Extramedullary hematopoiesis generally occurs in a variety of hematological disorders where the normal functioning of the blood forming organs is disturbed. It is a common manifestation in thalassemia where it occurs as a compensatory phenomenon in order to combat long standing anemia. Spinal cord compression as a consequence of extramedullary hematopoiesis in the intraspinal epidural space is an extremely rare complication, though this complication has been reported more commonly in thalassemia.
A case of spinal cord compression due to extramedullary hematopoiesis in a patient with thalassemia is reported. The patient was successfully treated with radiation therapy and blood transfusions and he made a complete clinical recovery. Development. The literature is reviewed and the efficacy of several treatments such as surgery, radiotherapy and blood transfusion therapy is discussed. Until recently surgical decompression followed by radiation therapy remained the recommended treatment. Hematopoietic tissue is particularly sensitive to the ionizing radiation and low-dose radiotherapy is enough to relieve the spinal cord compression. Blood transfusion therapy may be diagnostically and therapeutically useful in the management of this entity.
A prompt recognition of the syndrome and early treatment with radiotherapy and blood transfusion therapy is recommended to prevent irreversible damage to the spinal cord. Surgery may be only considered in the event of progressive neurological deficit despite of radiotherapy or blood transfusion therapy.
髓外造血通常发生在多种血液系统疾病中,这些疾病会干扰造血器官的正常功能。它是地中海贫血中的常见表现,作为一种代偿现象出现以对抗长期贫血。脊髓硬膜外间隙髓外造血导致的脊髓压迫是一种极其罕见的并发症,尽管这种并发症在地中海贫血中报道更为常见。
报告了一例地中海贫血患者因髓外造血导致脊髓压迫的病例。该患者通过放射治疗和输血成功治疗,临床完全康复。发展。回顾了文献并讨论了手术、放疗和输血治疗等几种治疗方法的疗效。直到最近,手术减压后放疗仍是推荐的治疗方法。造血组织对电离辐射特别敏感,低剂量放疗足以缓解脊髓压迫。输血治疗在该疾病的管理中可能具有诊断和治疗价值。
建议迅速识别该综合征并早期进行放疗和输血治疗,以防止脊髓发生不可逆损伤。仅在尽管进行了放疗或输血治疗仍出现进行性神经功能缺损的情况下才考虑手术。
