목적: 방사성 동위원소 뇌조조영술은 자발성 두 개 내 저압환자의 체위성 두통과 저뇌척수압의 병태생리를 이해하는데 도움을 줄 수 있다. 저자들은 이 질환의 방사성 동위원소 뇌조조영술의 특징적인 소견을 알아보고자 하였다. 대상 및 방법: 자발성 두개내 저압으로 진단되어 방사성 동위원소 뇌조조영술을 시행한 15명을 대상으로 하였다. 뇌조조영술은 Tc-99m DTPA 111-222 MBq를 요추천자를 통해 지주막하강에 투여한 후 감마카메라로 30분부터 2시간 이내에 방광을 포함한 요추부와 경흉추부의 전면상과 측면상을 얻었고, 4, 6, 24시간에 두부와 경흉추부의 전면상과 측면상을 얻었다. 방광 내 방사성 추적자의 조기 배설유무, 척수강 내 방사성의 이동속도, 연조직 섭취정도, 그리고 대뇌궁융부로의 이동 지연 등을 분석하였다. 결과: 방사성 동위원소 뇌조조영술 소견은 대뇌궁융부로의 방사성 추적자의 이동지연(14/15), 연조직의 섭취증가(11/15), 방광 내 방사성 추적자의 조기 출현(13/13) 등이 있었고 뇌척수액의 누출을 시사하는 척수경막강 주위의 방사성 추적자의 국소 집적도 4예에서 있었다. 결론: 방사성 추적자의 이동 지연과 연조직의 섭취증가 및 방광 내 방사성 추적자의 조기 출현 등이 특징적으로 관찰되었고, 이러한 뇌조조영술 소견은 자발성 두개 내 저압의 주된 병태생리가 뇌척수액의 누출임을 시사하는 것으로 판단되었으며, 방사성 추적자 이동의 역동적 측면을 잘 평가하기 위해서는 방광과 연조직을 포함한 30분 영상과 다발적인 연속영상을 획득하는 것이 필요하다고 생각된다.

Although cerebrospinal fluid leakage is suggested as one of the causes of spontaneous intracranial hypotension, only a few cases with direct evidence of cerebrospinal fluid leakage on radionuclide cisternography have been reported in the literature. Indirect evidences of cerebrospinal fluid leakage such as early visualization of the soft tissue and bladder or delayed migration of radiotracer have been observed in most patients with spontaneous intracranial hypotension. We report a case of spontaneous intracranial hypotension in which cerebrospinal fluid leakage was directly demonstrated by early dynamic imaging of spine on radionuclide cisternography. We suggest that early dynamic imaging of spine is an important adjunctive procedure in detecting cerebrospinal fluid leakage in patients with spontaneous intracranial hypotension.

Spontaneous intracranial hypotension(SIH) is a rare syndrome of spontaneously occurring postural headache associated with low CSF pressure. It usually occur without evidence of any preceeding events such as lumbar puncture, back trauma, operative procedure, or medical illness. This syndrome usually resolves spontaneously or with strict bed rest. When the headache persists or is incapacitating, more aggressive treatment may be necessary. Autologous epidural blood patch is highly effective in the management of SIH. We experienced a case of SIH with downward displacement of brain in MRI and successfully treated with epidural blood patch.

Spontaneous intracranial hypotension, a syndrome of low CSF pressure, occurs without preceding events such as lumbar puncture, back trauma, operative procedure or medical illness. The most characteristic symptom is an occipital or frontal headache which is aggrevated in the erect position and relieved in the supine position. This syndrome usually resolves spontaneously or with strict bed rest. When the headach persists or is incapacitating, more aggressive treatment may be necessary. Autologous epidural blood patch is highly effective in the management of spontaneous intracranial hypotension. Epidural blood produces an organized clot which effectively tamponade any dural CSF leak. The rapid relief of headache immediately after the infusion of blood occur by some other mechanism, such as an increase in subarachnoid pressure that is known to occur with infusion of fluid into the lumbar epidural space. We report three cases of spontaneous intracranial hypotension successfully treated with epidural blood patch.

We report a patient with spontaneous intracranial hypotension. In addition to the cardinal feature of a postural headache and a low CSF pressure, the patient also had subdural hematoma demonstrated by brain MRI. Radionuclide cisternography revealed a CSF leakage in the intracranium. CSF leakage from spinal meningeal defects may be the most common cause of this syndrome. The headache is a consequence of the low CSF pressure producing displacement of pain-sensitive structures. Methods of treatment are identical to those for post-dural puncture headaches. We experienced a patient with spontaneous intracranial hypotension developed in the intracranium who was successfully managed with a cervical blood patch.

This report describes the successful treatment of spontaneous intracranial hypotension (SIH) with multiple cerebrospinal fluid (CSF) leaks using 10 applications of epidural blood patches (EBP). A forty year old female who suffered with a postural headache was diagnosed as having SIH. On the cisternography, multiple CSF leaks were noted at the thoracic and lumbar area. Her headache was not improved with conservative treatments such as bed rest, hydration and NSAIDS. So, she underwent treatment with EBPs. After 10 applications of site-directed EBPs, her headache was resolved gradually and completely without any complications.

Background: Spontaneous intracranial hypotension is a syndrome characterized by postural headache without trauma, spinal anesthesia or other medical history. The purpose of this study is to analyze the effect of epidural blood patch in spontaneous intracranial hypotension. Methods: The spontaneous intracranial hypotension patients treated with epidural blood patch were analyzed on the symptoms, radiologic images and methods of epidural blood patch retrospectively by the medical records. Results: Patients had postural headache (15 patients) including nausea/vomiting (10 patients), tinnitus (2 patients), neck stiffness (13 patients), vertigo (3 patients) and occular pain (1 patient). Brain CT and MRI showed diffuse enhancement of the pachymeninges (9 patients) and radionuclide cisternography demonstrated direct evidence of leakage (11 patients). With epidural blood patch, the symptoms were promptly relieved in 11 patients. Conclusions: We concluded that epidural blood patch is a good treatment of method in spontaneous intracranial hypotension patients.

Spontaneous intracranial hypotension (SIH) is a rare syndrome which causes postural headache associated with low cerebrospinal fluid (CSF) pressure, without preceding events such as lumbar puncture, back trauma, operative procedure or illness. The headche is usually accompanied by nausea, vomiting, tinnitus, neck stiffness, vertigo, photophobia and in rare cases diplopia, transient visual obscuration. Brain MRI may show subdural effusion, downward displacement of brain and diffuse and continuous meningeal enhancement when enhanced by gadolinium. Low opening pressure was shown through lumbar puncture. The value of protein and cell count of CSF may be slightly elevated. This syndrome usually resolves itself spontaneously or with strict bed rest. When the headache is persistent or incapacitating, more aggressive treatment may be necessary. We treated two cases of SIH in which epidural blood patch produced immediate and complete relief of the symptoms.
