RESUMEN
Thoracic meningocele is a rare medical condition that is usually linked to neurofibromatosis type I.1 Respiratory and neurologic symptoms characterize it.2 Although there have been some improvements in surgical techniques, the condition has a high recurrence rate, with most cases recurring within a year of surgery.3 A 56-year-old woman was observed due to respiratory and pyramidal signs. A chest computed tomography scan and magnetic resonance imaging revealed a thoracic meningocele, occupying the lower sectors of the right hemithorax, communicating with the cerebrospinal fluid space at the T10-T11 level. Multidisciplinary surgery was performed. After selectively intubating both bronchi, the patient was placed in prone position and a posterior median thoracic spine approach was performed. After T10-T11 laminectomy, 3 dural longitudinal incisions were performed. The first incision was placed in the middle to deflate the collection, the second was made on the right side to obtain a complete view of the meningocele, and the third was made on the right lateral side to exclude the meningocele. The lateral dura at the last incision was sutured to the dura propria lining the vertebral body of T11 and T10. The paramedian and median incisions were closed, with Tachosil placed above and below the sutures. Subsequently, the patient was placed in a supine position, the right lung was deflated, and a triportal thoracoscopic approach was performed to dissect and remove the lesion.4 The breach was closed using Tachosil (Baxter Healthcare Corp, Deerfield, Illinois, USA) and fibrin glue. An early 1-month computed tomography and magnetic resonance imaging confirmed the surgery was successful.
