However, some patients, who develop severe brain sagging, can neurologically deteriorate, and in occasional instances, which become comatose. Here, with the presentation of two cases, and a review of the literature, we have set guidelines for diagnosing SIH along with recommendations for its management. We reviewed two cases of SIH. Both patients became comatose due to a CSF leak associated with a tear in the spinal dura diagnosed on myelo-CT studies. As targeted EBP failed to achieve sustained improvement, direct operative repair of the dural tears was warranted (video presentation). After reviewing two cases of SIH and the literature, we developed an algorithm for the diagnosis and management of SIH. To avoid deterioration to a comatose status, we recommend the early performance of myelo- CT studies to identify the location of the dural leak, followed by early dural repair.

Spinal teratomas are rare in adults. The clinical findings are nonspecific, reflecting only in the intramedullary location of these lesions. The potential differential diagnosis for intramedullary spinal teratomas include schwannomas, dermoids, epidermoids, and neurofibromas. A 25-year-old male presented with RLE weakness (iliopsoas/quadriceps [4/5], and extensor hallucis longus/dorsiflexor [0/5]) and urinary incontinence. As the contrast, MR showed a heterogeneous intramedullary lesion with well-defined edges located at the T12-L1 level, the patient underwent a focal laminectomy for gro
