RESUMO
Objective: to describe the surgical treatment of an anterior sacral meningocele (ASM). Description: a 67 year-old woman presented with pelvic mass symptoms, and had a previous history of four surgeries with mistaken diagnosis, consulted to the neurosurgery departament for pain treatment. MRI revealed a cystic sacral mass connected with the spinal subarachnoid space, with low density structures in the pedicle. MyeloCT showed no neural elements in the sac. Intervention: an anterior transabdominal approach with wall cyst dissection, excision of the sac and simple ligation of the neck was performed. Conclusion: we presented an uncommon case of ASM in an adult woman, with the transabdominal surgical approach was the treatment of choice in anterior sacral meningocele
