非常罕见的，已知硬膜外肿块形成仅在0.8-2.8％的恶性淋巴瘤病例中发生。此外，原发性恶性淋巴瘤表现为孤立的硬膜外肿块更为罕见。这里,我们报告了一例原发性胸椎恶性淋巴瘤，表现为孤立的硬膜外肿块，不涉及椎体或后部。手术减压对于防止神经进一步恶化至关重要。这里,我们为这一罕见病例提供了成功的治疗策略.
