RESUMO
In most cases of post-dural puncture headache, the positional symptoms will resolve spontaneously within 2 weeks. Conservative therapies include oral analgesics and hydration, bed rest, and abdominal binders. For refractory cases, an autologous epidural blood patch remains the treatment of choice. However, in certain cases the use of autologous blood for the blood patch may place the patient at risk for infectious or malignant contamination of the central nervous system. Coccidioidomycosis results from inhalation of the arthroconidia (spore) stage of the fungal lifecycle. The most common manifestation of coccidioidomycosis is acute pulmonary symptoms, while the most feared complication is meningitis. Immunocompromised patients are at increased risk of fungemia; therefore, introduction of fungal elements into the central nervous system can occur if autologous blood is used for an epidural blood patch. We report a case of persistent dural-puncture headache in the setting of disseminated coccidioidomycosis. An autologous blood epidural blood patch was considered but deferred due to risk of coccidioidomycosis meningitis. Other epidural space interventions such as fibrin glue injection or saline infusions were judged to be too imprecise or ineffective. The patient was successfully treated with allogeneic blood donated by his wife, but only after testing of her blood as is required for any directed blood donation. Allogeneic epidural blood patches are an option for refractory dural puncture headaches when autologous blood may cause meningitis or malignant seeding of the central nervous system.

OBJECTIVE: The purpose of this study is to discuss the presentation, examination, diagnosis, and treatment of a case of intracranial hypotension presenting to a chiropractic office as acute severe headache and neck pain. CLINICAL FEATURES: Flexion injury during a weight lift resulted in a severe postural headache and upper cervical spine pain in a 51-year-old man. The patient presented with unusual symptoms, but normal palpatory findings, and a lack of postural distortion. INTERVENTION AND OUTCOME: Based on the history, symptoms, and examination findings, the patient was referred for an emergency medical evaluation. A diagnosis of intracranial hypotension was made, and a dural leak was confirmed by radioisotope cisternography. The patient made a complete recovery. CONCLUSIONS: Intracranial hypotension can cause headache and neck pain that may appear to be musculoskeletal in nature. The key symptom is the orthostatic nature of the headache.

BACKGROUND CONTEXT: Intracranial hypotension (IH) is a syndrome in which volume depletion of the cerebrospinal fluid (CSF) results in various neurological symptoms. Most commonly, a small tear or defect in the spinal dural sac is the underlying lesion that results in a CSF leakage and IH. Causes of IH can be classified as 1) spontaneous (primary), and 2) secondary. Knowledge of IH is essential to spine surgeons, because a small proportion of patients with spontaneous IH require spine surgery, and secondary causes of IH include spine trauma, various spine-related diagnostic/therapeutic procedures (iatrogenic), and degenerative spine disorders. PURPOSE: The purpose of this review is to update knowledge of IH pertinent to spine surgery. STUDY DESIGN/SETTING: Review of the literature. METHODS: A systematic review of the literature was conducted using PUBMED. The literature regarding IH with spinal pathology published from 1966 to 2005 was searched and reviewed comprehensively. RESULTS/CONCLUSIONS: The lower cervical and upper thoracic spine are the predilection sites for a CSF leak in patients with spontaneous IH. Mechanical stress may have a role in the pathogenesis of spontaneous IH, and meningeal diverticula and connective tissue disorders may be important risk factors. Iatrogenic causes of IH include lumbar puncture, spine surgery, and chiropractic manipulation. Rarely, degenerative spine disorders are the secondary cause of IH. Although orthostatic headache is the characteristic symptom of IH, a small proportion of patients present with neck pain or radicular symptoms of the upper extremity. Imaging studies of the spine have contributed significantly to elucidation of the pathophysiology of IH as well as identification of the site of a CSF leak. Typical spinal radiographic findings of IH include extra-arachnoid or extradural fluid collections, meningeal enhancement, engorgement of the epidural venous plexus, and tonsilar descent into the foramen magnum. Most patients with spontaneous IH respond favorably to conservative management, including autologous epidural blood patch. Surgical intervention is reserved for those who fail the conservative management. Although immediate clinical improvement is usually achieved by surgery, the long-term outcomes of surgical patients need to be investigated further. In patients who have a secondary cause of IH, treatment of the underlying lesion or condition may terminate a CSF leak and result in reversal of symptoms.
