Early detection of skeletal disorders was very important role in establishing therapeutic modality and prevention of complications. Since Tc-99m-phosphates derivatives used in bone scan agent, remarkable improvement was noted in effectiveness, cost, radiation hazard to patient and image quality than previously used agents such as strontium or fluoride. Bone scan with Tc-99m-MDP was done in 155 cases for early diagnosis of skeletal disorders at Severance Hospital, College of Medicine, Yonsei University from August, 1980 to May, 1982 were analyzed both clinically and radiologically, and the following results were obtained. l. Among 19 cases of avascular necrosis, positive cases were 17 (89.5%) in bone scan and 6(31.6%) in X-ray. Positive pattern could be classified into 3 types and the radionuclide uptake in the femoral head was decreased in 3 cases which was negative in X-ray and duration of their symptoms was within 4 months. 2. Fifteen among 17 hip fractures or dislocations were positive in bone scan. In 12 (80.0%) among 15 cases, complications were revealed and positive cases in X-ray were 7(58.3%), which were all positive in bone scan. 3. In 20 bone scans for early diagnosis of acute osteomyelitis, positive in bone scan were 17 and 14 (82.4%) of 17 cases were finally diagnosed as acute osteomyelitis. Among 15 cases diagnosed as acute osteomyelitis, positive in X-ray were 8(53.3%) and sensitivity of acute osteomyelitis in bone scan was 93.3%. 4. In 25 cases of the suspected infection of the joint, 15 were positive in bone scan and among them, cases diagnosed as pyogenic arthritis were 12 (80.0%) and positive in X-ray were 2 (16.7%). Only one of 10 cases of transient synovitis of the hip joint was positive in bone scan. 5. In rheumatoid arthritis, 13 of 15 cases were positive in bone scan and 10 among them were revealed the diffuse uptake of the radionuclide in the joint. In degenerative arthritis, 7 of 8 cases were positive in bone scan and they were revealed the focal uptake of the radionuclide in the same site where the bone was changed in x-ray. 6. Among 28 cases showed spine fracture in X-ray after trauma, 15 (53.6%) were positive in bone scan. In spine fracture, it was difficult to differentiate fresh fracture from old fracture with bone scan. The positive duration of bone scen in fracture of weight bearing bone was longer than in spine fracture. Rib fracture which was not found in X-ray could be diagnosed with bone scan.

Generalized plane xanthoma is less common and usually involves the eyelids, lateral side of the neck, upper trunk, and extremities. Lesions, however, may appear on any portion of the body. Cutaneous xanthomas may occur in hyperlipidemic and in normolipidemic states. Generalized normolipidemic plane xanthoma is often associated with multiple myeloma, other reticulo-endothelial malignancies and monoclonal gammopathy with unknown significance(MGUS). We wish to report two eases of generalized plane xanthoma associated with IgG monoclonal gammopathy of unknown significance.

We report a false positive case of I-131 scan due to a sialolithiasis in right submandibular gland. I-131 images showed not only remnant thyroid tissues and functional metastases in the anterior neck but also a hot uptake near right submandibular gland. We confirmed the sialolithiasis by radiologic studies. Sialolithiasis should be regarded as a false positive cause when I-131 scan shows a hot spot near salivary bed.

Kimura's disease is an uncommon, chronic inflammatory disorder of unknown etiology that is seen in an endemic form in the Orient. It usually presents as a mass in the subcutaneous tissue of the head and neck region or the major salivary glands, and is often associated with a regional lymphadenopathy. The patients have peripheral blood eosinophilia and elevated IgE levels but are otherwise usually healthy. We encountered the case of a 33-year-old man who had a soft tissue mass in his left distal arm which was diagnosed as being Kimura's disease.

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.

Bottoming out is the term used to describe the inferior displacement of a breast implant after breast augmentation that results in increased distance between the nipple areolar complex and the inframammary fold. Conventional techniques for correcting bottoming out involve capsulectomy and capsulorrhaphy via an inframammary fold incision that is prone to cause large scar and increases the patient's burden. However, using an endoscopic approach via the axilla, we are able to correct bottoming out, resulting in a smaller scar and shorter recovery time. In this article, we present a novel and simple method to correct bottoming out using endoscopy and electrocauterization.

Myocardial scintigraphy is a widely used noninvasive procedure with high sensitivity for the detection of patients with suspected coronary artery disease. The purpose of this study was to determine the prognostic value of a normal myocardial scintigraphy in 292 patients (150 males, 142 females, mean age 53+/-12 years) with chest pain who were followed from 7 to 58 (mean 25) months. Myocardial SPECT was performed with Tc-99m MIBI in 173 patients, with Tc-99m tetrofosmin in 74 patients and with T1-201 in 45 patients. During the follow-up period, there were 2 cardiac deaths and 2 nonfatal myocardial infarctions resulting in cardiac event rate of 1.37% (0.66% per year). The cardiac event rate was not different in patients with angiographically normal coronary arteries (1/30, 3.3%) and in those who had significant coronary a disease (2/27, 7.4%) (p=0.60). In conclusion, patients with chest pain and normal myocardial scintigraphy have a low cardiac event rate, and there was no significant difference of cardiac event rates between patients with normal and abnormal coronary angiograms.

It has been shown that both rest and stress myocardial perfusion imagings with technetium agents can be performed on the same day using two different doses injected within few hours. The purpose of this study was to compare the two protocols (stress-rest and rest-stress) in detecting coronary artery diseases. One hundred and sixty patients (101 males, 59 females, mean age 57+/-9 years) and 120 patients (79 males, 41 females, mean age 59+/-10 years) underwent stress-rest myocardial perfusion SPECT and rest-stress myocardial perfusion SPECT, respectively All of them underwent both myocardial perfusion SPECT and coronary angiography within 1 month. A coronary stenosis was considered significant when it compromised the luminal diameter by> or =50%. The chi square test was used to compare differences in sensitivity, specificity and accuracy between the two groups. The overall sensitivity, specificity and accuracy of stress-rest protocol were 99%, 35%and 68%, respectively. Those of rest-stress protocol were 96%, 47%, and 78%, respectively. There was no difference between the two protocols in identifying individual diseased coronary artery branches. Therefore, one day stress-rest and rest-stress myocardial SPECT using Tc-99m agents were comparable and were very sensitive tests in detecting coronary artery diseases.

Pseudocyst of the auricle presents as a non-inflammatory, fluctuant swelling on the upper half or third section of the ear, due to intracartilaginous accumulation of fluid. Histological examination shows an intracartilaginous cavity without an epithelial lining. The etilogy and pathogenesis of this disorder remains unknown, but the lesion is likely to be due to localized de-generation of cartilage. The degenerated cartilage is replaced by a vascular fibrous tissue from which there is serious exudation, and a clinical cystic swelling is formed. We describe in this report three cases of pseudocyst of the auricle, of which one was treated successfully by surgical excision and a pressure dressing, and the others by aspiration and steroid injection therapy. In all cases, the skin lesions had not recurred, and the patients were left with an excellent cosmetic result.
