Dural injury during spinal surgery can subsequently give rise to a remote cerebellar hemorrhage (RCH). Although the incidence of such injury is low, the resulting hemorrhage can be life threatening. The mechanism underlying the formation of the hemorrhage is not known, but it is mostly thought to develop after venous infarction. Cerebellar mutism (CM) is a frequent complication of posterior fossa operations in children, but it is rarely seen in adults. The development of CM after an RCH has not been described. We describe the case of a 65-year old female who lost cerebrospinal fluid after inadvertent opening of the dura during surgery. Computerized tomography performed when the patient became unable to speak revealed a bilateral cerebellar hemorrhage.

In this paper, as a new measurement method to estimate the change of material condition, the simplified ultrasonic CT system, which uses the information of three directions, that is, $90^{\circ}$, $+45^{\circ}C$and $-45^{\circ}C$ about inspection plane is proposed. Use of simplified CT system has two merits: Firstly, the measurement time is very short compared with general CT. Secondly, it can detect sensitively small defect in vertical or slant direction about inspection plane because the obtained image is CT image calculated from three directions. From these merits, this method can be considered as an effective method to evaluate material conditions. The basic performance of the proposed method was confirmed through several specimens with several simple defects. In order to confirm the applicability of actual NDT, several kinds of welded specimens are investigated. The result showed that the CT image obtained had good agreement with actual defect of specimens.

Headache after epidural block is the most frequent result of an unintentional dural puncture. This form of headache is usually caused by cerebrospinal fluid leakage through the dural puncture site. Another proposed cause of postdural puncture headache is the unintentional injection of air into the subarachnoid space. We experienced a case of severe headache with a patient after lumbar epidural block and discovered air in the intracranial subarachnoid space(pneumocephalus) with the aid of brain computerized tomography.

Liver abscess in children is rare in developed countries; the incidence is 25 per 100,000 admissions in USA. Common complications are pleural effusion, empyema, pneumonitis, hepatopleural or hepatobronchial fistula, intraperitoneal or intrapericardiac rupture, septic shock, cerebral amebiasis, etc. These complications may lead to death if the management is delayed. However, recent management results in a mortality of less than 15%. We report a case of liver abscess in a child. He manifested with fever and abdominal pain in the right upper quadrant. On computerized tomography scans, multiple cystic lesions were seen in both lobes of the liver and were 5 to 55 mm in size. In laboratory findings, neutrophilic leukocytosis, peripheral eosinophila, elevated values of ESR, C-reactive protein, and elevated serum AST, ALT, ALP and GGT were detected. Furthermore, we determined the organisms in the blood culture and serum. Blood culture was positive for Streptococcus spp., and amebic indirect hemagglutination antibody titer was increased to 1:512.

Purpose : The purpose of the study was to examine lumbar pain through literature reviews about herniated intervertebral disc (HIVD). Methods : Diagnosis was made by patient's history, physical examination, simple radiography, myelography, spinal computerized tomography, electromyography, somatosensory evoked potential, etc. Results : There are two treatment modalities, one is conservative and the other is operative. About 90% of patients with HIVD have been recovered only by conservative treatment and therapeutic exercise was the most effective one among these conservative treatments. Conclusion : We consider HIVD can be treated with therapeutic exercise which can correct muscular imbalance and facet joint problems and make the degenerative process of intervertebral disc slower.

The patient was 22-year old male who had been suffered from labored breathing. Computerized tomography, tracheoscopy, tracheogram disclosed tracheal obstruction by external mass compression on Tl level, which ranged 4.Oem in the length and approximately 4mm in diameter on tracheogram. Under the local anesthesia, tracheostomy was done to prevent intraoperative airway obstruction. And general anesthesia, low collar incision 8z extended median sternotomy was made and nearly total thyroidectomy was performed. After the circumferential resection of the obstructed segment approximately 4cm in length[7 tracheal rings], direct end-to-end anastomosis of trachea was performed. Postoperatively, the patient`s neck was maintained in flexion state to reduce tension of anastomotic site. Postoperatively. medical therapy[Comthyroid k Calcium lactate] and radiotherapy were done. At present, 2-months after operation, he lives well.

The carbon fiber has low x-ray absorption property and high stiffness. This is the reason why many CT(Computed Tomography) manufacturer use carbon fiber in couch tabletop for CT scanner. In this paper, we design and make the couch tabletop made of carbon fiber composite, and verify the validity in CT scanner. In designing the couch tabletop, to determine the aluminum equivalent thickness of couch tabletop, we evaluate X-ray the transmissivity of aluminum and carbon plate in 80-120kVp X-ray energy range. And we perform structural analysis and mechanical design using determined thickness of carbon sheet. In conclusion, it was evaluated that manufactured couch tabletop satisfies X-ray transmissivity and mechanical requirements in CT scanner.

Gastric lipomatosis is an extremely rare condition. We present a case of a 69-year-old woman admitted with epigastric soreness. Computerized tomography (CT) revealed extrinsically compressing, fat-containing mass lesions on the entire gastric wall of the antrum and body except for the lesser curvature. A subtotal gastrectomy was performed. Pathology findings confirmed a gastric lipomatosis with multiple gastric ulcerations and extensive disruptions of the muscular layers. This case and reports of other gastric lipomatosis cases indicate that CT should be used to characterize large submucosal masses because CT can show the specific nature and extent of the disease. We believe that surgical treatment is the most appropriate treatment for symptomatic gastric lipomatosis that shows extensive gastric involvement, or when there are multiple gastric lipomas.

The authors present a case of 68-year-old woman who underwent resection of a metastatic adenocarcinoma in the left parietooccipital area. The intraoperative course was uneventful; however, after closure of the scalp incision, increased bleeding from the suture line was noted. A computerized tomography scan that was performed immediately after operation revealed acute epidural hemorrhage with mass effect under the bone flap. The patient developed disseminated intravascular coagulation and immediate re-exploration was performed. This patient was successfully treated owing to early recognition of the condition and immediate treatment with transfusion. Neurosurgeons should be alert that hypercoagulabe state is common in cancer patients and consumptive coagulopathy can occur after resection of metastatic brain tumor.

Maxillary lateral incisors usually exhibit a single root with a single canal. However, maxillary lateral incisor teeth with unusual morphology of root canal system are frequently reported. These cases of variable root canal anatomy can be treated well by nonsurgical endodontic methods. A detailed description of root canal morphology is fundamental for successful endodontic treatment. Treatment using an operating microscope, radiographs from different angles, and cone-beam computerized tomography (CBCT) can produce more predictable endodontic outcomes.
