We report a 29-year old female who developed bilateral femoral neuropathy combined with multiple abscesses in both thigh muscles. She was present with weakness in both lower extremities for 15 days and intermittent chilling sense for 3 months. Nerve conduction study showed complete absence of compound muscle action potentials in bilateral femoral nerves when stimulated at inguinal area. Electromyographic examination revealed no motor unit action potentials in both rectus femoris and vastus medialis muscles. CT revealed multifocal abscesses in bilateral thigh muscles. After antibiotic treatment, the patient's neurologic symptoms were improved.

The decision of which surgical approach to use for the treatment of a multifocal craniofacial abscess is still a controversial matter. A failure to control disease progress in the craniofacial region can potentially put the patient's life at risk. Therefore, understanding the various ways to approach the craniofacial region helps surgeons to obtain satisfactory results in such cases. In this report, we describe a patient who visited the emergency department with a large swelling in his right cheek. A blood test and computed tomography revealed odontogenic maxillary sinusitis. The patient developed sepsis due to a progressive multifocal abscess. An abscess was seen in the temporal muscle, infratemporal fossa, and interorbital region. To control this multifocal abscess, we used the facial dismasking flap (FDF) approach. After debridement using the FDF approach, we succeeded in obtaining sufficient drainage of the abscess, and the patient recovered from sepsis. The advantages of the FDF approach are that it provides a wide surgical field, extending from the parietal region to the mid-facial region, and that it leaves no aesthetically displeasing scars on the face. The FDF approach may be one of the best options to approach multifocal abscesses in the craniofacial region.

A 4-year-old Holstein cow with progressive atrophy and ataxia was submitted for diagnosis. The postmortem examination revealed multifocal yellowish nodules in the pulmonary parenchyma and vegetative masses in the mitral and tricuspid valve of the heart. Both kidneys were severely enlarged, with multiple yellow nodules on the parenchyma. Histopathologically, pulmonary abscesses, vegetative endocarditis, suppurative glomerulonephritis, and fibrino-purulent arthritis were observed. The tiny β-hemolytic bacterial colonies were isolated from the lesions and identified as Arcanobacterium haemolyticum by the VITEK 2 system (bioMérieux, USA). This is the first documented report of an A. haemolyticum infection in a Holstein cow in Korea.

Fibrinopurulent peritonitis and abdominal abscesses associated with Streptococcus (S.) equi subsp. zooepidemicus is reported in a 1-year-old female thoroughbred horse. The horse died after showing 5-day history of the cold, severe abdominal distention, abdominal breathing, hyperthermia, anorexia, and loss of intestinal sound. At necropsy, several liters of turbid yellowish green fluid were seen in the abdominal cavity. Yellowish creamy and fibrinous or bloody materials were presented on the serosa of various abdominal organs that were intensively adhered with each other. Spleen and mesenteric lymph node were remarkably enlarged. Affected lobes of the lung showed severe congestion, hemorrhage and doughy consistency. Histologically, the lung showed hemorrhagic pneumonia with diffuse congestion and edema. Severe diffuse fibrinopurulent peritonitis with Gram-positive bacterial cocci and adjacent fibrosis were showed in the serosa of various abdominal organs such as liver, spleen, stomach, and intestine. And multifocal abscess pouches were presented in the granulation tissue of abdominal viscera. S. equi subsp. zooepidemicus was isolated from the peritoneal swab, abdominal organs, and lung. Hematogenous dissemination of bacteria from hemorrhagic pneumonia is proposed as the route of infection in this case.

목적: 뇌종양에서 자기공명 뇌혈류량지도(MR cerebral blood volume map)의 유용성을 평가하고자 하였다. 대상 및 방법: 15예의 두개강내 종괴(다형성 교모세포종 2예, 저등급 교종 3예, 뇌농양 2예, 뇌수막종 3예, 신경세포종 1예, 배아종 1예, 방사선괴사 1예, 전이암 1예) 에서 관류 MR영상을 수술전에 시행하였다. 환자의 평균연령은 42세였고(22-68), 남자 10명, 여자 5명이었다. MR영상기기는 1.5T unit(Signa, GE Medical Systems, Milwaukee, Wisconsin)를 사용하였다. 조영제 주입후 조영제의 일차 통과시 나타나는 자화율을 얻었다. (조영제는 최오의 MR 촬영시작후 10초부터 시작하여, 총량 15cc 의 Gadopentate dimeglumine(Magnevist)를 약 2ml/sec의 속도로 손으로 주입하였다). 각 환자마다 160초 동안 6 slice에서 slice당 80 image씩 총 480 image를 얻었으며 interleaved single shot gradient EPI기법을 사용하였다. 영상변수는 TR 2000ms, TE 50ms, FOV $240{\times}240mm,{\;}matrix{\;}size{\;}128{\times}128$, slice thickness/gap 5/ 2.5mm, flip angle $90^{\circ}$로 하였다. 얻은 영상데이터는 GE workstation으로 전송한 후, 자체적으로 개발한 software에 의해 각 kvoxel마다 시간경과에 따른 신호크기의 로그변화곡선(${\Delta}R2^{*}=-In(S/S_0$)의 적분값을 구하여 국소뇌혈류량(rCBV)영상을 구성하였다. 이의 시각적 해석을 용이하게 하기 위해 정상 뇌백질의 관류정도를 기준으로 하여 상대적인 RGB 색수치로 변환하여, color rCBV map을 얻었다. 관류의 정도와 조영증강정도를 중심으로 관류 MR 영상소견과 조직학적 소견을 관련지어 분석하였다. 결과: 조영증강 T1강조MR영상에서 환상조영증강을 보이는 다형성 교보세포종 2예에서는 변연부 외륜이 고관류를, 중심부의 괴사부위는 저관류로 나타났다. 저등급 교종은 경계가 불분명한 저관류부위로 보였다. 뇌농양 2예는 변연부 외륜이 경도의 고관류를, 중심부는 저관류로 나타났다. 뇌수막종은 미만성의 균일한 중등도 혹은 고도의 고관류로 보였으며, 임파종과 배아종은 경계가 명확한 저관류부위로 나타났다. 신경세포종은 종괴\ulcorner 일부에 중등도 혹은 고도의 고관류부위가 관찰되었고, 전이암은 다수병변중 일부에서 중등도의 고관류를 보였다. 방사선괴사는 저관류부위내에 국소적 고관류부위를 보였다. 결론: 관류 MR영상은 뇌종양의 관류상태를 비교적 잘 반영하며, 조직학적 특성을 예측하는데에 도움을 주 수 있을 것으로 기대된다. 뇌종야에서의 관류MR영상의 분명한 역할을 규명하기 위해서는 앞으로 더 많은 임상적 연구가 필요할 것으로 생각된다.
