ABSTRACT
The corpus callosum [CC] is an important structure of connecting the two cerebral hemispheres. The purpose of this study was to examine the morphometry of the CC of normal cases and its relationship with gender and age. Morphometric measurements of the corpus callosum were made on MR imaging in the mid-sagittal plane in 42 male and 48 female total 90 healthy subjects, age range was 6-17 year-old. Age of the cases were divided into three group as 6-9, 10-13 and 14-17 year-old. The length was measured by drawing a straight line at greatest antero-posterior diameter of CC, a perpendicular at its midline, anterior, posterior and medium segments of CC were measured. In addition as a result of these morphometric measurements index of corpus callosum [CCI] was calculated for every cases. Statistical analysis was performed by One-Way ANOVA- Tukey test, Independent Sample t test, Kruskal-Wallis test and Mann - Whitney U test. Without considering sex between the age group, antero-posterior, anterior, posterior and medium segments diamaters of CC was found statistically significance [p < 0.05] while analysis of CCI values was not found significant [p > 0.05]. These datas can be used as morphometric guide, for evaluation of the CC specially in years 6-17 age group
ABSTRACT
OBJECTIVE: We wanted to compare the efficacies of 95% ethanol and 20% hypertonic saline (HS) sclerotherapies that were performed in a single session under CT guidance for the management of simple renal cysts. MATERIALS AND METHODS: A prospective series of 74 consecutive patients (average age: 57.6 +/- 8.1 years) with simple renal cysts were enrolled in this study. They were randomized into two groups and 95% ethanol or 20% HS, respectively, corresponding to 25% of the aspiration volume, was injected. Treatment success was determined six months later with follow-up clinical evaluation and performing ultrasonography. RESULTS: The sclerotherapy was accepted as technically successful without major complications in all except two patients who were excluded because of a communication between the simple renal cyst and the pelvicalyceal collecting system. Thirty-six patients in the ethanol group received sclerotherapy with 95% ethanol and 36 patients in the HS group underwent sclerotherapy with 20% HS. The complete regression ratio of the ethanol group was significantly higher (94% versus 72%, respectively) than that of the HS group. There was one patient with partial regression in each group. The failure ratio of the ethanol group was significantly lower (3% versus 25%, respectively) than that of the HS group. CONCLUSION: Ethanol sclerotherapy under CT guidance is a successful and safe procedure and it can be used for the treatment of simple renal cysts. Sclerotherapy with 95% ethanol is more effective than 20% HS sclerotherapy. Sclerotherapy with HS may be an option for patients preferring to undergo a less painful treatment procedure.
