Pseudomeningocele in the lumbar spine due to spinal fractures or surgical procedures are well-recognized complications. We treated a 24-year-old man who fell from a horse, landing on his buttocks, and developed headaches, back pain, and a large lumbar subcutaneous fluid collection. Plain radiographs and magnetic resonance (MR) imaging revealed a midline defect in the sacral lamina and a large fluid collection in the subcutaneous space consistent with cerebrospinal fluid (CSF). He was treated conservatively, his symptoms resolved, and follow-up MR imaging showed resolution of the CSF accumulation. To our knowledge, there have been no cases of traumatic pseudomeningocele related to spina bifida occulta reported in the literature. The authors postulate that congenital defects in the neural arch contribute to the occurrence of this entity, and nonsurgical treatment should be the initial course.
因脊柱骨折或外科手术导致的腰椎假性脑脊膜膨出是公认的并发症。我们治疗了一名24岁男性，他从马背上摔下，臀部着地，随后出现头痛、背痛以及一个巨大的腰部皮下积液。X线平片和磁共振成像显示骶椎椎板有中线缺损，皮下间隙有一个与脑脊液（CSF）相符的巨大积液。他接受了保守治疗，症状得到缓解，随访磁共振成像显示脑脊液积聚消失。据我们所知，文献中尚未报道过与隐性脊柱裂相关的创伤性假性脑脊膜膨出病例。作者推测神经弓的先天性缺陷促成了该病症的发生，非手术治疗应作为初始治疗方案。
