    The hepatic and renal veins drain into the inferior vena cava. The upper group of hepatic veins consists of three veins which extend to the posterior face of the liver to join the inferior cava. The left renal vein passes anterior to the aorta just below the origin of the superior mesenteric artery. We detected a variation in the hepatic and renal veins in a multislice CT angiogram of a nine-year-old male patient in the Radiology Department of Afyon Kocatepe University Medical School. The upper group hepatic veins normally drains into the inferior vena cava as three separate trunks, namely the right, left and middle. In our case, we found that only the right and left hepatic veins existed and the middle hepatic vein was absent. Furthermore, the left renal vein, which normally passes anterior to the abdominal aorta, was retro-aortic. Left renal vein variations are of great importance in planning retroperitoneal surgery and vascular interventions. Knowledge of a patient's hepatic vein and renovascular anatomy and determining their variations and anomalies are of critical importance to abdominal operations, transplantations and preoperative evaluation of endovascular interventions

    Background: The aim of this study is to assess and document the dimensions of the normal spleen measured on computed tomography (CT) images with the normal splenic volume measured by Cavalieri principle on CT images and thereby serve as a baseline for comparison in cases of splenomegaly using abdominal CT. To investigate the relationship between these changes and body mass index, gender, abdominal diameters. Materials and methods: We retrospectively reviewed abdominal CT examinations of 212 adults between the ages of 20 and 88 years. There were seven groups of patients. The spleen volume (SV) measurements using abdominal CT images of each patient on the Image Information Systems were performed with Cavalieri principle. Results: The mean SV and splenic length (SL), width (SW), and thickness (ST) for the total study population of 212 patients was 198 +/- 88 cm(3), 9.96 +/- 2.1 cm, 8.87 +/- +/- 1.6 cm and 4.58 +/- 0.8 cm, respectively. There was a strong correlation between SV and ST (r = 0.752, p < 0.001), SL (r = 0.735, p < 0.001), SW (r = 0.681, p < 0.001) mean values of total study population. Comparison between mean splenic dimension parameters for males and females showed a statistically significant difference (p = 0.032 for SV, p = 0.04 for ST) but no statistically significant difference with SL and SW. Also there was a positive correlation between SV and body height, sagittal abdominal diameter and transvers abdominal diameter in mean of total groups and female groups, there was no correlation in males. Conclusions: The normal reference ranges for SV and size given in this study can serve as a standard to judge whether splenomegaly is present in patients

    Objective: To evaluate the effects of temporal lobe epilepsy (TLE) on corpus callosum (CC) morphometry in patients with TLE. Methods: This retrospective study was conducted at the Faculty of Medicine, Tekirdag Namik Kemal University, Tekirdag, Turkey between November 2010 and December 2013. The epileptic syndrome diagnosis was based on International League Against Epilepsy criteria, and this study was conducted on the MRIs of 25 epilepsy patients and 25 control subjects. We classified the patients according to their duration of epilepsy: = 10 years. The projection area length (PAL) of the CC was also estimated. Total brain volumes (TBV) were measured on CT images. Results: The mean values of TBV for patients with TLE and the control group were not statistically different, but the CC PAL values were statistically different. The mean CC PAL values of under and over 25 years of age in patients with TLE were statistically different. The mean values of TBV of under and over 10 years duration of TLE were small statistically, but the CC PAL values were statistically different. Conclusion: The results indicate a clear influence of TLE on the structure of the CC rather than TBV

    Amaç: Çalışmamızda çocuklarda hemiplejik serebral palsi’nin HSP neden olduğu üst ekstremite gelişim geriliğinin antropometrik yöntemlerle incelenmesi amaçlandı. Gereç ve yöntem: Çalışmamızda Etik Kurul onayı alınarak 5-12 yaşlarındaki 32 HSP’li çocuk ile 40 normal çocuğun üst ekstremiteleri antropometrik set ile ölçülerek karşılaştırıldı. Bulgular: HSP’li çocukların sağlam taraf omuz eklemi, kol, dirsek eklemi, ön kol ve el bilek eklemi çevresi; üst ekstremite, kol, ön kol, el ve el ayası uzunluğu; dirsek eklemi, el bilek eklemi ve el genişliği değerleri HSP’li çocukların plejik tarafına göre anlamlı derecede fazlaydı. Normal çocukların omuz eklemi, kol, dirsek eklemi, ön kol ve el bilek eklemi çevresi; üst ekstremite, kol, ön kol, el ve el ayası uzunluğu; dirsek eklemi, el bilek eklemi ve el genişliği değerleri HSP’li çocukların plejik taraf ölçümlerine göre anlamlı derecede yüksekti. Normal çocukların dirsek eklemi ve ön kol çevresi; el ve el ayası uzunluğu; dirsek eklemi, el bilek eklemi ve el metakarpallerden genişliği değerleri HSP’li çocukların sağlam tarafına göre anlamlı derecede yüksekti. Sonuç: Antropometrik ölçümler HSP’li çocukların plejik taraf üst ekstremitelerinin sağlam tarafa göre, normal çocuklarla karşılaştırdığımızda ise hem plejik hem de sağlam taraflarının daha az geliştiğini göstermektedir. HSP’li çocukların az gelişmiş plejik taraflarını kullanamamaları günlük yaşam aktivitelerini de kısıtlayarak sağlam tarafta da kas ve kemik gelişim geriliğine sebep olmaktadır. Erken teşhis ve rehabilitasyon ile bu fark azaltılabili
