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.

Purpose: To assess the utility of magnetic resonance(MR) cerebral blood volume (CBV) map in the evaluation of brain tumors. Materials and Methods: We performed perfusion MR imaing preoperatively in the consecutive IS patients with intracranial masses(3 meningiomas, 2 glioblastoma multiformes, 3 low grade gliomas, 1 lymphoma, 1 germinoma, 1 neurocytoma, 1 metastasis, 2 abscesses, 1 radionecrosis). The average age of the patients was 42 years (22yr -68yr), composed of 10 males and S females. All MR images were obtained at l.ST imager(Signa, CE Medical Systems, Milwaukee, Wisconsin). The regional CBV map was obtained on the theoretical basis of susceptibility difference induced by first pass circulation of contrast media. (contrast media: IScc of gadopentate dimeglumine, about 2ml/sec by hand, starting at 10 second after first baseline scan). For each patient, a total of 480 images (6 slices, 80 images/slice in 160 sec) were obtained by using gradient echo(CE) single shot echo-planar image(EPI) sequence (TR 2000ms, TE SOms, flip angle $90^{\circ}$, FOV $240{\times}240mm,{\;}matrix{\;}128{\times}128$, slice-thick/gap S/2.S). After data collection, the raw data were transferred to CE workstation and rCBV maps were generated from the numerical integration of ${\Delta}R2^{*} on a voxel by voxel basis, with home made software (${\Delta}R2^{*}=-ln (S/SO)/TE). For easy visual interpretation, relative RCB color coding with reference to the normal white matter was applied and color rCBV maps were obtained. The findings of perfusion MR image were retrospectively correlated with Cd-enhanced images with focus on the degree and extent of perfusion and contrast enhancement. Results: Two cases of glioblastoma multiforme with rim enhancement on Cd-enhanced Tl weighted image showed increased perfusion in the peripheral rim and decreased perfusion in the central necrosis portion. The low grade gliomas appeared as a low perfusion area with poorly defined margin. In 2 cases of brain abscess, the degree of perfusion was similar to that of the normal white matter in the peripheral enhancing rim and was low in the central portion. All meningiomas showed diffuse homogeneous increased perfusion of moderate or high degree. One each of lymphoma and germinoma showed homogenously decreased perfusion with well defined margin. The central neurocytoma showed multifocal increased perfusion areas of moderate or high degree. A few nodules of the multiple metastasis showed increased perfusion of moderate degree. One radionecrosis revealed multiple foci of increased perfusion within the area of decreased perfusion. Conclusion: The rCBV map appears to correlate well with the perfusion state of brain tumor, and may be helpful in discrimination between low grade and high grade gliomas. The further study is needed to clarify the role of perfusion MR image in the evaluation of brain tumor.
