A case of 26 years old male having horseshoe kidney associated with giant hydronephrosis due to aberrant vessel was presented with a brief review of the literatures. The patient was managed by division of isthmus and nephrectomy with good result.

PURPOSE: To evaluate the optimal pulse sequences in the detection of erosions and for the discrimination of theeffusion from pannus. MATERIALS AND METHODS: MR studies were performed in thirteen patients with clinical diagnosis of rheumatoid arthritis. We used a 1.5T MR unit with single or dual 3 inch coil. We compared coronal images at the same location, obtained with pulse sequences of T2, T2 with fat saturation, and postcontrast T1 with fat suppression. Erosions were assessed by comparing the count of the numbers of erosions depending on each imaging method. A four point scoring systems was used for the comparison of conspicuitof lesion. RESULTS: T2WI with fat suppression and postcontreat T1WI with fat suppresison were better than conventional T2WI in the detection of erosions. The pannus had a heterogeneous signal on T2WI, some of which were enhanced after the intravenous injection of MR contrast a gents. CONCLUSION: We suggest that the fat suppression TIWI with enhacnement or the fat suppression T2WI were better than conventional T2WI for detecting both bone erosion and pannus. The postcontrast MR imaging may often be helpul in distinguishing pannus from the effusion.

We report a case of pulmonary infarction probably related with Henoch-Schönlein purpura, which presented with purpura on both lower extremities in a 27-year-old woman. The purpura had developed 4 days previously and it had no itching or tend'erness. She complained of mild fatigue, chest tightness, but no dyspnea or hemoptysis. On routine examination, chest radiography showed a poorly defined nodular opacity on the left lung field, and it was diagnosed by a follow up chest CT as a pulmonary infarction secondary to pulmonary vasculitis.

PURPOSE: For the production and evaluation of the tissue-equivalent phantom. MATERIALS AND METHODS: We used agarous gel and oil as a basic component of the mixture and added Tween 80 for the stabilization of phantoms. We did the test for homogeneity and measured T1 and T2 relexation times of each phantom tube. RESULTS: T1 relaxation time ranged from 642 to 2781 msec and T2 relaxation times from 42 to 157 msec. Each phantom was significantly different in T1 relaxation time and T2 relaxation time (p < .0001). CONCLUSION: Tissue equivalent phantom may provide good information on the optimal sequence before MR imaging of patients and may be valuable if it is used with the patients' MR imaging.

Diagnosis*

Osteosarcoma is one of the most common malignant bone tumors except for multiple myeloma. The current managements of the osteosarcoma patients include preoperative chemotherapy, definitive operation and postoperative chemotherapy with tremendous improved oncologic results by lots of Orthopedic Oncologists. The definitive operations are either limb-salvage operations or amputation. Limb-salvage operations include autograft, allograft, tumor prosthesis, or its combination. However, we have a difficulty to use allograft due to Korean traditonal customs. Authors managed the 6 year-old female patient with the osteosarcoma on the proximal metaphysis of the right humerus by wide-margin resection and reconstruction with a clavicula pro humero procedure with an excellent result, which technique was devised and developed by W. Winkelmann in Germany.

The clinical observation was made on 174 patients with congestive heart failure among the admitted patients in Chung Ang university hospital between 1971 and July, 1978. The results were summarized as follows: 1. There were 89 females and 85 males and the incidence was the highest in the 6th decade. 2. The common causes of congestive heart failure were hypertensive heart disease 44.8%, valvular heart disease 21.3% and ischemic heart disease 9.2%. 3. The precipitating factors of congesive heart failure were found in 73.6% of cases and the major factors were arrhythmia 25.3% and infection 15.5%. 4. The important symptoms and signs were dyspnea 86.8%, hepatomegaly 53.4%, pulmonary rales 49.4%, cardiac murmur 46%, tachycardia 35.1% cough 35.1% and orthopnea 34.5%. 5. The ECG findings were abnormal in 92.1% of cases and the frequent abnormal findings were inverted or flat T wave 47.3%, atrial fibrillation 40.6% and left ventricular hypertrophy 33.3%. 6. The chest PA on admission revealed abnormalities in 159 cases, including cardiomegaly 74.6%, pulmonary congestion 66.9% and pleural effusion 26.6%. 7. The major abnormalities of laboratory data were proteinuria and the increase of globuline, BUN, TTT, alkaline phosphatase and SGOT.
