N/A Gastric leiomyoma is the most frequent type of non-cancerous gastric neoplasm. The prognosis for gastric leiomyoma is better than adenocarcinoma, leiomyosarcoma and the others, so correct diagnosis is essential for proper management. Authors analysed 8 cases of gastric leiomyoma, diagnosed by operation in 6 cases and endoscopic biopsy in 2 cases, at Kyung Hee University Hospital from December 1984 to October 1988. The results were as follows; 1) The size of gastric leiomyoma ranged from 3 to 10 cm with the mean diameter of 5 cm. 2) The tumor was located at fundus in 2 cases, body in 2 cases and antrum in 4 cases. 3) The echogenicity of mass compared with liver parenchyme was hypoechoic in 5 cases (63%), isoechoic in 2 cases (25%) and heterogeneous in one case (12%). 4) The growth patten of tumor was endogastric in 5 cases (63%) and exophytic in 3 cases (37%). 5) Ulceration was found in 5 cases (63%) at central part of tumor. 6) Ultrasonographic diagnosis of gastric leiomyoma was made in the presence of following contions. ① A small hypoechoic mass with smooth margin. ② Endogastric growth continuous to submucosa. ③ Intact mucosa surrounding mass.④ Small ulceration without tumor necrosis.

We reviewed the Magnetic Resonance Imagings(MRI) of 41 knees in 41 patients who had confirmed discoid lateral menisci of the knee joint arthroscopically from Nov. 1991 to Jan. 1994. The purpose of this study is to demonstrate the diagnostic value of MR imagings for discoid lateral meniscus and to describe the characteristic findings of MR imagings according the type of tears and to explain the causes of mis-diagnosis. Type of tears were confirmed by either arthroscopic finding or gross specimen. Peripheral detachment were found in 13 discoid menisci(31.8 %), complex tears in 16(39.0 %), horizontal tears in 5(l2.2%), longitudinal tears in 4(9.8%), transverse tears in 2(4.8 %) and intact in 1(2.4 %) discoid meniscus. 36 out of 41 discoid lateral menisci(87.7%) were correctly diagnosed as discoid menisci preoperatively on MR imaging. However 5 were mis-diagnosed as lateral meniscal tear. It was very difficult to diagnose discoid lateral meniscus which had detached from meniscosynovial junction and displaced into the center or had transverse tear in mid-horn. We also found that MR imagings showed the correct torn shape of 27 out of 36(75 %) discoid lateral nenisci which were correetly diagnosed as discoid menisci. Accuracy of MR imagings for each type of tear were follwings : 50 % for horizon, 100 % for peripheral tear, 73.3 % for complex tear 33.3 % for longitudinal tear, 0% for tranverse tear. On the MR imaging, capsular attachments of the popliteal muscle in knees with discoid meniscl were compared to those of 100 knees with normal lateral menisci. Capaular attachments of popliteal muscles were divided to three : type 1 is fibrous band, type 2 is thin muscle bundle, type 3 is thick muscle bundle. Capsular attaehments of popliteus muscle in the knees with discoid meniaci(68.3 %) had significantly higher incidienee of type 2 or 3 compare to the knees with normal lateral meniacus(32 %). As conclusion, MR imagings for diagnosing of discoid lateral meniscus had a relatively accurete diagnotic value and also shoed the its type of tear. It is very important to realize type of dicoid meniscal tear in order to obtain correct diagnosis.
