AbstractSpontaneous intracranial hypotension (SIH) is a clinical syndrome in which absolute or relative hypovolemia of the cerebrospinal fluid (CSF) results in various neurological symptoms. The etiology of spontaneous CSF leaks often remains unknown. However, it is believed that the most common cause is the fragility of spinal meninges at the level of radicular nerve root sleeve. These tears can be spontaneous (primary) or secondary. Spinal pathologies can cause this tear with resultant CSF leak and SIH, which include spinal trauma, degenerative diseases and spinal surgery. Uncommonly, SIH is developed by osteophyte with disc herniation without any other pathology. In this article, we reported two cases of SIH secondary to spinal dural tear due to intradural thoracic osteophyte with superimposed disc herniation, with the absence of other pathologies, which were treated successfully with epidural blood patch (EBP).
