A 33-year-old man was referred to our hospital with the complaints of a longlasting constipation and nonspecific lower abdominal pain. At ultrasound, a cystic mass was detected at the presacral space. Computed Tomography revealed a defect at the anterior aspect of the sacrum, together with a presacral cystic mass which showed a connection with the dural sac. At Magnetic Resonance Imaging, it was demonstrated that the cystic mass made an impression on the rectum, and did not possess any solid components. An anteroposterior pelvis radiogram demonstrated a sacral deformity and the scimitar sign. Upon these imaging findings, the patient got the diagnosis of an anterior sacral meningocele. The possibility of an anterior sacral meningocele must always be kept in mind in the differential diagnosis of a pelvic cystic mass.展开更多

In order to achieve the above-mentioned goal, the knees of individuals from two distinct groups were examined by MRI. One group consisted of osteoarthritis patients while the other comprised the control individuals. All individuals from both groups underwent clinical and MRI measurements concerning their knees. These data were compared by using the statistical software from the Statistical Package for Social Sciences (SPSS) v.15 program. Statistically significant differences were found between the control and patients groups in terms of the measurements of the second (short) diameter of the medial femoral condyle, and the intercondylar distance (p < 0.05). In addition to these findings, the Receiver Operating Characteristics (ROC) curve analysis gave statistically significant results for both of these measurements. The cutoff values for these criteria were as follows in sequence order: a sensitivity of 75% and a specificity of 52% for the medial femoral condyle, and a sensitivity of 70% and a specificity of 70% for the intercondylar distance. The ROC curve data may not be a deterministic outcome alone for this study. But it may in fact have a significant meaning when it is evaluated together with other statistically significant data. The t-test for Equality of Means, for example, gave significant results, concerning the measurements of the short axis of the medial femoral condyle and the intercondylar distance. It is well known that it is the medial portion of the knee joint which deteriorates the most during the process of osteoarthritis of the knee (OAK), and this complies with the results of this study.展开更多
