Postural headache due to spontaneous intracranial hypotension occurs without any diagnostic lumbar puncture, myelography, cranial or spinal injury, or spinal anesthesia. The clinical characteristics of the syndrome are disappearance of the headache or a notable decrease in its severity with recumbency, the finding of meningeal enhancement and subdural fluid collection on brain MRI, the pleocytosis and the increased CSF protein concentration. We report a case of a 40-year-old woman who exhibited the signs and symptoms of postural headache due to low CSF pressure. Her headache started suddenly at the occiput and radiated to frontal head. Magnetic resonance imaging (MRI) of her brain showed enhancement of the meninges and subdural fluid collection. Intrathecal radionuclide cisternography showed the delayed appearance of the isotope in the cranium and the minimal CSF leak at the left upper thoracic region. Her headache was relieved completely after a lumbar (L2-L3) epidural injection of 12 ml of autologous blood and remained asymptomatic.

Chronic subdural hematoma (SDH) is a well-known disease entity and is traditionally managed with surgery. However, when associated with spontaneous intracranial hypotension (SIH), the treatment strategy ought to be modified, as classical treatment could lead to unwanted consequences. A 59-year-old man presented with a case of SIH that manifested as a bilateral chronic SDH. He developed fatal extensive pneumocephalus and SDH re-accumulation as a complication of burr-hole drainage. Despite application of an epidural blood patch, the spinal cerebrospinal fluid leak continued, which required open spinal surgery. Chronic SDH management should not be overlooked, especially if the exact cause has not been determined. When chronic SDH assumed to be associated with SIH, the neurosurgeon should determine the exact cause of SIH in order to effectively correct the cause.

Background: An epidural blood patch (EBP) is a procedure to treat intracranial hypotension that does not respond to conservative treatment. EBPs are commonly repeated when the symptoms persist. In this study, we used a large single-center retrospective cohort and evaluated the factors associated with repeated EBPs. Methods: From January 2010 to December 2020, a total of 596 patients were treated with EBPs for intracranial hypotension. We evaluated the factors associated with repeated EBPs in the entire population, in patients with spontaneous intracranial hypotension (SIH), and in those with available myelographies. Results: In a total of 596 patients, 125 (21.1%) patients required repeated EBPs, and 96/278 (34.5%) in SIH and 29/314 (9.2%) in iatrogenic population. In patients with SIH, international normalized ratio (INR) and cerebrospinal fluid (CSF) leakage on myelographies consistently exhibited significant associations (odds ratio [OR], 1.38; 95% confidence interval [CI], 1.02-1.87; P = 0.043 and OR, 2.18; 95% CI, 1.28-3.69; P = 0.004). In patients with iatrogenic injury, INR and CSF leakage on myelogram did not show difference in repeated EBPs. Conclusions: Repeated EBPs may be more frequently required in patients with SIH. Prolonged INR and CSF leakage were associated with repeated EBPs in patient with SIH. Further studies are needed to determine factors associated with repeated EBP requirements.

목적 : 방사성동위원소 뇌조조영술은 자발성 두개강내 저뇌압증이 의심되는 환자에서 뇌척수액의 누출을 진단하는데 유용한 검사이지만, 뇌척수액의 누출 부위를 증명하지 못하는 경우가 있다. 본 연구의 목적은 방사성동위원소 뇌조조영술의 검사 방법을 변화함으로써 뇌척수액 누출 부위의 진단율을 향상시키고, 검사 소요시간을 단축할 수 있는지 알아 보고자 한다. 대상 및 방법 : 자발성 두개강내 저뇌압증으로 진단되어 방사성동위원소 뇌조조영술을 시행한 7명의 환자(평균 나이=$38{\pm}8$세, 남자 2명, 여자 5명), 8회 검사를 대상으로 하였다. 모든 환자들은 자주막하강에 $^{99m}Tc$-DTPA 185-222 MBq을 투여한 후 10분, 30분, 1시간, 2시간, 4시간 그리고 6시간에 방광을 포함하는 요추부부터 두부까지의 영상을 얻었다. 그리고 영상시간에 따라 뇌척수액의 누출과 방광의 방사능 조기 출현을 평가하였다. 결과: 방사성동위원소 뇌조조영술을 통해 8예 모두에서 뇌척수액의 누출 부위를 확인할 수 있었다. 뇌척수액의 누출 부위는 경흉추 경계부(cervico-thoracic junction)에서 3예, 경흉추 경계부와 C1-2에서 2예, 경흉추 경계부와 흉추부, 흉요추부 여러 곳 그리고 요추부가 각각 1예씩 이었다. 모든 예에서 1시간까지의 영상을 통해 모든 예에서 뇌척수액의 누출 부위를 발견할 수 있었으며, 모두 두 곳 이상에서 누출이 있었다. 이 중 경흉추 경계부를 포함하는 경우가 5예였다. 지연 영상에서 뇌척수액의 누출 부위가 추가로 발견된 경우는 단 1예 뿐 이었다. 조기 방광방사능 출현은 6예에서 관찰되었으며, 모두 뇌척수액 유출부위가 더 먼저 관찰되었다. 결론: 방사성동위원소 뇌조조영술은 자발성 두개강내 저뇌압증 환자에서 뇌척수액의 누출 부위를 확인하는데 매우 예민한 검사이며, 검사법을 변형함으로써 뇌척수액의 누출 부위를 발견하는 빈도를 향상시키고, 검사시간을 단축할 수 있을 것으로 기대된다.
