Descending nectorizing mediastinitis (DNM). represents a virulent form of mediastinal infection requiring prompt diagnosis and treatment to reduce the high morbidity mortality associated with this disease. Intr. avenous broad-spectrum antibiotic therapy alone is not efficient without adequate surgical drainage of the cervical and mediastinal collections, extensive debridement and excision of necrotic tissue, and wide mediastino-pleural irrigation. A 38-year-old man admitted via emergency room with painful left neck swelling and uncontrolled high fever. Chest computed tomogram showed left paratracheal abscess descending into the superior and anterior mediastinum. Transcervical mediastinal drainage was performed with 26 Fr. chest tube and left paratracheal drainage was performed with Penrose drain in urgency. Culture and sensitivity test grew Yeast. The drains removed via gradually shortening on day 39 after surgery.

An 11 year-old intact female Yorkshire Terrier weighing 3.5 kg was presented with the complain of having a perineal mass, fecal incontinence and tenesmus. Physical examination revealed reducible bilateral ventral perineal mass, enlarged mammary gland and vaginal discharge. Bilateral ventral perineal hernia (BVPH) and pyometra were diagnosed based on the clinical and radiographic findings. Ovariohysterectomy was performed after general anaesthesia to treat pyometra. The BVPH was repaired by herniorrhaphy with semitendinosus muscle transposition along with colopexy and cystopexy. The postoperative radiographs and CT revealed a good correction of the BVPH. The patient showed good activity after 10 days and no complications were observed during a one year follow up period. BVPH can be successfully surgically managed by herniorrhaphy with semitendinosus muscle transposition along with cystopexy and colopexy in the dog.

A sixty nine-year-old mate patient was admitted with a chief complaint of exertional dyspnea. Lung perfusion scan revealed total perfusion defect of the of left lung and CT anglography showed the ab- rupt cutoff left pulmonary artery. He denied of trauma history, previous lower leg symptom and sign, or any embolic history. With the impression of chronic pulmonary thromboembolism of unknown etiology, operation was done under the cardiopulmonary bypass through a median sternotomy. After main pulmonary artery clamping and pulmonary arteriotomy, thromboembolectomy was done. Postoperative lung perfusion scan and CT angiography showed near normal left pulmonary blood flow. The patient was discharged on the postoperative 9th day without any postoperative complication.

A 60-year-old female entered the emergency unit with a chief complaint of hemoptysis. Based on the computer tomographic image analysis of the chest, the patient was diagnosed as having an intralobar pulmonary sequestration that accompanied a hemothorax, and the hemothorax was do to the rupture of a pseudocyst. Pulmonary lobectomy of the left lower lobe and primary closure of an aberrant artery were both performed as an emergency operation. After one week following the operation, the patient was discharged without any postoperative complications.

The purpose of this study was to determine and compare prostate size using ultrasound and computed tomography (CT). The prostate gland was evaluated in eight normal Beagle dogs. Length, depth, and width of the prostate gland were measured by ultrasound and volume of the prostate was obtained from the two ellipsoid formula (US1, US2). Height, length, width, area, and volume of the prostate gland were measured by CT. Ratios of prostatic height, length, and width to the sixth lumbar vertebral body length were calculated. There was no significant difference between the US1 and US2 method, and between US2 and CT method, respectively. The prostatic volume calculated by US1 method was significantly lower than those with CT (p=0.029). The Upper limits of ratios of prostate length, height, and width to the length of the sixth lumbar vertebra were 1.3, 1.1, and 1.7, respectively. Among these prostate dimensions, prostate length and height could be a useful index in estimating prostate size regardless of body weight.

Traditionally, cervical interventions have been performed under fluoroscopy. But radiation exposure is the major concern when obtaining fluoroscopic images and even under real-time fluoroscopy with contrast media or CT guidance, some cases of serious spinal cord injuries, cerebellar and brain stem infarction have been reported by unintentional intra-arterial injections especially during the transforaminal root blocks. Recently, the use of ultrasound-guided cervical interventions have increased. Ultrasound offers visualization of soft tissues including major neurovascular structures and also allows to observe the spread of injectant materials around the target structure. Ultrasound is radiation free, easy to use and the image can be performed continuously while the injectant is visualized in real-time, increasing the precision of injection. Importantly, ultrasound allows visualization of major nerves and vessels and thus leads to improve safety of cervical interventions by decreasing the incidence of injury or injection into nearby vasculature. We therefore reviewed to investigate the feasibility of performing cervical interventions under real-time ultrasound guidance.

Primary malignant melanoma of the lung is extremely rare. A 46-year-old lady was admitted with two month history of dry cough and blood-tinged sputum. Chest CT showed 4.5 $\times$ 5.0 cm sized mass at the right lower lobe. Repeated bronchoscopic and percutaneous biopsies showed no definite diagnosis. Preoperative evaluations revealed no systemic metastais. So, we tried the surgical approach. Right lower lobectomy and lymph node dissection was done. The mass and lymph node were confirmed as primary malignant melanoma. The patient presented with right hemiparesis 40 days after operation. Brain MRI showed 1.5$\times$2.0 cm sized mass lesion on the left parietal lobe. Mass excision was done. However, she expired 8 months later.

Inflammatory sinonasal disease was diagnosed in five dogs and two cats with clinical signs of nasal discharge and epistaxis. Survey radiography and CT were performed in all of patients. CT scan of the rostral cranium was performed with a thickness of 2 or 5 mm. Nasal cytology and culture from nasal smear were performed immediately after CT examination. Remarkable increase of opacity in the nasal cavities and frontal sinuses was observed in only 3 cases. On CT images, the cavitating lesions were isodense in nasal cavity (7 cases), frontal sinuses (3 cases), and nasopharynx (2 cases) with destruction of the nasal septum (4 cases), maxillary turbinates (5 cases), maxilla (3 cases), and hard palate (3 cases). The lesions were enhanced after intravenous contrast administration in 5 cases and were not enhanced in 2 cases. Inflammatory cells were observed in nasal cytology. Most of the cultures from nasal smear were bacteria. CT is useful to diagnose sinonasal disease and is more accurate in demonstrating the extent and character of lesions of nasal cavity than radiography.

본 논문에서는 영상 포렌식에 관한 내용을 절도죄 중 소매치기를 대상으로 연구를 수행하였다. 절도죄에서 소매치기는 대부분 사람이 많은 곳에서 사람이 서있는 경우와 앉아있는 경우에 발생한다. 또한 술에 만취해서 누워있는 경우에도 발생한다. 본 눈문에서는 이러한 소매치기의 특징을 파악하여 CCTV로 촬영한 영상에서 범죄를 가려내어 증거 자료로 제출 하고자 한다.

Acute abdominal Aortic occlusion is rare but it is a vascular emergency with high mortality and morbidity. There­fore, delay in diagnosis can have severe impact on the prognosis. A 60-year-old women complained of paresthesia, paralysis, and severe pain in bilateral lower extremities on 13th day after open heart surgery for mitral stenosis, atrial fibrillation, coronary arterial stenosis, tricuspid regurgitation, and atrial septal defect. Her skin was mottled and cool from the umbilicus to the feet, and there were no palpable pulses in the lower exteremities. We diagnosed an acute abdominal aortic occlusion using the Multi-Detector Row Spiral Computed Tomography and successfully treated the problem with emergent thrombo-embolectomy and Aortobifemoral bypass.
