Abstract：
Primary intramuscular hydatid cysts are uncommon due to the contractile nature of muscles and their lactic acid content. Hydatid cysts with spinal extension are sometimes seen with primary vertebral body involvement. Our patient presented with a slow-growing posterior abdominal wall mass, and upon magnetic resonance imaging (MRI), it was revealed to be several cystic lesions in the abdomen wall with extension through the neural foramina into the spinal canal. The key differentials for spinal canal masses with neural foraminal expansion and muscle involvement are peripheral nerve sheath tumors. Our case report adds hydatid cysts to the differentials for well-defined cysts with variable intensities on MRI.
摘要：
由于肌肉的收缩性质及其乳酸含量，原发性肌内包虫囊肿并不常见。有时可以看到带有脊柱延伸的包虫囊肿，并累及原发性椎体。我们的患者表现为缓慢增长的后腹壁肿块，磁共振成像(MRI)，发现腹壁有几个囊性病变，并通过神经孔延伸到椎管。具有神经椎间孔扩张和肌肉受累的椎管肿块的关键区别是周围神经鞘瘤。我们的病例报告在MRI上强度可变的明确定义的囊肿的差异中增加了包虫囊肿。
