Angiographic Features of Unilateral Nonbifurcating Cervical Carotid Artery: A Case Report
은나래,이승구 대한영상의학회 2015 대한영상의학회지 Vol.73 No.2
Nonbifurcating cervical carotid artery is a rare anomaly of the common carotid artery (CCA), in which the branches of the external carotid artery (ECA) arise directly from the CCA or proximal internal carotid artery without bifurcation, and therefore there is no proximal main trunk of the ECA. We report a unilateral nonbifurcating cervical carotid artery of a 67-year-old woman, incidentally found during cerebral aneurismal treatment.
Balloon-Supported Passage of a Stent-Graft into the Aortic Arch

A 62-year-old man was admitted, and thoracic endovascular aortic repair (TEVAR) procedure was performed to treat an accidentally detected aortic aneurysm, which was 63 mm in diameter. While performing TEVAR, the passage of the stentgraft introducer system was impossible due to the prolapse of the introducer system into a wide-necked aneurysm; this aneurysm was located at the greater curvature of the proximal descending thoracic aorta. In order to advance the introducer system, a compliant balloon was inflated. Thus, we created an artificial wall in the aneurysm with this inflated balloon. Finally, we were able to advance the introducer system into the target zone.

Purpose: The goal of this study was to assess the clinicopathologic and ultrasonographic featuresof thyroid nodules with nondiagnostic results on repeat ultrasonography (US)-guided fineneedleaspiration biopsy (FNAB) according to size and the number of suspicious findings and todetermine the proper management of nodules with consecutive nondiagnostic results. Methods: This retrospective study included 297 nodules with nondiagnostic results on repeatFNAB that were evaluated by US over the course of at least 12 months of follow-up, a follow-upbiopsy, or an operation. We compared clinical and US variables between benign and malignantnodules in thyroid nodules with repeat nondiagnostic results. Results: The comparison of benign and malignant nodules with repeat nondiagnosticresults revealed that age, marked hypoechogenicity, irregular or microlobulated margins,microcalcifications, and nonparallel shape were significantly associated with malignancy. Multivariate logistic regression analysis in malignant nodules revealed that microcalcificationsand irregular or microlobulated margins were independently associated with malignancy. Amongthem, only irregular or microlobulated margins were independently significant as a predictor ofmalignancy in repeatedly nondiagnostic nodules measuring >10 mm. Using receiver operatingcharacteristic analysis, the best cutoff value for the “number of suspicious findings” betweenbenign and malignant nodules was three in nodules of all sizes, three in nodules measuring ≤10mm, and two in nodules measuring >10 mm. Conclusion: Irregular or microlobulated margins may be the most frequent US features inrepeatedly nondiagnostic nodules >10 mm. The presence of “two or more suspicious findings”can be used as the cutoff for distinguishing benign and malignant nodules.

Purpose : Intramedullary spinal lesions in the conus medullaris (CM), including tumors and vascular lesion, are rarelyreported. We reported various MR features of intramedullary spinal cord lesions involving the CM including ependymoma,hemangioblastomas, dermoid cyst, ventriculus terminalis and spinal AVF and tried to discuss them for differentialdiagnosis. Materials and Methods: Six patients (male: female = 4:2, mean age = 44.3 year old) were enrolled from the clinical databaseof our institute from 2004 to 2010 and their radiological images and clinical symptoms were reviewed retrospectively. All patients had taken initial and postoperative MRI with contrast enhancement using gadopentate dimeglumine (Gd-DTPA). These images were analyzed by tumor size, location, signal intensity relative to the spinal cord, vascular flow voids,syrinx or cyst, edema and enhancement pattern. Results: Contrast enhancement was seen in all intramedullary masses. An eccentric enhancing nodule was noted in twohemangioblastomas and unusual peripheral rim enhancement with septation was seen in ventriculus terminalis. Patchyenhancement of the CM was observed in spinal arteriovenous fistula (AVF). Extensive cord edema adjacent to theintramedullary lesions was seen in four cases and syrinx was noted in three cases. Vascular signal voids were found in twohemangioblastomas and one spinal AVF. Conclusion: In evaluation of intramedullary spinal lesions in the CM, it is necessary to consider these unusual MR findingsand discriminate various pathologies with prudence and caution.
