    ABSTRACT: We describe two right-sided diverticulitis cases that presented with marked right iliac fossa tenderness with guarding and rebound and laboratory parameters resembling acute appendicitis. The imaging findings suggested diverticulitis in both cases. One of the patients underwent surgery and the other one was followed up with medical treatment. Awareness of these imaging findings may aid in the diagnosis of right-sided diverticulitis, which is frequently misdiagnosed and mistreated. © 2012 Wiley Periodicals, Inc. J Clin Ultrasound, 2012.

    ABSTRACT: Objective: To determine the frequency and characteristics of bifid mandibular condyle (BMC) using computed tomography (CT) evaluation. Study Design: A retrospective study was carried out using the CT records of 550 patients referred to the Medical School of Erciyes University (Kayseri, Turkey) between 2007 and 2010. T-tests were used to compare frequency of BMC between the left and right sides and between female and male patients. Statistical analysis was performed using SPSS software and a chi-squared test. Results: Of the 550 Patients, 10 patients (1.82%) were found to have BMCs. Five patients were female (50%) and five were male (50%). Of these 10 patients, 7 (70%) had unilateral and 3 (30%) had bilateral BMCs. As a result, a total of 13 BMCs were found in 10 patients. No statistically significant differences were found between either the right- and left-sided BMCs or between female and male patients (p >.05). Conclusions: To our knowledge, this is the first retrospective study investigating the prevalence and characteristics of BMC using computed tomography. Although BMC is an uncommon anomaly, it may be a more frequent condition in the Turkish population. Further studies and research on the orientation of duplicated condylar heads should be carried out. Key words:Computed tomography, bifid condyle, double-headed condyle, orientation, frequency.

    ABSTRACT: To investigate the frequency and characteristics of the mandibular accessory buccal foramen (ABF) with CT. A retrospective study was carried out using the CT records of 504 patients referred to the Erciyes University Medical School (Kayseri, Turkey) between 2007 and 2010. Presence, location, diameter, area and number of ABFs and their continuity with mandibular canal and distance to the mental foramen were evaluated using axial, sagittal and three-dimensional CT images. Statistical analysis was performed using SPSS® v. 15 (SPSS Inc., Chicago, IL), and t-tests were used for statistical analysis. 14 ABFs were observed in 10 (2%) of 504 patients. The frequency of ABFs was found to be 2.6% in males and 1% in females. The mean distance between the ABF and the mental foramen was 5.0 mm [standard deviation (SD) ± 2.48]. The mean long axis of the ABFs was 1.4 mm (SD ± 0.4) and the mean area of them was 1.5 mm(2) (SD ± 0.8). The mean area of the mental foramen on the side with the ABF was 4.1 mm(2) (SD ± 2.71). This study presents a relatively lower frequency of ABFs than that in the literature. These foramina could have more complex neurovascular structures than was previously thought. Thus, in special cases where a direct surgical exploration during the planned surgery is not indicated, CT or cone beam CT examination to determine the possible presence of ABFs may be indicated.

    ABSTRACT: Our purpose was to evaluate the effectiveness of bedside sonography (US) in the detection of pneumothorax secondary to blunt thoracic trauma. In this prospective study, 240 hemithoraces of 120 consecutive patients with multiple trauma were evaluated with chest radiographs (CXR) and bedside thoracic US for the diagnosis of pneumothorax. CT examinations were performed in 68 patients. Fifty-two patients who did not undergo CT examinations were excluded from the study. US examinations were performed independently at bedside by two radiologists who were not informed about CXR and CT findings. CXRs were interpreted by two radiologists who were unaware of the US and CT results. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CXR and US were calculated. One hundred thirty-six hemithoraces were assessed in 68 patients. A total of 35 pneumothoraces were detected in 33 patients. On US, the diagnosis of pneumothorax was correct in 32 hemithoraces. In 98 hemithoraces without pneumothorax, US was normal. With US examination, there were three false-positive and three false-negative results. The sensitivity, specificity, positive predictive value, negative predictive value, and overall accuracy of US were 91.4%, 97%, 91.4%, 97%, and 97%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of CXR were 82.7%, 89.7%, 68.5%, 95%, and 89.5%, respectively. Bedside thoracic US is an accurate method that can be used in trauma patients instead of CXR for the detection of pneumothorax. © 2012 Wiley Periodicals, Inc. J Clin Ultrasound, 2012

    ABSTRACT: The aim of this study was to investigate the frequency of Stafne bone defect (SBD) and to describe the clinical and radiological characteristics of detected cases. A retrospective study was performed using panoramic radiographs from 34 221 patients undergoing dental treatment in the Department of Oral and Maxillofacial Radiology at Erciyes University and Ataturk University, Turkey. After finding an image compatible with SBD in the radiographs, multislice CT (MSCT) on seven patients and cone beam CT (CBCT) on six patients were performed to confirm the diagnosis. Of the 34 221 patients, 29 (0.08 %) had SBDs, of whom 4 were female (13.8%) and 25 were male (86.2 %). The age range of patients with SBD was 18-77 years (mean age 49.6 years). SBD was found in the lingual molar region in 28 patients and in the lingual canine-premolar region of the mandible in 1 patient. The contour of the concavities on CT images (MSCT and CBCT) was detected. The MSCT revealed glandular tissue within the defects. According to our results, SBD is an uncommon anomaly. Examination of MSCT images supports the presence of aberrant submandibular glands within these mandibular defects, suggesting that pressure from submandibular gland tissue had caused the SBD, as generally thought. Both CBCT and MSCT can provide adequate support for the detection of SBDs. The CBCT could be suggested as the most suitable non-invasive diagnostic modality for this bony configuration of the mandible since it provides a lower radiation exposure dose than MSCT.

    ABSTRACT: Polyarteritis nodosa (PAN) is a necrotizing inflammatory vasculitis of small- and medium-sized muscular arteries. Multiple organs, especially the kidney, skin, peripheric nerves, striated muscles, and intestine, are affected. In this case report, a patient with renal and hepatic involvement and axillary and brachial artery aneurysm resulting in shoulder hematoma and pain due to underlying PAN is presented.

    ABSTRACT: OBJECTIVE: Our aim was to describe the technique of direct CT venography and to describe various forms of venous anomalies detected with CT venography in patients with Klippel-Trénaunay syndrome. CONCLUSION: MDCT is helpful for visualizing the full length of extremities and for evaluating length and thickness on one image.
