  • Purpose: Abdominal and pelvic computed tomography (APCT) is frequently used as a diagnostic tool in trauma patients. However, trauma unrelated, incidental findings are frequently encountered. The aim of this study was to determine the prevalences of incidental findings on APCT scans in trauma patients. Methods: The archived records of 801 trauma patients treated from January 2013 to December 2015 were reviewed retrospectively. Six hundred and forty of these patients underwent contrast enhanced APCT in an emergency department and were included in this study, and 205 (32.1%) of these patients had incidental findings. These findings were divided into two categories: category I, meaning a radiological benign finding not requiring further evaluation or follow-up, and category II, requiring further evaluation and follow-up. Results: One hundred and sixty (24.8%) patients were allocated to category I and 45 (7.2%) to category II. The most frequent incidental findings were discovered in kidneys (34.6%), followed by liver (28.8%), and gallbladder (15.6%). The most frequent finding in category I was a benign cyst (60.1%), followed by a simple stone (15.6%), and hemangioma (11.9%). Adenomyomatosis of the gallbladder (17.8%) was the most common lesion in category II, followed by atypical mass (15.6%), complicated stone (15.6%) and cystic neoplasm (15.6%). Conclusion: The prevalence of an incidental finding on APCT scans was 32.1%. Although category II lesions were not common in trauma patients, these findings should be communicated to patients, and when necessary referred to a primary care physician. Systems are required for producing appropriate discharge summaries and informing patients about the implications of incidental findings.

  • The odontogenic keratocyst(OKC) was used of term and described some of clinical, radiological and microscopic features by Philipsen 1956. The microscopic finding of OKC is characterized by the production of keratin, Which sometimes fills the lumen and thinning of epithelium of cyst. The most clinical importance of OKC is its extraordinary recurrence rate owing to the incomplete removal of the cyst wall. The final diagnosis of OKC should be evaluated by histologic findings and follow-up of any case of OKC with annual roentgenograms and clinical evaluations is essential for at least five years after surgery. This article is report of 2 cases of large OKC involved both molar portion and symphysis of mandible with facial asymmetry, severe bone destruction and paresthesia of lower lip on clinically, roentgenographically. By the postoperative findings the patients showed normal regeneration of bone defect area without recurrence signs by panorama films after surgery.

  • Purpose: To evaluate the clinical validity of percutaneous screw fixation in Maisonneuve fracture. Material and Methods: Out of 5 Maisonneuve fracture patients hospitalized in the department of orthopedic surgery of Seigang hospital from February 1995 to May 1998, 4 patients were treated with percutaneous screw fixation and 1 patient was treated with percutaneous screw fixation and repair of deltoid ligament altogether. The results were evaluated on the clinical and radiological finding. Results: In all cases, the range of motion of ankle joint was normal, the complication such as postoperative pain and post-traumatic arthritis were not found. Widening of medial clear space or talar shift were not found in the follow up X-ray and tibiofibular distance, compared with normal ankle joint was same on follow up CT. Conclusion: Percutaneous screw fixation is simple, less invasive and more effective method in the treatment of Maisonneuve fracture.

  • Cystic Meningiomas are rare tumor. There is a clear prevalance in infants, according for $10{\sim}19%$ of all intracranial meningiomas in this age group, compared with only $2{\sim}4%$ in adults. But, reports of cystic meningioma have been increased in frequency since the introduction of computed tomography[CT] and magnetic resonance image[MRI]. Authors report two cases of cystic meningioma in adults. Radiological finding showed extraaxial mass with cystic component. Authors performed total surgical resection of the tumor mass and of the entire cystic component with cystic wall in both patients. Postoperative histopathological diagnosis of the tumor mass was a transitional meningioma in both patients. Both patients showed favorable prognosis and no recurrence findings in follow up MRI.

  • 1. Objectives This study evaluates the effect of oriental medical treatment on a chronic sinusitis patient. 2. Methods The patient was teated with acupuncture, nasal cavity irrigation, and Yangdokbackho-tang(陽毒白虎湯). Previous western medical methods were excluded in order to provide therapeutic methods different from pre-existing ones because we needed different, long-term treatment plan from previous treatment. We applied acupuncture 15 times during treatment period and instructed the patient to carry out nasal cavity irrigation at home. 3. Results & Conclusions Combined application of oriental treatment including administration of Yangdokbackho-tang and nasal irrigation showed remarkable clinical effects on symptom, physical examination and radiological finding.

  • Cerebral ischemia results in neuronal changes in remote areas that have fiber connections with the ischemic area. The aim of this study was to investigate the nigral changes by examining the correlation between the apparent diffusion coefficient (ADC) and the tissue structure. Sprague-Dawley rats were subjected to middle cerebral artery occlusion. Four days after the occlusion, when T2-weighted images revealed the presence of an area of high signal intensity in the ipsilateral substantia nigra, and the ADCs were calculated and imaged. Histopathologic examination by both light and electron microscopy was performed on day 4 after surgery. This finding was consistent with the high signal intensity seen on T2-weighted and diffusion-weighted images, as well as with the ADC reduction, but we did not expect to observe uniform ADC reduction attributable mainly to astrocytic swelling in the perivascular end-feet.

  • Central neurocytoma is a rare, well-differentiated neuronal tumor and is usually located in the lateral or third ventricle of young adults. The occurrence of an intraventricular tumor with a characterisitic magnetic resonance image findings including isointense signal in T1-weighted images, the presence of a cystic component, small signal-void areas due to calcification, heterogenous and hyperintense "bubbly" appearance in T2-weighted images in a young patient should suggest preoperatively the diagnosis of central neurocytoma. The typical immunohistochemical finding, positivity for synaptophysin, is the main pathological feature. We experienced two cases of central neurocytomas with typical radiological and histopathological findings. We expect growth arrest of these cases by subtotal removal to avoid postoperative neurologic deficit followed by radiation therapy.

  • Pilocytic astrocytomas (PAs) are World Heath Organization Grade I tumors and are most common in children. PA calcification is not a common finding and has been reported more frequently in the optic nerve, hypothalamic/thalamus and superficially located cerebral tumors. We present a cerebellar PA in a 3-year-old male patient with cystic components and massive calcification areas. The residual tumor grew rapidly after the first operation, and the patient was operated on again. A histopathological examination revealed polar spongioblastoma-like cells. Massive calcification is not a common feature in PAs and can lead to difficulties in radiological and pathological differential diagnoses.

  • The clinical and radiographic findings of lung cancer have been well established many journals. Even if the radiographic findings of lung cancer show a typical pattern, the specific cell type of lung cancer sometimes needs to be determined prior to a pathological diagnosis. For example, the usual finding of a squamous cell carcinoma is similar to other cancer types such as an adenocarcinoma or a small cell carcinoma but with a lower incidence. Therefore, it should not be used to make a diagnosis of the cell type prior to a pathological diagnosis. Many unusual findings of lung cancer, so called atypical pattern have been reported, but atypical findings are widely accepted. The more important thing is not to diagnose a specific cell type of cancer but to differentiate it from other benign conditions such as tuberculosis, fungal infections or organizing pneumonia. This paper presents typical information of the cell type of lung cancer along with the atypical radiographic findings.
