Gnathostoma spinigerum can cause subarachnoid hemorrhage (SAH). The detection of specific antibodies in serum against G. spinigerum antigen is helpful for diagnosis of neurognathostomiasis. There is limited data on the frequency of G. spinigerum infection in non-traumatic SAH. A series of patients diagnosed as non-traumatic SAH at the Srinagarind Hospital, Khon Kaen University, Thailand between January 2011 and January 2013 were studied. CT or MR imaging of the brain was used for diagnosis of SAH. Patients were categorized as aneurysmal subarachnoid hemorrhage (A-SAH) or non-aneurysmal subarachnoid hemorrhage (NA-SAH) according to the results of cerebral angiograms. The presence of specific antibodies in serum against 21- or 24-kDa G. spinigerum antigen was determined using the immunoblot technique. The detection rate of antibodies was compared between the 2 groups. Of the 118 non-traumatic SAH patients for whom cerebral angiogram and immunoblot data were available, 80 (67.8%) patients had A-SAH, whereas 38 (32.2%) had NASAH. Overall, 23.7% were positive for specific antibodies against 21- and /or 24-kDa G. spinigerum antigen. No significant differences were found in the positive rate of specific antibodies against G. spinigerum in both groups (P-value=0.350).

Nontraumatic intracranial subarachnoid hemorrhage (SAH) attributable to the thoracolumbar dural arteriovenous fistulas (DAVFs) has been extremely rare. A 41-year-old male patient was admitted with severe acute headache, neck stiffness, and pronounced low-back pain radiating to both legs. The T2-weighted MR imaging showed irregular signal void and enlarged, varix like pouch formation with spinal cord compression at the T11-12 level. The angiogram revealed a DAVF. We report a DAVF case with SAH that revealed an extensive infarction from C5 to the conus medullaris after undergoing operative treatment.

목적 : 급성 거미막하 출혈의 진단에 있어 CT와 비교하여 fluid-attenuated inversion-recovery (FLAIR) MR영상의 유용성을 평가하고자 하였다. 대상 및 방법 : 증상 발생 3일 이내에 비조영 CT와 FLAIR MR영상을 모두 얻었던 28명의 급성 지주막하 출혈 환자를 대상으로 하였다. 거미막하 공간을 피질구, 실비우스열구, 기저조, 후두와의 4부위로 나누어 각 부위 별로 CT와 FLAIR영상에서 출혈이 보이는 정도를 0(출혈 없음), 1(출혈 의심), 2(뚜렷한 출혈)의 점수로 구분하여 평가하였다. 또한 이들 28명 환자와 대조군 35명의 FLAIR영상을 비교하여 거미막하 공간의 고신호 강도를 기준으로 출혈의 유무를 판정할 경우, FLAIR영상의 민감도, 특이도 및 진단적 정확도를 평가하였다. 결과 : FLAIR영상에서 급성 거미막하 출혈은 모든 환자에서 뇌척수액이나 뇌 실질보다 고신호 강도를 보여 100%의 발견율을 보였다. CT와 비교하여 피질구($1.11{\pm}0.80$ vs $0.70{\pm}0.83$: p(0.05)와 후두와($1.41{\pm}0.74$ vs $0.78{\pm}0.80$: p(0.05)에서 FLAIR영상이 CT보다 통계적으로 유의하게 우수하였다 FLAIR영상에서 거미막하 공간의 고신호 강도를 기준으로 거미막하 출혈 유무를 평가한 결과에서 100%의 민감도, 특이도 및 진단적 정확도를 보였다. 결론 급성 거미막하 출혈의 진단에 FLAIR MR영상은 매우 유용하며, 특히 출혈의 양이 소량인 경우와 후두와의 출혈을 진단하는데 CT보다 우수하다.

Aneurysmal subarachnoid hemorrhage (SAH) during pregnancy is quite rare, however it has a high maternal mortality rate. A pregnant woman in the 16th gestational week was admitted to our hospital with a drowsy level of consciousness. A brain magnetic resonance (MR) image showed hemorrhage on the prepontine cistern, and both sylvian fissures, and MR angiography and cerebral digital subtraction angiography demonstrated an aneurysm at the left posterior inferior cerebellar artery (PICA). We performed endovascular coil embolization attempting to minimize radiation exposure. She was discharged with no neurologic deficit and delivered a healthy baby by cesarean section at the 38th week of gestation. This case study reported the shortest gestational period and this is the first report on an aneurysmal rupture arising from PICA which was treated using an endovascular method. Using an appropriate technique for reduced radiation exposure to the fetus and limited alterations in maternal-fetal physiology, endovascular coil embolization could guarantee good results in treatment of aneurysmal SAH in pregnant women.
