뇌성마비는 뇌 발달시기중 초기의 장애로 인하여 운동기능과 자세의 이상 등을 초래하는 질환으로 임상적으로 여러 유형으로 나누어진다. 뇌성마비 환자중에서 MRI 상 롤란도야의 이상소견을 보이는 경우 특이한 임상적 특징을 나타낸다고 보고되어있다. 본 논문에서는 이들을 대상으로 하여 뇌 단일광자컴퓨터촬영에서 나타나는 뇌혈류 이상 소견과 MRI 소견, 그리고 임상양상들을 비교해보고자 하였다. 임상적으로 뇌성마비로 진단된 80여명의 환자중 MRI상 롤란도야에 저산소성 뇌질환의 소견을 보인 7명을 대상으로 하였다. 이들에게 5-10mCi의 Tc-99m-ECD를 정맥주사후 뇌 단일광자컴퓨터촬영을 하였다. 뇌 단일광자컴퓨터촬영상에서는 특히 뇌피질, 선조체, 시상, 뇌간 및 소뇌의 혈류이상 소견을 분석하였고, 이를 MRI 소견 및 임상증상과 비교하였다. 모든 환자들은 만삭 또는 만삭에 가깝게 태어났고, 주산기 아사가 여섯명의 환자에서 있었다. 임상적으로는 긴장성 사지마비로 나타났다. Tc-99m ECD를 이용한 뇌 단일광자 컴퓨터촬영상 롤란도야의 혈류감소는 모두에서 확연하게 나타났다 MRI상에서 롤란도야의 이상소견은 5명에서는 확실하게 나타났고, 2명에서는 의심되었다. MRI상에서 이상소견을 보인 것보다 더 광범위한 부분에서 뇌단일광자컴퓨터촬영상 이상소견이 보였다. 결론적으로, 롤란도야에서 이상소견을 보인 환자는 임상적, 구조적, 그리고 기능적으로 특이한 소견을 보였다. Tc-99m-ECD를 이용한 뇌 단일광자컴퓨터촬영은 매우 민감하게 반영하였고, MRI보다 뇌의 더 광범위한 부위에서 이상소견을 보였다.

세기관지를 침범하는 많은 질환들이 세기관지에 유사한 병리소견을 일으킴으로 이들의 원인, 병인, 진단을 위하여서는 임상 및 병리소견을 연관시킴이 거의 필수적이다. Small airways disease를 포함한 세기관지 질환의 병리소견 특히 호흡성 세기관지염, bronchiolitis obliterans organizing pneumonia, constrictive bronchiolitis obliterans 등에 대하여 중점적으로 기술하였다. BOOP은 어떤 급성 폐손상에 대한 비특이성 소견이며 조직병리적인 기술이다. 반면 Idiopathic BOOP은 COP와 동의어로써 특정한 질환이며 이의 주된 병리소견이 BOOP인 것으로 이해하는 것이 좋겠다. Constrictive bronchiolitis obliterans는 임상적으로나 병리학적으로 BOOP과는 다르다고 하겠다.

Background & Method : Bronchiolitis obliterans organizing pneumonia(BOOP) is a specific clinicopathologic condition characterized by chronic inflammatory interstitial infiltrates. Cryptogenic form of BOOP presents subacute clinical course of flu-like illness, such as cough, fever, dyspnea with exertion and other constitutional symptoms. Pathologically it shows the presence of granulation tissue filling the lumen of terminal and respiratory bronchioles, extending into distal airspaces. Recently, we reviewed 24 cases of idiopathic type of BOOP, 5 cases of our hospital and another 19 cases on Korean literatures, and compared with reviewed data from foreign literatures. Results : Mean age was 54 years old and there was female preponderance in domestic reports. Their common presenting symptoms were dyspnea and cough, and mean duration of illness was 41 days. On chest examination, inspiratory crackle was a common finding. The laboratory findings were nonspecific except hypoxemia. Lung function studies revealed restrictive defect or combined obstructive and restrictive pattern in most patients. Bilateral patchy and nonsegmental alveolar opacities constituted characterized radiographic finding, highlighted on high resolution computed tomogram. It showed a favorable prognosis with an excellent responsiveness to corticosteroid therapy. The clinical features and laboratory findings were similar between domestic and foreign cases except female preponderance in Korean cases. Conclusion : If the clinical course is atypical or pregressive under proper treatment, clinicians should reevaluate clinical features and radiographic findings under the consideration of BOOP. Tissue confirmation would be recommended for the definitive diagnosis of BOOP.

Purpose: The purpose of this study was to determine the correlation between the radiographic and clinical findings of massive rotator cuff tears. Materials and Methods: Forty-five diagnosed cases (35 patients) of massive rotator cuff tears were investigated in this study. Grade of arthritis in the massive rotator cuff tears was classified based on plain radiographs using the method of Hamada et al.. And we clinically evaluated cases using the UCLA scoring system. Results: No statistically significant correlation ($r_s$=0.220, p=0.151) was found between arthritis grades in massive rotator cuff tears and clinical features. Dominant arm involvement appeared to be related to a higher rate of surgical treatment and a lower UCLA score. Conclusion: In massive rotator cuff tear patients, radiographic findings of arthritis may not always correspond to clinical features relevant in daily life. Therefore, we suggest that treatment strategies should be carefully considered when considering treatment modalities.

The hippocampus is one of the most metabolically active regions of the brain; therefore, it may be affected by various acute disorders. This study aimed to introduce and categorize various acute conditions that can involve the hippocampus and explain the findings of MRI, especially diffusion-weighted imaging (DWI). Acute hippocampal disorders are divided into six categories: infection, inflammation, metabolic, ischemic, traumatic, and miscellaneous. In this study, patients were retrospectively reviewed based on clinical findings and MRI, especially DWI. All diseases had been confirmed clinically or pathologically. Many acute hippocampal disorders overlap with the clinical manifestations. Thus, it is necessary to categorize acute hippocampal lesions and understand their specific imaging findings for differential diagnosis.

Purpose : $Henoch-Sch\"{o}nlein$ purpura(HSP) is usually a self-limited disease with a good eventual outcome. The prognosis of HSP is mainly determined by the renal involvement. In this study, We evaluated children with biopsy-proven $Henoch-Sch\"{o}nlein$ purpura nephritis about the clinical outcome correlated with renal manifestation and morphologic findings. Methods : The clinical features, initial laboratory and pathologic findings, and clinical out-come were evaluated in 60 children with biopsy-proven $Henoch-Sch\"{o}nlein$ purpura nephritis at Yonsei University Severance Hospital during the period from Jan. 1990 to Dec. 2002. Results : The ratio of male to female patients was 1.2:1. The interval between the onset of $Henoch-Sch\"{o}nlein$ purpura and renal manifestation was less than 3 months in 81% of the patients. Initial renal manifestation was microscopic hematuria in 100% of patients, isolated hematuria in 15%, acute nephritic syndrome in 7%, nephrotic syndrome In 22% of patients. Renal manifestation correlated with clinical outcome. Grade II and III were the most common in histologic grades of ISKDC. Renal pathologic finding correlated with clinical outcome. Conclusion : Renal manifestation and pathologic findings correlated with the clinical out-come. It is necessary to evaluate the correlation between pathologic findings and treatment.

Backgroud: Traditionally, tuberculous pleurisy has been known to largely develop as primary tuberculosis. However, as the incidence of tuberculosis decrease, recent studies have shown reactivation tuberculosis has become the main cause of tuberculous pleurisy. Methods: 141 cases of tuberculous pleurisy, between January 2003 and February 2006, at the Dankook university hospital. were retrospectively studied. The patients were divided into primary and reactivation tuberculosis. based on the history and radiological characteristics, and the clinical, radiological characteristics at the time of diagnosis and residual pleural thickening after 6 month of chemotherapy were compared between the two groups. Results: 1. Of the 141 tuberculous pleurisy cases, in 135 it was possible to differentiate between primary and reactivation tuberculosis. 2. Of the 135 tuberculous pleurisy cases, 38 (28%) showed a primary tuberculosis pattern, and 98 (72%) showed a reactivation tuberculosis pattern. 3. There were no significant differences between primary and reactivation tuberculosis in relation to age, sex, duration of symptom, amount of pleural effusion, pleural fluid WBC, lymphocyte count, and level of protein, LDH and ADA at the time of diagnosis 4. 124 patients were followed for 6 months after diagnosis of tuberculous pleurisy, and there was no significant difference in the residual pleural thickening between primary and reactivation tuberculosis. Conclusion: In South Korea, a reactivation disease is currently a more common cause of tuberculous pleurisy than a primary disease. There was no difference in the clinical characteristics between primary and reactivation tuberculosis.

Background : Tumor size in lung cancer is not as good a prognostic factor for adenocarcinoma as it is for other types of lung cancer; therefore it is difficult to estimate the prognosis preoperative. However, there have recently been some reports on the radiologic findings correlating to the clinicopathologic prognostic factors in peripheral small adenocarcinoma of lung. We tried to evaluate the prognostic importance of High-Resolution CT (HRCT) findings of such adenoearcinoma, Material and Method: One houndred and seventy-six surgically resected small peripheral adenocarcinoma measuring 3 cm or less in greatest dimension were reviewed radiologically and clinicopathologically. Result: The patients with greater extent of ground-glass attenuation (GGA) had better clinico-pathological factors. The tumors with gross appearance of GGA or bubble-like shape showed better clinicopathological prognostic factors than scar-like or solid shape. Conclusion: HRCT findings of small peripheral adenocarcinomas of the lung correlated well with the histologic and clinical prognostic factors. We can predict the post-operative prognosis with the radiologic findings.
