PURPOSE: The medial meniscus is injured much more than the lateral meniscus. Because the medial meniscus is much larger in diameter, is thinner in its periphery and narrower in body than the lateral meniscus, and does not attach to either cruciate ligament. We evaluated correlations with sites of tear and history of trauma. METHODS AND MATERIALS: We reviewed retrospectively in 43 patients with meniscal tears on MRI(51 cases) and correlated them with history of trauma. RESULTS: The most common site of injury was the posterior horn of the medial meniscus(32/51), but high incidence of lateral meniscal tear compared with previous reports was seen. In the cases which had history of trauma, the posterior horn of medial meniscus was most commonly injured(26/34) and 5 meniscal tears were combined with meniscal tear in the other site. The tear in the anterior horn of the medial meniscus was seen only in a patient which had history of trauma and combined with meniscal tear in the other site. But in the meniscal tears without definite history of trauma, the incidence of meniscal tear was different from the meniscal tear with history of trauma. The incidence of lateral meniscal tear(11/17) was highter than medial meniscal tear and the posterior horn of lateral meniscus was commonly injured. CONCLUSION: We concluded that the medial meniscus was commonly injured, especially posterior horn, but in the cases which had no definite history of trauma, the lateral meniscus was commonly ipjured. An awareness of prevalent site of meniscal injuries may be helpful in the diagnostic interpretation of MR imaging of knee.

Amyloid goiter is a rare disease entity that is defined as a symptomatic mass or clinically detectable thyroid enlargement because of amyloid deposition. We present a case of amyloid goiter diagnosed in the fine needle aspiration cytology(FNAC) in a 73-year-old Korean woman presented with nephrotic syndrome and thyroid enlargement. The thyroid function was in normal range. Thyroid scan showed a nodule, 4x2 cm in the right lobe with underlying diffuse goiter. Aspirates revealed benign looking follicular cells and scattered eosinophilic material. The sections of the cell block showed nodular deposit of eosinophilic hyalinized material in the interfollicular area. It showed apple-green birefringence under polarization with Congo red stain. The renal biopsy also exhibited deposition of eosinophilic materials in the glomeruli and interstitial vascular wall, which were confirmed as amyloidosis. This material was morphologically distinct from the colloid.

PURPOSE: To determine the sonographic findings of degenerative change in femoral articular cartilage of the knee by comparative study of specimen sonography and pathology. MATERIALS AND METHODS: We obtained 40 specimens of cartilage of the femur (20 medial and 20 lateral condylar) from 20 patients with osteoarthritis of the knee who had undergone total knee replacement. The specimens were placed in a saline-filled container and sonography was performed using a 10MHz linear transducer. Sonographic abnormalities were evaluated at the cartilage surface, within the cartilage, and at the bone-cartilage interface, and were compared with the corresponding pathologic findings. In addition, cartilage thickness was measured at a representative portion of each femoral cartilage specimen and was compared with the thickness determined by sonography. RESULTS: 'Dot 'lesions, irregularity or loss of the hyperechoic line, were demonstrated by sonography at the saline-cartilage interface of 14 cartilages. Pathologic examination showed that these findings corresponded to cleft, detachment, erosion, and degeneration. Irregularities in the hyperechoic line at the bone-cartilage interface were revealed by sonography in eight cartilages and were related to irregularity or loss of tidemark, downward displacement of the cartilage, and subchondral callus formation. Dot lesions, corresponding to cleft and degeneration, were noted within one cartilage. Cartilage thickness measured on specimen and by sonography showed no significant difference (p=0.446). CONCLUSION: Specimen sonography suggested that articular cartilage underwent degenerative histopathological change. Cartilage thickness measured by sonography exactly reflected real thickness.

Background : Fascin, an actin-bundling protein, has been found in specialized normal cells, including the neuronal, endothelial and dendritic cells, and its expression is known to be greatly increased in various human neoplasms. Methods : Immunohistochemical stainings for fascin, betacatenin, and E-cadherin were performed in normal ovary tissue (n=13), and in benign (n=14), borderline (n=32), and malignant (n=74) ovarian serous neoplasms. We evaluated the fascin expression, and its relationship with the betacatenin and E-cadherin expressions, as well as the clinicopathologic factors. Results : Fascin expression was detected in the majority of the borderline (100%, 32/32) and malignant tumors (90.5%, 67/74), but it was not seen in the normal ovarian surface epithelial cells and the benign tumors (p<0.001). Fascin expression was significantly correlated with the occurrence of peritoneal metastases in the carcinomas (p=0.043). A significant relationship between the expressions of fascin and betacatenin (p=0.046), as well as E-cadherin (p=0.035) was noted. There was no significant correlation with the tumor grade of carcinoma, the FIGO stage, tumor recurrence, tumor-related death and the survival rate. Conclusions : In ovarian serous neoplasms, the fascin expression may be closely linked with tumor progression and metastasis, and it was associated with the up-regulation of betacatenin and E-cadherin.
