Glomus tumors of the lung are rare benign neoplasm, originating from modified smooth muscle cells. The patients are usually presented with no or non-specific symptoms such as cough, dyspnea or hemoptysis. Although surgical treatment is considered as the treatment of choice, the endobronchial therapy can be applied to the patients who are unfit for surgical excision. Herein, we describe two rare cases of glomus tumor originated at large airway (trachea and main bronchus) without respiratory symptoms and review their characteristic radiologic, macroscopic and pathological features.

Disorders related to the cervical spine can present a variety of signs and symptoms because of the many tissues and systems associated with this region. Therefore the challenge for the clinician is to organize the information from examination into a treatment plan that addresses the potential influences of the problem. the examination process should gather pertinent information from the patients, relating the pain pattern resulting loss of function. Our patients' X-rays showed absence of any abnormalities except loss of curvature. We therefore concluded that the main cause of posterior neck and shoulder pain was caused by muscle spasm, not cervical disc herniation not degenerative change.

In general, the long head of the biceps brachii originates from the superior glenoid labrum and the supraglenoid tubercle, crosses the rotator cuff interval, and extends into the bicipital groove. However, rare anatomic variations of the origins of the long head have been reported in the past. In this report, we review the clinical history, radiologic findings, and arthroscopic identifications of 3 anatomic variants of the biceps tendon long head. As the detection of long head of biceps tendon pathology during preoperative radiologic assessment can be difficult without prior knowledge, surgeons should be aware of such possible anatomic variations.

Infectious and inflammatory bone diseases include a wide range of disease process, depending on the patient's age, location of infection, various causative organisms, duration from symtom onset, accompanied fracture or prior surgery, prosthesis insertion, and underlying systemic disease such as diabetes, etc. Bone infection may induce massive destruction of bones and joints, results in functional reduction and disability. The key to successful management is early diagnosis and proper treatment. Various radionuclide imaging methods including three phase bone scan, Ga-67 scan, WBC scan, and combined imaging techniques such as bone/Ga-67 scan, WBC/bone marrow scan add complementary role to the radiologic imaging modalities including plain radiography, CT and MRI. F-18 FDG PET imaging also has recently been introduced in diagnosis of infected prosthesis and chronic active osteomyelitis. Selection of proper nuclear medicine imaging method will improve the diagnostic accuracy of infections and inflammatory bone diseases, based on understading of pathogenesis and radiologic imaging findings.

We report two cases of cleidocranial dysplasia, which was managed without significant craniofacial osteotomy. A mother and daughter, both of normal intelligence, presented with central forehead depression, mid-face hypoplasia, and blepharoptosis. The fact that they have an identically deformed face implied a genetic basis. In both patients, radiologic evaluation revealed the underdeveloped maxilla, persistent fontanelle opening, and cleidal aplasia. Clinical findings and radiologic studies were consistent with the diagnosis of cleidocranial dysplasia. Both patients underwent forehead plasty via bicoronal approach, augmentation rhinoplasty using tip plasty, and epicanthoplasty. In addition, the mother underwent malar augmentation using Medpor implantation and reduction genioplasty. The patients did not experience any postoperative complication and remained satisfied with the operation at 6-year follow-up.

최근 5년간의 소아의 복부종괴 23예를 발생빈도, 부위 및 방사선학적 소견을 중심으로 비교분석하여 다음과 같은 결론을 얻었다. 1. 전체 23예중 신경아세포종이 6예로 가장 많았고 그 다음이 Wilms 종양 5예, 담도낭종, 난소종양, 수신종 등의 순위였다. 2. 발생연령별로 분석해 본 결과 6세 이하가 78%(14예)를 차지했고 특히 후복강 종양은 6세 이하에 집중되어 있었다. 3. 부위별로는 후복강 종양이 60%(14예)로 가장 많았다. 4. 방사선학적 소견을 분석하여 본 결과 1) 단순 복부촬영상 신경아세포종의 50%에서 특징적인 석회와 음영을 볼 수 있었고 후복강 종양의 대부분에서 비특이적인 석회화 음영을 볼 수 있었다. 2) 초음파 소견상 저에코, 고에코 또는 혼합에코 등의 종괴 내부성상을 알 수 있었으나 종괴의 정확한 해부학적 위치를 파악할 수 없는 경우가 많았다. 3) 경정맥 신우 조영촬영상 신우신배의 비정상적인 소견과 신장의 전위 소견으로부터 신장내 종양과 신장의 다른 부위의 종양을 구분할 수 있었다. 4) 전산화 단층촬영상 종괴 내부의 성상뿐만 아니라 종괴의 해부학적인 위치, 주위 구조와의 관계, 임파절이나 다른 부위로의 전이유무를 알 수 있었다.

There are several respiratory diseases that show chronic granulomatous inflammation for the histologic finding. Among them, sarcoidosis and tuberculosis are not easy to differentiate when the clinical and radiological features present similar patterns. The increasing incidence of nontuberculous mycobacteria pulmonary disease is making it more difficult for clinicians to arrive at a proper diagnosis. A 69 year old male patient visited our hospital with chronic cough as his chief compliant. His radiologic findings were multiple enlarged mediastinal lymphadenpathies with innumerable micronodules and multiple patch infiltrations. The spleen biopsy finding showed chronic granulomatous inflammation, and Mycobacterium avium was identified on the bronchoscopic culture. Because of these findings, we treated him with drugs for nontuberculous mycobacteria disease other than sarcoidosis. However, during the treatment, his symptoms and radiological features became aggravated. Thus, we reviewed the radiologic and pathologic findings and decided to treat him with steroid, which relieved his symptoms and improved the radiologic findings. We report here on a case of sarcoidosis that was initially misdiagnosed as nontuberculous mycobacteria pulmonary disease.

Objective : Object : A 7-year retrospective clinical and MRI study was reviewed to evaluate the characteristics of pineal cyst. We evaluated results of clinical and radiologic change of pineal cyst during follow up period. Patients and Methods : From 1992 to 1999, 50 patients with pineal cyst were visited for evaluation. Follow up clinical information was obtained from patients or clinical record through phone conversation. also radiologic findi-ngs of pineal cyst in mid-sagittal MRI were reviewed in detail. Results : Pineal cysts were usually asymptomatic and detected incidentally during evaluation of other diseases. Sagittal MRI is the most useful diagnostic test. The radiologic findings of pineal cyst were isointensity on T1WI comared to CSF and slightly high signal intensity on T2WI. Cyst wall was variably enhanced on Gad-enhanced T1WI. The average size of cyst was $13.9{\times}13.0mm$. The pineal cyst was classified into five groups according to previous report. Long term behavior of these lesions are not apparent, but in our study they showed no specific changes in clinical and radiological aspects during 25 months. Conclusion : Although long-term follow up results are needed, the pineal cyst are considered as normal variants. In our 25 months follow up results, there was no rapid change of cyst both clinically and radiologically. Therefore, frequent radiologic evaluation seems unnecessary except type III pineal cyst.

The introduction of high-resolution CT (HRCT) in recent years has improved the ability of radiologists to detect and characterize the diffuse infiltrative lung disease (DILD). The detection and diagnosis of diffuse lung disease using HRCT are based on the recognition of specific abnormal findings. In this article, pattern recognition of HRCT findings is reviewed in the differential diagnosis of diffuse infiltrative lung disease. In general, HRCT findings of lung disease can be classified into four categories based on their appearances. These categories consist of (1) nodules and nodular opacities, (2) linear and reticular opacities, (3) increased lung opacity, and (4) decreased lung opacity, including cystic lesions.

We report 4 cases of malignant thymoma which were composed of 2 cases of invasive thymoma and 2 cases of thymic carcinoma. The cytologic findings of invasive thymoma were similar to those of benign thymoma. The distinctive cytologic features of thymic carcinoma were necrotic background, irregular clusters and individually scattered arrangement of anaplastic epithelial cells, and some scattered mature small lymphocytes. These findings may be found in the Hodgkin's lymphoma, seminoma, and metastatic squamous ceil carcinoma, undifferentiated carcinoma, and large ceil carcinoma of the lung. But, the feature of irregular clustering of anaplastic epithelial cell haying scanty cytoplasm was different from Hodgkin's lymphoma and seminoma. Clinical and radiologic findings as well as cytologic finding were helpful in differential diagnosis of thymic carcinoma from metastatic carcinoma.
