There have been major advances in the diagnosis and treatment of spontaneous intracranial hypotension (SIH). While once thought to be a rare condition, the occurrence is not uncommon if diagnosed adequately. Our greater understanding of SIH is based on three main points: (1) awareness of the various types of spontaneous spinal cerebrospinal fluid (CSF) leaks; (2) advanced myelography with the precision to detect dural tears and CSF-venous fistulas; and (3) updated treatment techniques of epidural patching, embolization, and surgery. This review discusses the various types of epidural patching for CSF leaks.
