Lumbar opening pressure and radiologic scoring in idiopathic intracranial hypertension : is there any correlation?

Background: To investigate correlation between lumbar opening pressure (LOP) and radiological scores based on cranial MRI and contrast-enhanced MR venography in patients with idiopathic intracranial hypertension (IIH). Material/Methods: Patients with IIH who underwent brain MRI and contrast-enhanced MR venography before measurement of LOP between 2010-2014 were evaluated retrospectively. Three experienced radiologists (blinded to LOP values) evaluated a total of 51 patients. They reached a consensus on the presence or absence of 6 radiological findings identified in the literature as characteristic for IIH: empty sella, perioptic dilation, optical tortuosity, flattening of the posterior globe, swelling of the optic disc, and bilateral transverse sinus stenosis. The radiological score was obtained by giving 1 point for the presence of each finding, with the highest possible score of 6 points. The correlation between the calculated radiological scores and LOP was evaluated. Results: There was no significant correlation between LOP and radiological scores (r=0.095; p=0.525, Spearman's rank coefficient). Similarly, no significant correlation was detected between LOP and each of the radiological findings (partial empty sella [p=0.137], perioptic dilation [p=0.265], optical tortuosity [p=0.948], flattening of the posterior globe [p=0.491], swelling of the optic disc [p=0.881], and bilateral dural sinus stenosis [p=0.837], Mann-Whitney U test). Conclusions: There was no significant correlation between LOP and reliable radiological features of IIH

Assessment of hepatic artery flow volume changes due to hepatosteatosis on pediatric obese patients

Amaç: Pediatrik yas grubunda obesiteye baglı hepatosteatozun hepatik arterin akım volümü üzerine olan etkisinin, doppler ultrasonografi kullanılarak arastırılması amaçlandı. Gereç ve Yöntem: Yasları 8,5 ile 17 arasında degisen, normal vücut kitle indeksine sahip 32 ve obes vücut-kitle indeksine sahip 42 hastanın, hepatik arter akım volümü doppler ultrasonografi ile degerlendirildi. Bulgular: Obes hasta grubu ile normal grup arasında hepatik arter akım volümü ortalamaları arasında anlamlı fark saptanmadı (p>0.05). Hepatosteatoz derecesinin artısı ile hepatik arter akım volümünde artıs izlenmekle birlikte, istatistiksel anlamda farklılık bulunmadı (p>0.05). Obesite ile hepatosteatoz arasında güçlü korelasyon izlendi (r=0.638). Sonuç: Obesiteye baglı hepatosteatozun derecesindeki artıs ile hepatik arter akım volümünde göreceli artıs izlenmekte olup, bu parametrenin kullanımı rutin takip incelemelerde sınırlı da olsa katkı saglayabilir. Objective: The purpose of the study is to determine the effect of obesity related hepatosteatosis on hepatic artery flow volume by Doppler ultrasonography in pediatric patients. Materials and methods: The hepatic artery flow volume of 42 obese patients according to BMI and 32 patients having normal BMI were evaluated using Doppler ultrasonography. The ages of the patients were between 8.5 and 17. Results: There was no statistically significant difference between the normal group and obese group according to the mean hepatic artery flow volume (p>0.05). Increased hepatic artery flow volume was parallel with increased grade of hepatosteatosis, however, this was not statistically significant (p>0.05). Strong correlation was observed between obesity and hepaosteatosis. Conclusion: Increased grade of hepatosteatosis due to obesity is accompanied with a relative increase in hepatic artery flow volume. The use of this parameter can provide limited contribution in routine follow up examinations

MRI Findings in Biliary Cystadenoma

Biliary cystadenoma is a rare cystic hepatic neoplasm. We herein present a 44 year-old female patient with biliary cystadenoma focusing on difficulties in diagnosis because of lack of specific findings with imaging, and the need for surgery. As biliary cystadenomas have high recurrence risks and malignant transformation potential, careful follow-up should not be underestimated. Proper surgical resection of the lesion may be considered the most suitable diagnostic and therapeutic procedure, and prognosis is generally excellent after removal of the tumor

Endovascular stent-graft treatment of giant celiac artery pseudoaneurysm

BACKGROUND: Visceral artery aneurysms (VAAs) comprise an uncommon but life-threatening vascular disease. When rupture is the first clinical presentation, mortality rate reaches 70%. Increased use of cross-sectional imaging has led to a greater rate of diagnosis (40-80%) of asymptomatic VAAs. In the past, surgery was the treatment of choice for VAAs carrying high risk of mortality and morbidity. CASE REPORT: A 22-year-old man, who had undergone gastric, pancreatic and aortic surgery 2.5 years earlier, presented with progressive abdominal pain. Multidetector computed tomography scan revealed an 8-cm celiac pseudoaneurysm. We report a giant celiac pseudoaneurysm treated with stent-graft implantation. CONCLUSIONS: Endovascular treatment of VAA is a safe and effective method alternative to surgery
