Abstract
INTRODUCTION We aimed to evaluate 304 premenopausal women admitted to our clinic for oligomenorrhoea, and to screen for Cushing's syndrome (CS) in this population. MATERIAL AND METHODS The study included 304 premenopausal women referred to our clinic for oligomenorrhoea. Anthropometric measurements and Ferriman-Gallwey score were evaluated, and thyroid hormone, follicle-stimulating hormone (FSH), luteinizing hormone (LH), total testosterone, prolactin, dehydroepiandrosterone sulphate (DHEA-S), and 17-hydroxyprogesterone (17-OHP) levels were measured in all patients. If basal 17-OHP was > 2 ng/mL, we evaluated adrenocorticotropic hormone (ACTH)-stimulated 17-OHP levels. CS was screened by 1 mg-dexamethasone suppression test, and if the cortisol value was > 1.8 μg/dL, we performed additional confirmatory tests, and if necessary, pituitary magnetic resonance imaging (MRI) and inferior petrosal sinus sampling (IPSS) were performed. RESULTS The most common cause of oligomenorrhoea was polycystic ovary syndrome (PCOS) that was detected in 81.57% of cases, followed by hyperprolactinemia at 7.23% and hypothalamic anovulation at 5.26%. The prevalence of premature ovarian failure (POF) was 1.6%, and non-classical congenital adrenal hyperplasia (NCAH) was 1.97%. CS was detected in 7 (2.30%) patients. All the patients with CS were found to have Cushing's disease (CD). Although 3 patients with CD had classical signs and symptoms, 4 had none. Patients with CD had similar total testosterone values to those in the PCOS and NCAH groups, but they had significantly higher DHEA-S compared to both groups (CD vs. PCOS, p = 0.001 and CD vs. NCAH, p = 0.030). CONCLUSIONS We found higher prevalence of CS in patients with oligomenorrhoea even in the absence of clinical signs. Therefore, we suggest routine screening for CS during the evaluation of patients with oligomenorrhoea and/or PCOS. The likelihood of CS is greater in patients with high androgen, especially DHEA-S levels.

Abstract
PURPOSE Our aim was to evaluate the performance of clot-based radiomics features (RFs) for predicting first pass effect (FPE) in patients with acute ischemic stroke (AIS). The secondary purpose was to search for any other variables associated with FPE. MATERIALS AND METHODS Patients who underwent mechanical thrombectomy (MT) for anterior circulation large vessel stroke in a single center were retrospectively reviewed. Patients were divided into two groups: FPE and non-FPE. Two observers extracted RFs from the clot on pretreatment noncontrast computed tomography (NCCT) images. Demographic, clinical, periprocedural, and RFs were compared between the groups and receiver operating characteristic (ROC) curves were constructed. Logistic regression analysis was used to determine the independent predictors of FPE. RESULTS Fifty-two patients (27 female, 25 male; mean age 64.50 ± 15.15) who were treated by stent retrievers as the first option were included in the study. FPE was achieved in 25 patients (25/52, 48.1%). Twelve RFs were significantly different between patients with FPE and non-FPE. The long-run low gray-level emphasis (odds ratio = 44.24, p = 0.003) and the zone percentage (odds ratio = 16.88, p = 0.017) were found as independent predictors of FPE. Female sex and a baseline ASPECT score of >8.5 were the other independent variables to predict FPE. The diagnostic accuracy to predict FPE was observed as 83% when using all independent predictors in our predictive model. CONCLUSIONS Clot-based RFs on NCCT may help to estimate the success of the intended outcome of MT in patients with AIS.

Abstract
OBJECTIVES To evaluate the performance of CT-based texture analysis (TA) for predicting clinical outcomes of mechanical thrombectomy (MT) in acute ischemic stroke (AIS). METHODS This single-center, retrospective study contained 64 consecutive patients with AIS who underwent MT for large anterior circulation occlusion between December 2016 and January 2020. Patients were divided into 2 groups according to the modified Rankin scale (mRS) scores at 3 months as good outcome (mRS ≤ 2) and bad outcome (mRS > 2). Two observers examined the early ischemic changes for TA on baseline non-contrast CT images independently. Demographic, clinical, periprocedural, and texture variables were compared between the groups and ROC curves were made. Logistic regression analysis was used and a model was created to determine the independent predictors of a bad outcome. RESULTS Sixty-four patients (32 female, 32 male; mean age 63.03 ± 14.42) were included in the study. Fourteen texture parameters were significantly different between patients with good and bad outcomes. The long-run high gray-level emphasis (LRHGE), which is a gray-level run-length matrix (GLRLM) feature, showed the highest sensitivity (80%) and specificity (70%) rates to predict disability. The GLRLM_LRHGE value of > 4885.0 and the time from onset to puncture of > 237.5 mi were found as independent predictors of the bad outcome. The diagnostic rate was 80.0% when using the combination of the GLRLM_LRHGE and the time from onset to puncture cutoff values. CONCLUSION CT-based TA might be a promising modality to predict clinical outcome after MT in patients with AIS. KEY POINTS • The gray-level run-length matrix parameters displayed higher diagnostic performance among the texture features. • The long-run high gray-level emphasis showed the highest sensitivity and specificity rates for predicting a bad outcome in stroke patients undergoing mechanical thrombectomy. • The gray-level run-length matrix_long-run high gray-level emphasis value of > 4885.0 (OR = 11.06; 95% CI = 2.51 - 48.77; p = 0.001) and the time from onset to puncture of > 237.5 min (OR = 8.55; 95% CI = 1.96 - 37.21; p = 0.004) were found as independent predictors of the bad outcome.

Abstract
PURPOSE Our aim was to determine the long-term safety and efficacy of the Flow Re-Direction Endoluminal Device (FRED) in this multicenter study with prospective design. MATERIALS-METHOD This study included 136 consecutive patients with 155 aneurysms treated between March 2013 and June 2016 in 10 centers. Twenty-two (16.2%) patients presented with rupture of the index aneurysm. Large/giant aneurysms comprised 1/3 of the cohort. Adjuvant coil use during the treatment was 15.5%. The effectiveness measure in the study was the percentage of aneurysms with stable occlusion at follow-up. RESULTS Vascular imaging follow-up was performed at least once in 131/136 (96.3%) patients with 148/155 (95.5%) aneurysms up to 75 months (mean: 37.3 months; median: 36 months according to latest follow-up), and 102/155(65.8%) aneurysms in 90/136 (66.2%) patients had ≥ 24-month control. According to the latest controls, the overall stable occlusion rate was 91.9% (95% CI, 87.5 to 96.3%). Three out of 148 aneurysms with follow-up were retreated (2%, 95% CI 0.0 to 4.3%). Adverse events were noted in 19/136 (14%, 95% CI, 9 to 21%) patients with a morbidity of 1.5% (95% CI, 0.0 to 3.5%). Mortality was 1/136 (0.7%, 95% CI, 0.02 to 2.2%) and was unrelated to aneurysm treatment. In-stent stenosis (ISS) was detected in 10/131 of the patients with follow-up (7.6%, 95% CI; 3.1 to 12.2%), only one being symptomatic. No adverse events have occurred in any of the patients with follow-up after 24 months, except the one resulting from ISS. CONCLUSION In the treatment of cerebral aneurysms which were candidates for flow diversion technique, this study showed long-term efficacy of FRED with good safety and occlusion rates.

Abstract
PURPOSE The aim of this study was to evaluate the relationship between platelet-lymphocyte ratio (PLR) and first pass effect (FPE) in patients with acute ischemic stroke (AIS). Our secondary goal was to investigate other laboratory, demographic or technical parameters that may be related to FPE and to search for independent predictors of FPE. MATERIALS AND METHODS Patients who underwent mechanical thrombectomy (MT) in our hospital between January 2017 and February 2020 were reviewed. Patients were divided into two groups: FPE and non-FPE. Demographic features, laboratory parameters, pretreatment imaging and clinical features, angiographic and clinical outcomes were recorded and compared between the two groups. Logistic regression analysis was performed to analyze the independent predictors and a predictive model was produced for demonstrating the possibility to achieve FPE. RESULTS The study consisted of 83 patients (37 female, 46 male; mean age 62.69 ± 15.16) who were treated by MT. FPE was achieved in 32 patients (32/83, 38.6%). PLR was higher in the non-FPE group (195.35 ± 101.49) when compared to the FPE group (103.17 ± 37.06). A PLR value of <126.3 and female sex were found as independent predictors of FPE. Our predictive model estimated the chance of FPE as 77.9% in female patients who had PLR values lower than 126.3 while it was 77.1% when only using the PLR cutoff value. CONCLUSIONS High levels of PLR were associated with the failure of FPE. High values of PLR may be considered as a negative predictor for FPE achievement prior to MT in patients with AIS.

Abstract
Objective We aimed to evaluate the angiographic findings and outcomes of bronchial artery embolization in tuberculosis patients and to compare them with those of non-tuberculosis patients. Materials and Methods Patients who underwent bronchial artery embolization in a single interventional radiology department with hemoptysis were reviewed. A total of 89 patients (66 males and 23 females; mean age 52.71±15.37) were incorporated in the study. The patients were divided into two groups: tuberculosis group (n=36) and non-tuberculosis group (16 malignancy, 22 bronchiectasis, 6 pulmonary infection, 5 chronic obstructive pulmonary disease, 4 idiopathic; n=53). Angiography and embolization procedure were performed by interventional radiologists with 5, 10, and 20 years of experience. Angiographic findings were classified as tortuosity, hypertrophy, hypervascularity, aneurysm, bronchopulmonary shunt, extravasation, and normal bronchial artery. Chi-square test was used to compare angiographic findings between tuberculosis and non-tuberculosis patient groups. Results Bronchopulmonary shunt was found to be significantly higher in the tuberculosis group as compared to that in the non-tuberculosis group (p=0.002). Neither of the groups showed a statistically significant difference with respect to recurrence (p=0.436). Conclusion Bronchial artery embolization is a useful and effective treatment method of hemoptysis in tuberculosis. Evaluation of bronchopulmonary shunts in patients with tuberculosis is critical for the reduction of catastrophic complications.

Abstract
BACKGROUND The platelet-lymphocyte ratio, which was reported to have a strong relationship with chronic inflammation and thrombosis, is a useful biomarker. The purpose of this study was to evaluate the relationship between the platelet-lymphocyte ratio, arteriovenous stenosis, and thrombosis in patients with chronic renal failure. METHODS Patients who were referred to our interventional radiology department due to arteriovenous fistula dysfunction from dialysis units between August 2015 and December 2018 were retrospectively reviewed. In the study, 95 patients with arteriovenous fistula access problems were included. Patients were divided into two groups: stenosis (n = 52) and thrombosis (n = 43). Thirty-six subjects with a patent left radiocephalic arteriovenous fistula proven by both color Doppler ultrasonography and clinically were added to the control group. Blood samples were obtained on the same day before the fistulography. RESULTS Platelet counts, lymphocyte counts, and platelet-lymphocyte ratio were found to be significantly different between the three groups. After the Bonferroni post hoc analysis, there was a significant difference between the stenosis and control group (p = 0.017), and the thrombosis and control group (p < 0.001) in terms of the platelet-lymphocyte ratio. No significant difference for any parameter was found between stenosis and thrombosis group. CONCLUSION High levels of the platelet-lymphocyte ratio may be a supportive finding of arteriovenous fistula stenosis and thrombosis and can be taken into consideration during hemodialysis-dependent patients' follow-up.

Abstract
Although a number of cases of retained surgical sponge (RSS) after thoracic and abdominal surgery have been reported in the literature, the occurrence of RSS after thyroidectomy is very rare. We report the imaging findings of three cases of RSS after thyroidectomy. Sonography of the three patients revealed a hyperechoic mass with marked acoustic shadow. Computed tomography showed a well-defined, circumscribed heterogeneous mass that had gas bubbles inside in two patients, whereas the mass in the third patient was hyperdense and homogenous with smooth margins. All three RSSs were surgically removed.

Abstract
Parkinson's disease (PD) is associated with degeneration of the dopaminergic neurons in the substantia nigra. The subthalamic nucleus (STN) plays a pivotal role in the pathogenesis. However, there is not much known about the morphological changes in the STN. The red nucleus (RN) has many connections with the motor coordinating pathways although it is not primarily involved in the pathogenesis. In this study we aimed to compare the volumes of the STN and RN measured by magnetic resonance imaging in PD patients and controls to investigate how these structures are affected at the morphological level. Twenty patients with PD and twenty age/sex matched controls were enrolled in this study. Severity score was determined by Hoehn & Yahr staging: 6 at stage II and 14 at stage III in med-off state. Imaging was performed by a 1.5 Tesla (T) MR scanner. Measurements of total brain and normalized STN and RN volumes were performed by manual planimetry using Image J software. No statistically significant differences were observed between two groups based on age or gender and disease stage and nuclei volumes. The total estimated brain volumes were not different between PD patients and controls. However, normalized volumes of the STN and RN were 14% and 16% larger, respectively, in PD patients compared to the controls (p < 0.05). Our findings suggest that the volumes of the STN and RN are increased in patients with PD. These changes possibly reflect the altered metabolic activity of these regions demonstrated by neurophysiological studies.

Abstract
OBJECTIVE To investigate diagnostic significance of percutaneous cavitary lavage (PCL) in differential diagnosis of benign and malignant pulmonary cavitary lesions. METHODS An alternative diagnostic method called PCL was performed on 16 patients having peripherally located pulmonary cavitary lesions with thin walls which were not suitable for tissue biopsy and whose diagnosis could not be made by sputum examination and bronchoscopic procedures. A 22-gauge needle was inserted into the cavity under computed tomography (CT) guidance. Saline was injected through the needle and then aspirated. The specimen was examined cytologically and microbiologically. RESULTS PCL could make a correct diagnosis in 12 of 16 patients (75%). In three patients (18.7%) appropriate specimen could not be taken. Diagnostic sensitivity and specificity of PCL for malignant-benign differentiation was 80% and 100%, respectively. The accuracy of PCL for this differentiation was 92.3%. There was only one complication, a small pneumothorax resolved without any intervention. CONCLUSIONS PCL is an alternative method in the differential diagnosis of thin walled pulmonary cavitary lesions especially for patients whose diagnosis could not be made by sputum and bronchoscopic procedures and who are not suitable for cutting needle biopsy.

Abstract
Anterior sacral meningocele (ASM) is a rare congenital anomaly, characterized by herniation through a defect in the anterior aspect of the sacrum. We reported a case of ASM associated with neurofibromatosis, which was mimicking a complex ovarian cyst in ultrasonography. ASM can easily be misdiagnosed as an ovarian cyst and needle aspiration can cause intracranial hypotension syndrome or even death.

Abstract
Pulmonary sequestration is an embryonic, cystic lung tissue that is supplied by systemic blood circulation. It is a nonfunctional lung parenchyma unconnected to normal tracheobronchial system. In cases of pulmonary sequestration, surgical interventions should be performed in order to prevent possible complications such as massive hemoptysis and infections. Preoperative imaging and treatment planning should be done carefully. We present an uncommon case of recurrent hemoptysis caused by intralobar pulmonary sequestration located in the left lower lobe.

Abstract
Rhinoliths are rare foreign bodies of the nose formed by in situ mineralization of endogenous or exogenous foreign material. They are often asymptomatic but may have various clinical presentations, with purulent rhinorrhea and nasal obstruction being the most common. They may go unnoticed for a long period and be diagnosed accidentally during a routine examination. We report a 6.5-year-old girl with rhinolithiasis complicated with sinusitis, frontal osteomyelitis and epidural abscess; she had a history dating back four years.

Abstract
BACKGROUND There are contradictory reports about the prevalence of cholelithiasis in chronic kidney disease (CKD). The pathogenesis of gallstones is associated with the lithogenic changes of bile composition, increased tendency to nucleation, and decreased gallbladder motility. The studies related to these factors can predict the development of cholelithiasis. The aim of this study was to evaluate the ultrasonic gallbladder function in CKD and to compare it in predialysis (PreD), hemodialysis (HD), and continuous ambulatory peritoneal dialysis (CAPD) patients. METHODS Age, gender, and body mass index matched 49 CKD patients (14 PreD, 19 HD, 16 CAPD), and 17 control individuals were included in the study. Diabetic and cirrhotic patients were not included. Ultrasonic gallbladder volume was evaluated in pre- and postprandial period, and ejection fraction was calculated. We also measured several biochemical parameters (cholesterol, triglyceride, blood urea nitrogen (BUN), creatinine, calcium, Phosphorus, parathormone, albumin, total protein) in blood. RESULTS Preprandial gallbladder volume in PreD, HD, CAPD, and control groups were 26.7 +/-13.6, 20.8+/-10.4, 23.2+/-14.7, and 26.4+/-14.8 mL, respectively (p > 0.05). Ejection fractions were 54.1 +/- 22.9%, 54.9 +/- 23.9%, 48.6 +/- 15.9%, and 51.8 +/- 19.2% in PreD, HD, CAPD, and control groups, respectively (p > 0.05). Serum triglyceride was higher in PreD patients than control group (207 +/- 144 vs. 110 +/-48 mg/dL) (p<0.05). Serum BUN, Cre, P, and PTH levels were higher in CKD groups than the control group, whereas serum total protein and albumin levels were higher in the control group (p<0.05). Serum Ca was lower in PreD and HD patients than in the controls (p<0.05). CONCLUSIONS In conclusion, CKD and renal replacement therapy (HD and CAPD) do not affect gallbladder functions, but more studies are needed to evaluate prevalence of gallstones, gallbladder motility, and the composition of bile in CKD.

Abstract
PRINCIPLES Coumadin-induced renal and retroperitoneal hemorrhages are rare. Clinical and laboratory findings are not specific for the diagnosis. Computed tomography (CT) has some advantages in the evaluation of these patients. The aim of this study is to report our experience regarding renal and retroperitoneal hemorrhage due to Coumadin, and describe clinical and CT findings, treatment, and prognosis of the patients. METHODS We reviewed our CT archive to search patients with renal and retroperitoneal hemorrhage caused by Coumadin treatment retrospectively. A total of seven patients with Coumadin-induced renal and retroperitoneal hemorrhages were included in this study. RESULTS Four patients had abdominal pain, two patients had hematuria, and one patient had abdominal pain and hematuria. There was retroperitoneal hemorrhage in three patients on abdominal CT. One patient had hemorrhage in the renal pelvis and the jejunum, another had hemorrhage in the renal pelvis and the perirenal area, and another had hemorrhage in the perirenal area and the retroperitoneal region. In the last patient with hematuria, there was no hemorrhage. None of the patients had a lesion-causing hemorrhage. Coumadin was stopped, and vitamin K and fresh-frozen plasma were given to patient. One patient with massive retroperitoneal hemorrhage died, whereas other patients were successfully treated using conservative approaches. CONCLUSIONS Hematuria and abdominal pain are the most common complaints in Coumadin-induced renal and retroperitoneal hemorrhage. CT can be the first imaging modality in these patients due to its ability to directly evaluate all peritoneal and retroperitoneal structures. It also allows evaluation of any underlying lesion that can cause hemorrhage from the renal area and the urinary tract. Conservative treatment is the first choice, and prognosis is good when diagnosed early.

Abstract
BACKGROUND Percutaneous drainage with alcohol injection for hydatid cysts has been commonly used in the last two decades. Albendazole is the drug of choice in the medical treatment of hydatidosis, and has also been used as an intraoperative scolicidal solution. The side-effects of its local application are not well known and have not been investigated. The purpose of the present study was to investigate the effects of the intracystic injections of alcohol and albendazole solutions on the hydatid cysts and hepatobiliary system of rabbits. METHODS There were three groups of eight rabbits: a control group, an alcohol group and an albendazole group. In all groups hepatic hydatidosis was obtained. The control group received no therapeutic procedure. Cyst liquid was aspirated, and alcohol or albendazole solutions were injected in the other two study groups. alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) levels, echinococcus indirect hemagglutination (IHA) tests, and the size and volume of the residual cysts were investigated. Liver was histopathologically evaluated. RESULTS The ALT, AST, GGT, and alkaline phosphatase (ALP) levels were significantly higher in the alcohol group, whereas echinococcus IHA level was highest in the control group than in the study groups. Albendazole had similar effects but of a lesser degree (P < 0.01). After therapy, the cyst volume was greater in the control than in the albendazole group (P < 0.01). In histopathological evaluation hepatocellular necrosis, portal inflammation and fibrosis were most severe in the alcohol group (P < 0.01). CONCLUSIONS Alcohol and albendazole solutions are effective as scolicidal solutions. Higher scolicidal effect and lesser side-effects on hepatobiliary system are the advantages of albendazole solution.

Abstract
Bladder exstrophy patients with or without augmentation have not been investigated according to metabolic bone problems, bone ages and growth, and development in details yet. We studied alterations in growth, bone ages, biochemistry of bone, bone mineral densities (BMD) of the forearm, neck of femur and lumbar vertebrae, blood gases, glomerular filtration rates (GFR), and electrolytes of 15 bladder exstrophy patients with augmentation and in those who had no augmentation. In six patients, a sigmoid colon was used for bladder augmentation and one patient underwent a ureterosigmoidostomy. Growth charts of all children were analyzed for determination of the percentiles. The parameters were compared with normal children and a comparison between augmented and nonaugmented patients were made. Growth retardation and decreased bone age were detected in all of the children. Ten patients with bladder exstrophy were below the 10th percentile for height. The mean age/bone age ratio of the patients was 1.59. The mean lumbar and femoral Z scores of the patients were -1.00 and -0.49, respectively. Mean BMD for distal radius was 0.239 g/cm2. Seven patients had a marked BMD decrease, their femoral and/or lumbar Z scores were below -1. Four cases had a pH lower than 7.35. In five patients, a HCO3 level less than 19 mmol/l was detected, four of them had an augmentation. Chloride measurements were slightly increased in six patients and alkaline phosphatase levels in five cases. Reduced GFR values were detected in two patients. There were no significant difference in laboratory values, in percentile height, and weights, in BMDs of femur, vertebra, forearm nor were any differences noted in age/bone age ratios in patients with augmentation when compared with those who had no augmentation. We found varying alteration in bone mineral density and HCO3 levels in patients with bladder exstrophy. Patients with bladder exstrophy, with or without augmentation, may develop serious growth retardation. As much as 45% of them, regardless of presence of augmentation, have an osteopenia or osteoporosis. We found a considerable difference in percentiles of heights as well as bone ages in bladder exstrophy patients when compared with normal population. We recommend close follow up of children with bladder exstrophy for linear growth, development of osteopenia, and bone ages.

Abstract
BACKGROUND AND PURPOSE The oropharyngeal airways are smaller in those who snore than in those who do not. We sought to determine which soft-tissue component surrounding the airways contributes to upper airway narrowing in those who snore. METHODS Ten control subjects and 19 snoring patients underwent CT, with 2-mm-thick axial sections obtained every 0.6 seconds during the respiration cycle at the same oropharyngeal level. We selected two sections with the widest and narrowest parts of the oropharyngeal airway to measure the anteroposterior and lateral dimensions of the airway and the thickness of the bilateral parapharyngeal fat pads, pterygoid muscles, and parapharyngeal walls. Mean values were calculated for each phase. For each subject, differences were calculated by subtracting the values in narrowest phase from those in the widest phase. RESULTS Changes in airway dimension (P < .05) and lateral parapharyngeal wall thickness (P < .01) were significantly different between snorers and control subjects. Changes in parapharyngeal wall thickness and transverse oropharyngeal airway diameter changes were significantly related (P < .01) in those who snored but not in control subjects. CONCLUSION Airway narrowing predominantly occurs in the lateral dimension in people who snore. Changes in the lateral pharyngeal wall are more important than the parapharyngeal fat pads in airway calibration. Narrowing of the upper airway area at the end of the expirium and the beginning of the inspirium is thought to be the cause of snoring and due to augmented muscle mass and prolonged laxity rather than inadequate activation of the pharyngeal dilating muscles.

Abstract
Twenty-four patients with hypoxic-ischemic encephalopathy were examined with serial magnetic resonance imaging up to 4 years of age. Magnetic resonance imaging studies were performed in the neonatal period, at the fourth month and the fourth year of age, and the findings were compared with the patients' neurodevelopmental outcome at the fourth year of age. Periventricular signal alterations and deep gray matter involvement were usually evident in the initial magnetic resonance imaging studies, and encephalomalacia, periventricular leukomalacia, and atrophy were the common findings on follow-up magnetic resonance imaging studies. In the patients with hypoxic-ischemic encephalopathy, some correlation between magnetic resonance imaging findings and neurodevelopmental outcome was recognized. The patients with deep gray matter involvement on the initial magnetic resonance imaging had a poor prognosis, and the ones with normal magnetic resonance imaging findings had a favorable neurodevelopmental outcome. On the follow-up magnetic resonance imaging findings, encephalomalacia and periventricular leukomalacia were associated with poor neurodevelopmental outcome. In predicting the neurologic outcome at 4 years of age, magnetic resonance imaging findings of the neonatal period had the highest negative predictive value, whereas magnetic resonance imaging findings at 4 months of age and 4 years of age had the highest positive predictive value.

Abstract
OBJECTIVE The aim of this study was to investigate gallbladder motility in children with Down syndrome by measuring gall-bladder volume and contraction index. METHODS This study, performed between January 2001 and December 2002 at the Ondokuz Mayis University, School of Medicine, Department of Paediatric Neurology, Samsun, Turkey, included 21 patients with Down syndrome (study group) and 22 healthy children (control group). After an 8-hour fast, gallbladder diameters in both groups were measured in length, width, and height by ultrasonography before and 30 minutes after a test meal. The volume of gallbladder before and after a test meal was determined, and the contraction index was calculated. Blood triglyceride and cholesterol levels were measured, and 5-hydroxyindoleacetic acid (5-HIAA) levels in urine were determined. RESULTS Mean gallbladder volume before test meal in the study group and controls was 8,412.4 +/- 5,174 mm and 16,516.8 +/- 6,796.1 mm (P < 0.001), respectively. The mean contraction index of the study group was 41.2% +/- 19.4% and of controls, 75.0% +/- 12.3% (P < 0.001). The mean triglyceride level of the study group was significantly higher than controls (P < 0.05). The mean urine 5-HIAA level of the study group was lower than controls (P < 0.05). CONCLUSION CI was lower in patients with Down syndrome, suggesting gallbladder hypomotility. Hypomotility may be a feature associated with the high prevalence of gallstones in Down syndrome.

Abstract
The aim of this study was to compare the efficacy of prophylactic trimethoprim-sulfamethoxazole (TMP/SMZ), cefprozil and cephadroxil treatments in children who have recurrent urinary tract infection, but no urinary tract pathology. After acute urinary tract infections (UTIs) were treated, the patients were divided into 3 groups randomly and TMP/SMZ was given to 21 patients, cephadroxil was given to 25 patients and cefprozil was given to 34 patients for 3 months--one dose at night. All patients were followed for 6 months following prophylaxis. The frequency of symptomatic UTIs among groups during prophylaxis was not statistically different, however the number of symptomatic UTIs in the cephadroxil group was lower than the other groups. Asymptomatic bacteriuria episodes were detected in TMP/SMZ and cefprozil groups, whereas no asymptomatic bacteriuria episodes were seen in the cephadroxil group. The number of patients with symptomatic UTI during the follow-up period was not different between groups, however all the asymptomatic bacteriuria episodes were encountered in the cefprozil group. In conclusion, in this study cephadroxil was found to be slightly superior to TMP/SMZ and cefprozil in preventing asymptomatic bacteriuria episodes and symptomatic UTIs in children with recurrent UTI and normal urinary tract system.

Abstract
PURPOSE The aim of this study is to investigate the diagnostic value of unenhanced helical computed tomography in choledocholithiasis. MATERIALS AND METHODS Unenhanced helical computed tomography was performed in 37 patients with findings of obstructive jaundice and suspicion of choledocholithiasis. Results were classified as choledocholithiasis and others. In 35 patients the results were confirmed by endoscopic retrograde cholangiopancreatography, and in 2 by surgery. RESULTS Choledocholithiasis was detected by unenhanced helical computed tomography in 16 patients. In 13 patients, choledocholithiasis was proven by endoscopic retrograde cholangiopancreatography and in one patient by surgery. Unenhanced helical CT had 93.3% sensitivity and 90.9% specificity in the diagnosis of choledocholithiasis. CONCLUSION Unenhanced helical computed tomography may be used as a noninvasive, reliable, and rapid alternative diagnostic method in the diagnosis of choledocholithiasis.

Abstract
SUMMARY Most coil-induced aneurysmal ruptures during endovascular treatment occur in small, recently ruptured aneurysms, and after placement of at least one coil. In cases where the distal part of the microcatheter cannot move back due to its straightness and tightness, the last coil deployed may advance towards the aneurysmal wall through intercircles of deposited coils. To solve this problem, after complete occlusion of the sac is obtained, the microcatheter is slightly withdrawn until the tip of the catheter is placed in the neck, and then the neck is occluded with the appropriate coil.

Abstract
PURPOSE We aimed to determine the effect of informing patients about side effects of the contrast material on the level of patients' anxiety. MATERIALS AND METHODS Two hundred-ninety seven patients undergoing computed tomography examination were enrolled in the study. Patients were grouped in three categories: (1) patients informed about adverse effects of contrast material and waiting for i.v. contrast material injection, (2) uninformed patients waiting for i.v. contrast material injection, (3) uninformed patients undergoing unenhanced CT examination. All patients were requested to complete a questionnaire including a standard anxiety test. The results were compared statistically. RESULTS The mean anxiety scores calculated by variant analysis were 39.2 +/- 11.7, 42 +/- 10.4, and 38.6 +/- 9.5 in groups 1, 2, and 3, respectively. No statistically significant difference was found between the anxiety scores of the 3 groups. CONCLUSION Informing patients about the adverse effects of the contrast material does not affect their anxiety level.

Abstract
Maxillary myxoma is a rare benign mesenchymal tumor of unknown etiology. Although odontogenic myxomas are benign and nonmetastasizing tumors, they are locally invasive and have a propensity to recur if incompletely resected. We report a case of odontogenic myxoma involving the anterior part of the maxilla and discuss the role and findings of radiologic imaging.

Abstract
OBJECTIVES To assess the prevalence of cysts in the epididymis, seminal vesicles, prostate, and testes of patients with autosomal dominant polycystic kidney disease (ADPKD) and determine their clinical significance. Extrarenal cystic involvement is a well-known manifestation of ADPKD. Although a few reports exist about cysts in the epididymis, seminal vesicles, prostate, and testes, the true prevalence of cysts in these organs is not well known. METHODS A prospective study, consisting of 104 male patients and 62 male controls, was designed at three medical centers to evaluate the prevalence of epididymal, seminal vesicle, prostatic, and testicular cysts in patients with ADPKD by abdominal, transrectal, and scrotal ultrasound examinations. RESULTS Among the 104 patients, epididymal cysts were present in 19 (18%), seminal vesicle cysts were present in 41 (39%), and prostatic cysts were present in 7 patients (7%); the proportion in the control group was 24% (P >0.05), 2% (P <0.01), and 5% (P >0.05), respectively. Testicular cysts were detected in only 3 control patients. Of the 104 patients, 96 were married, and primary infertility was present in 5 patients (5%). CONCLUSIONS We suggest that seminal vesicle cysts are frequent in ADPKD; epididymal cysts are not uncommon in ADPKD, but the frequency is not higher than in the control group; ADPKD should be looked for in patients with seminal vesicle cysts; and additional studies are necessary to evaluate the association between epididymal and seminal vesicle cysts and infertility in patients with ADPKD.

Abstract
Proboscis lateralis is a rare craniofacial anomaly. It consists of a soft, trunk-like process that originates from the medial portion of the orbital roof and it may be accompanied by a number of facial and cerebral anomalies. The characteristics and relationship of the lesion to adjacent structures should be known, and associated anomalies should be detected before surgical correction. The patient should undergo neuroimaging studies besides clinical evaluation to obtain this information in detail. The neuroimaging findings of only one previous case are available in the literature. We report two cases of proboscis lateralis evaluated by CT and MRI before corrective surgery.

Abstract
We reported five cases of Dyke-Davidoff-Masson syndrome (DDMS) with different clinical and radiological findings. The evaluated parameters were the location of the lesions, midline structural shift effect, pathological and morphological changes on the ipsilateral calvarium, paranasal sinuses and mesencephalon, presence of compensatory contralateral hypertrophy. With the help of both magnetic resonance (MR) and computerized tomography (CT) images, changing degrees of all the evaluated parameters were observed in all five of our patients. In conclusion, no relationship was found between parenchymal and calvarial changes and between the time after onset of the disease and amount of the morphologic and pathological changes.

Abstract
The aims of this study are to demonstrate the ability of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) in the diagnosis and evaluation of vascular involvement in Behçet's disease. Twelve patients with vascular involvement due to Behçet's disease were included in this study. We believe that MRI and MRA are safe and noninvasive methods that can be used to confirm and monitor vascular Behçet's disease.

Abstract
Osteomas of paranasal sinuses are usually asymptomatic. When enlarged, they may cause serious complications. We report a case of huge frontoethmoidal osteoma associated with brain abscess. If an osteoma associated with an intracerebral pathology is detected, it should be remembered that this could have been a complication of the osteoma and a detailed radiological examination should be performed to show the extent of the osteoma and to confirm any defect at the posterior wall of the sinus which may lead intracerebral complications. Such an osteoma should be operated after the abscess was resolved and patient became stable neurologically.

Abstract
A wandering spleen is a rare clinical entity resulting from congenital maldevelopment or acquired laxity of the spleen's suspensory ligaments; it may result in torsion of the spleen. We report the gray-scale sonographic, power Doppler sonographic, and CT findings in a case of wandering spleen torsion. The gray-scale sonograms showed a displaced spleen that appeared as a homogeneous, hypoechoic mass suggestive of an enlarged, ectopic spleen in the central abdomen. Power Doppler sonograms showed no blood flow in the parenchyma or hilum of the spleen and were consistent with torsion and infarction in the spleen. Contrast-enhanced CT scans showed a homogeneous, unenhanced mass that was diagnosed as a torsioned wandering spleen. The hilar vessels of the spleen were also unenhanced.

Abstract
Behçet's disease is a multisystem disorder characterized by recurrent aphtous ulcers of mucosal membranes, skin lesions, and vasculitis. The prevalence of vascular involvement is about 25% and this is the leading cause of death in Behçet's disease. Jugular vein involvement is an unusual manifestation of Behçet's disease. Medical insertion of needles into veins or arteries can induce thrombosis or aneurysms. Thus, diagnostic studies or therapy can aggravate the disease and even be fatal. We report a patient with Behçet's disease and rare internal jugular vein thrombosis. We also demonstrate the ability of noninvasive magnetic resonance imaging and magnetic resonance angiography to aid in the diagnosis and evaluation of vascular involvement in Behçet's disease, without risking iatrogenic complications.

Abstract
Pulmonary alveolar microlithiasis is an inherited disorder of unknown etiology. It is a rare disease characterized by calcified intraalveolar microgranules. Several hypotheses on the etiopathogenesis have been put forward, such as increased intestinal calcium resorption and retention. This case report of pulmonary alveolar microlithiasis is associated with punctate calcifications in the seminal vesicles.
