Hydatid disease or hydatidosis is the most widespread zoonosis caused by . Liver and lungs are the most common sites. Bone involvement is rare and reported in 0.5%-4% with spinal involvement reported in 50% of these cases. We present a case of spinal hydatidosis in a 35-year-old male presenting with lower extremity weakness and numbness. Magnetic resonance imaging (MRI) of the spine showed multiple cystic lesions at the T9-T11 level with involvement of the paraspinal muscles. The lesion was seen intraspinal, intradural, intramedullary, and epidural. Radiological impression was aneurysmal bone cyst. The patient underwent laminectomy, and the excised cysts showed characteristic features of hydatid cyst (HC) on histopathology. The patient was started on antihelminthic therapy postoperatively. MRI is a diagnostic modality for HC, but the unusual location and absence of characteristic features can cause diagnostic difficulty. A high index of suspicion should be kept in patients residing in endemic areas and presenting with unusual cystic lesion of spine.
包虫病或囊尾蚴病是由……引起的最广泛传播的人畜共患病。肝脏和肺是最常见的发病部位。骨骼受累情况罕见，报道发生率为0.5% - 4%，其中脊柱受累占这些病例的50%。我们报告一例35岁男性脊柱包虫病病例，该患者表现为下肢无力和麻木。脊柱磁共振成像（MRI）显示T9 - T11水平有多个囊性病变，累及椎旁肌肉。病变见于椎管内、硬膜内、髓内和硬膜外。影像学诊断为动脉瘤样骨囊肿。患者接受了椎板切除术，切除的囊肿在组织病理学上显示出包虫囊肿（HC）的特征性表现。患者术后开始接受抗蠕虫治疗。MRI是诊断HC的一种方法，但不寻常的位置和缺乏特征性表现可能导致诊断困难。对于居住在流行地区且出现脊柱异常囊性病变的患者，应保持高度的怀疑指数。
