RESUMO
BACKGROUND: Hyperdense middle cerebral artery sign is an appearance of the middle cerebral artery on non-contrast-enhanced computed tomography. Embolic occlusion of the pulmonary arterial system is referred to as pulmonary embolism. When pulmonary embolism coexists with a patent foramen ovale, increased pressure in the right atrium may result in widening of the foramen and consequently, cause serious conditions due to paradoxical embolus. Coexistence of hyperdense middle cerebral artery sign and pulmonary thromboembolism is very rare in the literature. CASE REPORT: We presented a 60-year-old female patient who had both hyperdense middle cerebral artery sign and pulmonary thromboembolism. CONCLUSIONS: To our knowledge, togetherness of hyperdense MCA sign and pulmonary thromboembolism is extremely rare in the literature. In our case, we found both pulmonary embolism due to DVT and paradoxical embolism due to existing patent foramen ovale.
RESUMO
OBJECTIVE: This preliminary study aimed to evaluate changes in apparent diffusion coefficient (ADC) values of the testes in patients presenting with varicocele. SUBJECTS AND METHODS: This cross-sectional study included 25 consecutively recruited patients with varicocele and 25 healthy control volunteers. The ADC values were measured in all participants. Kolmogorov-Smirnov tests were used to test the normality of the data distributions, and the data were expressed as arithmetic means and SDs. A one-way analysis of variance with a post hoc Bonferroni test was used to analyze normally distributed continuous data. Independent sample Student t tests were used to compare continuous variables between two groups. Furthermore, a Pearson correlation coefficient analysis was used to examine the association of venous diameters with mean ADC values in patients with varicocele. A two-sided p value < 0.05 was considered statistically significant. Sensitivities, specificities, and areas under the curve were calculated for the ADC values. RESULTS: The ADC values associated with the ipsilateral testicular parenchyma of patients with varicocele were found to be lower than those of healthy volunteers. Moreover, the ADC values of the contralateral testicular parenchyma in patients with varicocele were also lower than those of healthy volunteers. The sensitivity and specificity of ADC values were 90% and 96%, respectively, for patients with varicocele and 89.5% and 96% for healthy volunteers. The mean ADC values were significantly negatively correlated with venous diameter. CONCLUSION: The measurement of testicular ADC values may be used as a diagnostic indicator in the detection of testicular fibrosis.

Joubert syndrome is a rare disease characterised by clinical and radiological findings. Among the classic clinical findings of JS are hypotonia, ataxia, mental-motor retardation, respiratory and opthalmological findings. The paediatric cases included in the study comprised nine patients. There was familial consanguinty in seven cases. Clinically, all cases had mental-motor retardation and hypotonia. Episodic hyperpnoea attacks were observed in one case. Facial dysmorphism was the most common additional systemic anomaly and four cases had additional opthalmic findings. Brain MRI examination revealed that all cases had molar tooth sign, bat-wing appearance and vermian cleft. The majority of cases also had vermian hypoplasia. Cerebellar folial disorganisation was observed in approxiamtely half of the cases. Three cases had corpus callosum anomaly and atretic occipital encephalocoele. No pathology was determined in other organs. This study aimed to evaluate the clinical and radiological findings of 9 patients diagnosed with Joubert syndrome.

PURPOSE: Bicycling is a well-liked sporting activity in which many children participate, and bicycle accidents are one of the most common causes of abdominal injuries in children. We evaluated the characteristics and outcomes of abdominal injuries due to bicycle accidents in children. PATIENTS AND METHODS: This study was carried out retrospectively on children at the Department of Pediatric Surgery who were hospitalized for abdominal injury due to a bicycle accident, from 2008 to 2012. Abdominal injury-related bicycle accidents were evaluated with respect to patient characteristics, clinical presentation, management strategy, and outcome. RESULTS: Fifty-nine patients were hospitalized for abdominal injuries related to a bicycle accident. The mean age of the patients was 11.48 ± 3.6 years. Most patients had an imprint of the handlebar edge on their abdomen. The most common abdominal organ injury due to a bicycle accident was laceration of the liver. Most patients were treated conservatively. Surgery was performed in 14 (24.1 %) patients. Hospital stay was 1-68 (mean 4.34 ± 11.6) days. CONCLUSIONS: Abdominal injuries following a bicycle accident are frequent, serious, and preventable. Most patients were treated conservatively. Bicycle injuries can be prevented.

Moyamoya disease is a cerebrovasculopathy of unknown etiology during the course of which the main and terminal veins of the internal carotid artery undergo progressive vein occlusion. Leigh syndrome is a mitochondrial encephalomyopathy that occurs due to "cytochrome c oxidase deficiency" characterized by psychomotor retardation, difficulty in eating, seizures, hypotonia, respiratory disorders and high lactate levels. Many diseases and syndromes have been defined that are associated with Moyamoya disease. To the best of our knowledge, the association of moyamoya disease with Leigh syndrome has not been defined as yet. In this study, the clinical and imaging results of a 3-year-old male child displaying the association of Moyamoya disease and Leigh syndrome are presented.

Brucellosis is an endemic disease in Turkey, and testicular abscess is a rare and frequently misdiagnosed complication of brucellosis. In the literature there are only seven reported cases, and all were treated with both medical and surgical therapy. We report a case of brucellar testicular abscess treated with medical therapy only. Although the patient recovered clinically at the end of 6 weeks, the regression of the testicular lesion could not be observed until after 5 months.

BACKGROUND: Respiratory and cardiovascular diseases are the most common causes of death in children with cerebral palsy. OBJECTIVE: To evaluate sonographic carotid intima-media thickness, an early marker of atherosclerosis, in children with cerebral palsy and in healthy controls. MATERIALS AND METHODS: One hundred children with cerebral palsy (65 boys), mean age 6.2 (SD, 2.1) years, and 35 age-matched and sex-matched healthy controls were included. Common carotid artery intima-media thickness was measured sonographically. Differences between patients and controls were evaluated with an independent samples t-test. RESULTS: Age, sex distribution and levels of serum lipids were comparable between patients and controls. Average, right and left carotid artery intima-media were thicker in patients compared with controls (mean ± SD, 0.61 ± 0.13 mm vs 0.40 ± 0.03 mm; 0.61 ± 0.14 mm vs 0.40 ± 0.03 mm; 0.61 ± 0.13 mm vs 0.40 ± 0.03 mm, respectively; all P < 0.001). CONCLUSION: Carotid intima-media is sonographically thicker in children with cerebral palsy compared with healthy controls, which may express an increased risk of atherosclerotic diseases.

OBJECTIVE: To investigate the effects of increased pressure due to the accumulated fluid around testis in hydrocele on testis diffusion and whether this effect (if any) is correlated with the amount of fluid and duration of hydrocele. PATIENTS AND METHOD: 49 patients with unilateral hydrocele were evaluated by magnetic resonance diffusion-weighted imaging. RESULTS: In the study group, while the apparent diffusion coefficient (ADC) values of the testicles with hydrocele differed significantly before and 3 months after the hydrocelectomy (p = 0.001), the ADC values of the testicles without hydrocele were not statistically different (p = 0.101). There was a significant negative correlation between the ADC values of the testicles with hydrocele and the amount of the liquid aspirated during the hydrocelectomy (r = -0.615, p = 0.001). There was no correlation between the ADC values of testis and the duration of hydrocele (r = -287, p = 0.156). This is supported by the findings of the present study of reduced ADC values of testis, meaning reduced diffusion of the testis, with an increasing amount of fluid. CONCLUSION: The pressure of the fluid was suggested to show a mechanical effect that plays an important role in the dysfunction of the testis. The possible dysfunctions of the testicular tissue suggest that they may have a negative effect on fertility.

PURPOSE: The risk of atherosclerosis is increased in several rheumatological disorders, but any such risk remains unproven for ankylosing spondylitis. Since carotid intima-media thickness is an indicator of early atherosclerosis, and the paraoxonase (PON1) enzyme has antioxidant activity to prevent LDL oxidation, we aimed to identify: 1) the relationship between carotid intima-media thickness (CIMT) and serum paraoxonase (PON1) activity in ankylosing spondylitis (AS) patients; and 2) the possible differences in CIMT in AS patients versus age-matched, healthy controls. METHODS: Forty-five AS patients (36.8±9.8 years, 36 males, 9 females) and 30 controls (35.9±10.2 years, 23 males, 7 females) were recruited consecutively. Serum PON1 activity and CIMT were measured. The Bath Ankylosing Spondylitis Metrology Index (BASMI), Bath Ankylosing Spondylitis Functional Index (BASFI), Bath Ankylosing Spondylitis Radiologic Index (BASRI) and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) were used to identify relationships between these clinical indices and levels of CIMT and PON1. RESULTS: Mean CIMT was significantly increased in AS patients relative to controls (0.49±0.06 mm vs. 0.59±0.07 mm; p < 0.0001). Conversely, serum PON1 activity was decreased (199.1±60.3 U/L vs. 96.7±29 U/L; p < 0.0001). PON1 activity was negatively correlated with CIMT (r = -0.557, p = 0.0001). Disease duration was positively correlated with CIMT (r = 0.542, p = 0.0001) and negatively correlated with PON1 (r = -0.649, p = 0.0001). On multivariate analysis, disease duration and serum PON1 activity were found to be independent predictors of CIMT (R2 = 0.687, p = 0.0001). CONCLUSIONS: In conclusion, significantly increased CIMT and decreased PON1 activity suggest a relationship between atherosclerosis and AS: a relationship that is strongly correlated with disease duration.

BACKGROUND: Osteomyelitis is a common complication in the diabetic foot that can conclude with amputation. The purpose of this study was to evaluate the role of diffusion-weighted magnetic resonance imaging (DWI) in the diagnosis of osteomyelitis in diabetic foot ulcer (DFU). METHODS: Thirty patients with type 2 diabetes mellitus and a DFU were enrolled. Both DWIs and conventional MRIs were obtained. Apparent diffusion coefficient (ADC) measurements were made by transferring the images to a workstation. The measurements were made both from bone with osteomyelitis, or nearest to the injured area if osteomyelitis is not available, and from the adjacent soft tissue. RESULTS: The patients comprised nine women (30%) and 21 men (70%) with a mean age of 58.7 years (range, 41-78 years). The levels of ADC were significantly low (P = .022) and the erythrocyte sedimentation rates were significantly high (P = .014) in patients with osteomyelitis (n = 9) compared with patients without osteomyelitis (n = 21). The mean ± SD bone ADC value (0.75 ± 0.16 × 10-3 mm2/sec) was significantly lower than the adjacent soft-tissue ADC value (0.90 ± 0.15 × 10-3 mm2/sec) in patients with osteomyelitis (P = .04). CONCLUSIONS: It is suggested that DWI contributes to conventional MRI with short imaging time and no requirement for contrast agent. Therefore, DWI may be an alternative diagnostic method for the evaluation of DFU and the detection of osteomyelitis.

Horseshoe kidney (HSK) is the most common fusion anomaly of kidneys. Diagnosis of horseshoe kidneys is made by the demonstration of an isthmus or band of renal tissue between the lower poles of the kidneys. Connection between the upper poles of the kidneys is extremely rare. Several types of skeletal anomalies can be seen concomitantly with HSK. In our present case, where the patient was a 3-year-old male, the connection of renal tissue was located between the upper poles of the kidneys. Furthermore, there was an accompanying spina bifida and Gibbus deformity secondary to anterior hypoplasia of the T10 vertebral body.

OBJECTIVE: This preliminary study aimed to evaluate whether there are changes in the apparent diffusion coefficient (ADC) values of the brain in patients presenting with Eisenmenger syndrome (ES). METHODS: This cross-sectional study included 10 consecutively recruited patients with ES and 10 healthy control subjects. In the patients and controls, eight distinct neuroanatomical locations were selected for analysis. Quantitative measurements of ADC values of the frontal white matter (FWM), occipital white matter, lentiform nucleus (LN), thalamus, frontal cortex, anterior and posterior limbs of the internal capsule and caudate nucleus were measured. Statistical analysis was performed using SPSS® (IBM Corp., New York, NY; formerly SPSS Inc., Chicago, IL) for Windows v. 20. Data were presented as mean ± standard deviation values. The Kruskal-Wallis test was used to assess differences in the ADC values of each brain location between the ES group and the control group. Statistical significance was accepted at the level of p < 0.05. RESULTS: The ADC values of the FWM and LN were significantly higher in the ES group than that in the control group. The mean ADC levels of other brain regions were not significantly different between the groups. CONCLUSION: Chronic hypoxia in patients with ES may lead to diffusion changes in the brain tissue. There is a need for further studies to assess the clinical significance of cerebral ADC values in patients with ES. Advances in knowledge: The ratio of extracellular volume to intracellular volume in the FWM and LN can be considered to be increased in patients with ES.

Encephalocele is defined as herniation of the brain tissue from a bone defect in the cranium. It may be congenital, traumatic, tumoural or develop spontaneously. Traumatic fronto-ethmoidal encephalocele is rare and should be kept in mind for patients who have suffered trauma. Early diagnosis is important in terms of preventing life-threatening complications such as meningitis. Encephalocele and cerebrospinal fluid (CSF) leakage can be easily determined with basic radiological imaging methods and clinical findings. The computed tomography (CT) and magnetic resonance imaging (MRI) findings are here presented of a case with traumatic encephalocele.
RESUMO
BACKGROUND: This study aimed to investigate the efficacy of quantitative apparent diffusion coefficient (ADC) measurement in the differential diagnosis of the uterine endometrial cavity tumors (UECT). METHODS: This study included consecutive 36 female patients with UECT. The groups were formed as follows: group 1, patients with endometrial carcinoma; group 2, patients with endometrial polyp; group 3, patients with submucosal leiomyoma; and additionally group A, patients with malignant lesion; group B patients with benign lesion. Tumoral and outer myometrial ADC values were measured and the tumor-myometrium ADC ratios were calculated in all patients. Kolmogorov-Smirnov tests were used to test the normality of the data distributions. The data were not normally distributed, and therefore, nonparametric tests were performed. The cut-off values, sensitivity, and specificity were determined by the receiver operating characteristic analysis. RESULTS: The mean ADC value and ratio of group 1 were lower than that of group 2 and 3, and the mean ADC value and ratio of group 3 were lower than that of group 2. The sensitivity and specificity for group 1, 2, and 3 were as follows: 90, 100, and 66.7 %; and 81.8, 88, and 58.8 %, respectively, in terms of the ADC values; 90, 100 and 67 %; and 77.3, 96, and 64.7 % in terms of the ADC ratios. Statistically significant differences were demonstrated between group A and B in terms of mean tumoral ADC values and ratios. Sensitivity and specificity were found to be 90 and 81.8 %, respectively, in terms of the ADC values. The sensitivity and specificity were found to be 90 and 77.3 %, respectively, in terms of the ADC ratios. CONCLUSIONS: ADC values and ratios represent a promising parameter in the determination of the tumoral lesions in patients with UECT.

OBJECTIVE: In bipolar disorder, dysregulation of mood may result from white matter abnormalities that change fiber tract length and fiber density. There are few studies evaluating the white matter microstructural changes in bipolar I patients (BD) with depressive episodes. The present study aimed to evaluate anterior corona radiata in BD patients with depressive episode using Diffusion Tensor Imaging (DTI). METHODS: Twenty-one patients with bipolar depression and 19 healthy controls were investigated and groups were matched for age and gender. Diffusion-weighted echoplanar brain images (DW-EPI) were obtained using a 1.5 T MRI scanner. Regions of interest (ROIs) were manually placed on directional maps based on principal anisotropy. Apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values of white matter were measured in the anterior corona radiata (ACR) bilaterally by diffusion tensor imaging. RESULTS: There was not a significant difference between groups of age and gender (p>0.05). Significantly lower FA was observed in bilateral ACR in bipolar patients with depression compared with healthy individuals. And there is significantly higher ADC values in the left frontal corona radiate in bipolar patients. CONCLUSION: White matter abnormalities can be detected in patients with BD using DTI. The neuropathology of these abnormalities is unclear, but neuronal and axonal loss, myelin abnormalities and reduced white matter fiber density are likely to be relevant.
RESUMO
PURPOSE: We aimed to determine the prevalence of paratracheal air cysts (PTACs) and the relationship of PTACs with emphysema and bronchiectasis through retrospective analysis of multidetector computed tomography (MDCT) findings. METHODS: MDCT findings of 1027 consecutive patients who underwent routine thorax examination between January 2012 and January 2013 were evaluated retrospectively for the presence of PTACs. Localization of the PTACs, as well as their size, shape, and relationship with the trachea were examined. Presence of emphysema and bronchiectasis was recorded, and bronchiectasis severity index was calculated when present. We randomly selected 80 patients who had no visible PTACs as the control group. The findings of patients with and without PTACs were compared. RESULTS: PTACs were determined in 82 of 1027 patients (8%), in 8.8% of females and 7.3% of males. The presence of PTACs was determined to be independent of gender (P = 0.361). Eighty-one PTACs (98.8%) were located in the right side of the trachea and 56.1% had a tracheal connection. The presence of PTACs significantly correlated with the presence and severity of bronchiectasis (P = 0.001 and P = 0.005 respectively). There was no significant relationship between the presence of PTACs and the presence of emphysema on CT images (P = 0.125). CONCLUSION: The prevalence of PTACs was determined as 8% in this study. There was significant association between PTACs and bronchiectasis.

OBJECTIVE: In recent years several techniques have been recommended for intussusception treatment. In this study, an evaluation was made of intussusception cases that presented at our clinic and had reduction applied together with saline under ultrasonography (USG) and cases, which were surgically treated. PATIENTS AND METHODS: A retrospective evaluation was made of the records of 72 cases treated for a diagnosis of intussusception between January 2010 and July 2012. Patients were evaluated demographics, clinical presentation, management strategy, during the hospitalisation and outcome. RESULTS: A total of 72 cases which consists of 44 male and 28 female with age range between 5 and 132 months were treated with a diagnosis of intussusception. USG was applied to all cases on initial presentation. As treatment, hydrostatic reduction (HR) together with USG was applied to 47 cases. Of these, the HR was unsuccessful in 13 cases. Surgical treatment was applied to 38 cases. Of these cases, ileocolic intussusception was observed in 30 cases, ileoileal in seven cases and colocolic in one case. Meckel diverticulum was determined in five of these cases, polyps in two cases, lymphoma in two cases, lymph nodule in one case and 28 cases were observed to be idiopathic. There was no mortality in any case. CONCLUSION: HR together with USG is a safe technique in the treatment of intussusception, which also shortens the duration of hospitalisation and significantly reduces the treatment costs.

PURPOSE: We aimed to evaluate the efficacy of multidetector computed tomography (CT) imaging in diagnosis of pleural exudates and transudates using attenuation values. MATERIALS AND METHODS: This retrospective study included 106 patients who were diagnosed with pleural effusion between January 2010 and June 2012. After the patients underwent chest CT, thoracentesis was performed in the first week. The attenuation values of the pleural effusions were measured in all patients. RESULTS: According to Light's criteria, 30 of 106 patients with pleural effusions had transudates, and the remaining patients had exudates. The Hounsfield unit (HU) value of the exudates (median, 12.5; range, 4-33) was significantly higher than that of the transudates (median, 5; range, 2-15) (P = 0.001). Additionally, when evaluated by disease subgroups, congestive heart failure and empyema were predictable in terms of median HU values of the pleural effusions with high and moderate sensitivity and specificity values (84.6% and 81.2%, respectively; 76.9% and 66.7%, respectively). Compared with other patients, the empyema patients had significantly more loculation and pleural thickening. CONCLUSION: CT attenuation values may be useful in differentiating exudates from transudates. Although there is an overlap in most effusions, exudate can be considered when the CT attenuation values are >15 HU. Because of overlapping HU values, close correlation with clinical findings is essential. Additional signs, such as fluid loculation and pleural thickness, should be considered and may provide further information for the differentiation.
