  • Objective : Diffusion-weighted magnetic resonance imaging (DW-MRI) has proven useful in the study of the natural history of ischemic stroke. However, the potential of DW-MRI for the evaluation of chronic subdural hematoma (CSDH) has not been established. In this study, we investigated DW-MRI findings of CSDH and evaluated the impact of the image findings on postoperative outcomes of CSDH. Methods : We studied 131 CSDH patients who had undergone single burr hole drainage surgery. The images of the subdural hematomas on preoperative DW-MRI and computed tomography (CT) were divided into three groups based on their signal intensity and density : 1) homogeneous (iso or low) density on CT and homogeneous low signal intensity on DW-MRI; 2) homogeneous (iso or low) density on CT and mixed signal intensity on DW-MRI; and 3) heterogeneous density on CT and mixed signal intensity on DW-MRI. On the basis of postoperative CT, we also divided the patients into 3 groups of surgical outcomes according to residual hematoma and mass effect. Results : Analysis showed statistically significant differences in surgical (A to B : p<0.001, A to C : p<0.001, B to C : p=0.129) and functional (A to B : p=0.039, A to C : p<0.001, B to C : p=0.108) outcomes and treatment failure rates (A to B : p=0.037, A to C : p=0.03, B to C : p=1) between the study groups. In particular, group B and group C showed worse outcomes and higher treatment failure rates than group A. Conclusion : CSDH with homogeneous density on CT was characterized by signal intensity on DW-MRI. In CSDH patients, performing DW-MRI as well as CT helps to predict postoperative treatment failure or complications.

  • Eikenella corrodens는 구강 상재균으로 두경부 감염을 주로 일으키나 면역력이 정상인 소아청소년에게 감염을 일으키는 경우는 흔하지 않다. 저자들은 발열, 두통, 구토를 증상으로 입원한 이전까지 건강하였던 13세 남자에게서 E. corrodens 감염에 의한 중추신경계 경막 외 농양을 진단하여 보고하는 바이다. 초기에 시행한 신체검진에서 경부 강직은 없었으나, 우측 이루가 관찰되었다. 뇌 magnetic resonance imaging (MRI) 영상소견에서 4.5 cm 크기의 경막 외 농양이 우측 측두엽 부근에서 발견되었고, 양측 사골동염 및 접형동염, 우측 유양돌기염과 중이염이 동반되었다. Vancomycin과 cefotaxime 투약 중에도, 임상증상이 호전되지 않고 추적 MRI에서 경막 외 농양의 크기가 증가하고, 우측 접형동에 농양이 형성되어 항균요법과 함께 천두술과 내시경적 접형동 절개술을 시행하였다. 수술 시 경막 외 농양과 접형동에서 악취가 나는 고름이 다량 흡인되었으며 두 부위에서 흡인된 검체 모두에서 E. corrodens가 배양되었다. 수술 이후 3주 동안 cefotaxime 정맥주사로 치료받고 합병증 없이 회복하였다. 결론적으로, E. corrodens는 건강한 소아청소년에서 치료되지 않은 세균성 부비동염에 합병하여 중추신경계 농양의 원인이 될 수 있다.
