성인에서 발견된 장의 역회전 이상의 영상의학적 소견: 3예 보고
백현석,박원규,조재호,김종열,장재천,김재운,김금래 대한영상의학회 2009 대한영상의학회지 Vol.61 No.6
Most anomalies of intestinal rotation are detected during the postneonatal period. In adults, the diagnosis and treatment of patients with a congenital anomaly of the midgut can be difficult because of their extremely rarity. Based on embryology, anomalies of intestinal rotation can be divided into non-rotation, reversed rotation and malrotation. Reversed rotation of the midgut is the rarest of all anomalies of intestinal rotation. Although this anomaly is rare, it can be diagnosed by a detailed knowledge of embryology and anatomy. We report three adult patients with reversed intestinal rotation and review the embryology, clinical presentation and radiographic findings of this disorder. 장의 회전 이상(anomalies of intestinal rotation)은 대부분 신생아기에 발견되며 성인에서 발견되는 경우는 드물다. 장의 회전이상은 발생학에 근거를 두어 비회전, 역회전, 그리고 회전 이상으로 크게 세 가지로 분류를 할 수 있으며 이 중 역회전 이상이 가장 드물다. 역회전 이상은 특징적으로 횡행 결장이 상장간막동맥 혹은 십이지장보다 뒤쪽에 있게 된다. 따라서 영상학적으로 이러한 사실을 증명하면 진단할 수 있다. 저자들은 성인에서 발견된 3예의 역회전 이상을 경험하여 문헌 고찰과 함께 보고한다.
과혈관성 종괴로 오인된 간내 간문맥 낭상형 동맥류: 증례 보고
백현석,김재운,박원규,장재천 대한초음파의학회 2008 ULTRASONOGRAPHY Vol.27 No.1
A portal vein aneurysm is divided into two groups; an extrahepatic portal vein aneurysm and an intrahepatic portal vein aneurysm. The morphology of an aneurysm can be divided into types such as fusiform, bilobulated and saccular. A saccular aneurysm that arises from the intrahepatic portal branch is extremely rare. We report here a case of a saccular aneurysm of the intrahepatic portal branch mimicking an intrahepatic hypervascular mass, as seen on a dynamic CT scan, with the radiological findings. 간문맥 동맥류는 위치에 따라 크게 간외 및 간내 간문맥 동맥류로 나눌 수 있고 모양에 따라 방추형, 이소엽, 낭상형 등으로 분류된다. 그중 간내 간문맥에 발생한 낭상형의 동맥류는 매우 드물다. 저자들은 조영증강 전산화단층촬영에서 간내 과혈관성 종괴로 오인하였으나 색도플러 초음파에서 간내 간문맥에서 발생한 낭상형 동맥류로 진단할 수 있었던 1예를 경험하였기에 영상학적 소견과 함께 보고한다.

Background: The aim of this study was to establish the incidence, predictive factors, characteristics, and clinical outcomes of acute symptomatic seizures (ASS) after acute ischemic stroke (AIS). Methods: In total, 2,528 consecutive patients with first-ever AIS were included. Patients with a history of epilepsy or provoked seizures due to tumor, head trauma, brain surgery, or high fever were excluded. Onset seizure (OS) and ASS were defined as seizures occurring within 24 hours and 7 days after AIS, respectively. The incidence of ASS, type of seizures, presence of late unprovoked seizure (LUS), MRI, and electroencephalogram were analyzed. Results: ASS and OS occurred in 23 patients (0.9%) and 15 patients (0.6%), respectively; 20 of the patients with ASS (87.0%) had partial seizures and 4 (17.4%) developed status epilepticus. The incidence rates of ASS were 1.3%, 0.3%, and 0.2% in AIS caused by large-artery atherosclerosis, small-vessel occlusion, and cardioembolism, respectively. Of the 23 patients with ASS, the cortex was involved in 19 (82.6%), 16 patients (69.6%) had medium-sized to large lesions, the anterior circulation territory was involved in 21 patients (91.3%), and 4 patients (17.4%) developed MRI-confirmed hemorrhagic transformation of the lesions. Epileptiform discharges were observed in 9 (45%) of the 20 patients with ASS. Three of the 23 patients with ASS (13.0%) developed LUS. Conclusions: The incidence of ASS was 0.9% and was highest in the large-artery atherosclerosis group. The development of ASS was significantly associated with cortical involvement, medium-sized to large lesions, and lesions in the anterior circulation territory. Three of 23 patients (13%) developed LUS.
