Symptomatic Postoperative Spinal Subdural Extra-Arachnoid Hygromas: Resolution with Conservative Management: A Report of 2 Cases.

CASE

Two cases of postoperative spinal subdural extra-arachnoid hygromas were successfully treated with bed rest after patients developed symptoms 4 to 5 days following decompressive lumbar surgery. The development of the hygromas as well as the radiological findings are discussed.

CONCLUSION

To the best of our knowledge, these comprise the first postoperative cases successfully treated without surgical re-exploration. This demonstrates conservative management may be a safe and effective management choice.
