background: previous anatomic and radiological studies have described the relationship of the clavicle to major neurovascular structures in healthy subjects. we were curious about this relationship in patients with a clavicle fracture and if it is different from non-fractured clavicles.   methods: we retrospectively identified all patients with a clavicle fracture between july 2001 and october ...

fibrovascular polyps are rare, pedunculated, tumor-like lesions that are usually found in the esophagus; occurrence in the stomach is very rare. to our knowledge, sonographic and ct findings of a fibrovascular polyp in the stomach have never been reported. here, we report a case of a fibrovascular polyp that was identified in the gastric antrum and prolapsed into the duodenal bulb. sonography r...

primary pleuropulmonary synovial sarcomas are rare soft tissue malignancies; combined metastatic involvement of the heart is extremely rare. in this case report, a 17-year-old female presented with a history of chest pain. chest radiographs revealed a round mass in the left upper hemithorax, and computed tomography (ct) showed a well-defined heterogeneous enhancing mass abutting the pleura. a c...

a mobile caecum and ascending colon is an uncommon congenital disorder, and it is even rarer as the cause of an acute abdomen during childhood. this report presents the case of a 6-year-old boy with acute gangrenous appendicitis with a mobile caecum and ascending colon. data from the surgical course, as well as laboratory and imaging studies, were acquired and carefully examined. emergency ultr...

plagiocephaly (oblique skull) is premature fusion of one of the coronal sutures. frontal plagiocephaly is a rare congenital deformity in the skull that is the most complicated form of craniosynostosis to treat. examination of all sutures is necessary for diagnosis of craniosynostosis in this article, a 10-month-old, healthy girl with deformity of the right forehead and orbit that is caused by f...

root canal anatomy diversity and aberrations are common especially in permanent dentition. a thorough understanding of the basic root canal anatomy and its diversities are necessary for successful endodontic treatment. mandibular second premolars are usually single-rooted and have one root canal. incidence of three separate root canals in this tooth is quite rare and taurodontism with three sep...

conclusions headache, seizure, and trauma are the main reasons for ct scan requests. about 12% of the brain ct scans were abnormal. being knowledgeable about the indications of imaging, unnecessary imaging can be prevented, and consequently, its risks can be minimized. patients and methods in the present case series, demographic information and ct scan reports of 167 patients referred to taba r...

In this series we present a quiz about identification of salient and important anatomical landmarks present at a given level on the computed tomography (CT) image. The representative image is followed by further images showing examples of various commonly encountered pathologies that can be seen at this level in clinical practice. Readers are expected to identify highlighted structures in all t...

objectives: accurate localization of the inferior alveolar canal (iac) is extremely important in some dental treatments. anatomical variation of the canal means that it can be difficult to locate. the purpose of this study was to assess the relationship of the gonial angle (ga) size and iac position using cone beam computed tomography (cbct). materials and methods: in this in vitro study, 61 dr...

the ribs are essential structures of the osseous thorax that provide certain significant information and aid interpretation of radiologic images in daily routine practice. intrathoracic rib is a rare congenital anomaly that is usually discovered incidentally, but may cause in vain interventions in case of being unaware. we herein report an intrathoracic rib in a girl whose chest x-ray was stran...
