Abstract

Postsurgical pseudomeningoceles are extradural collections of cerebrospinal fluid (CSF) that results following an intraoperative dural breach. Although usually asymptomatic and self-subsiding, they may present with symptoms of postural headache, blurred vision, diplopia, photophobia, back pain, radiculopathy, and vomiting. Most of the cases recover with conservative measures such as bed rest, hydration, and pressure dressings. Symptomatic patients usually require surgical re-exploration and direct open repair of the durotomy. We report the case of a 48-year-old female who presented with lumbar pseudomeningocele following lumbar microdiscectomy treated by Ultrasound-guided (USG)-guided epidural blood patch application. She had globular swelling at the surgical site, postural headache, and left lower-limb radicular pain with normal neurology. Her magnetic resonance imaging (MRI) showed a left L4 laminar defect with pseudomeningocoele (measuring 5.5 cm × 4.2 cm × 4 cm) with intraspinal communication. USG was used to guide the aspiration of CSF from pseudomeningocele and to apply the epidural blood patch one level above and at the level of laminectomy. Postoperatively, she had marked improvement in her symptoms. At 1-year follow-up, she was completely symptom free and full resolution of pseudomeningocele was seen on 1-year follow-up MRI. This case is being reported to highlight the use of USG-guided epidural blood patch for the treatment of postoperative lumbar pseudomeningocele.

Key-words:
