RÉSUMÉ

BACKGROUND/AIMS: The aim of this study was to evaluate the diagnostic accuracy of 64-multidetector CT (MDCT) cholangiography for determining the causes of distal common bile duct (CBD) obstruction. METHODS: Two hundred fifty consecutive patients underwent 64-MDCT for diagnosing the clinical and biochemical signs of bile duct obstruction. The causes of bile duct obstruction were assessed by the pre- and post-enhanced axial and coronal multiplanar reformation images of 64-MDCT. The results were compared with ERCP, biopsy and surgery. RESULTS: The sensitivity and specificity of MDCT for CBD stones were 96.1% and 84.9%, respectively. In seven patients, The CBD stones in 7 patients could not be detected on MDCT. Eleven patients with stones in the distal CBD, as detected on MDCT, had no stones seen on ERCP. For malignant obstruction, the sensitivity and specificity of MDCT were 97.0% and 98.6%, respectively. Three patients who were diagnosed with periampullary cancers on MDCT were disclosed to have severe papillitis on ERCP. One patient who was diagnosed with CBD stone by MDCT was disclosed to have ampullary cancer. The overall accuracy of MDCT for determining the causes of biliary obstruction was 90.5%. CONCLUSIONS: MDCT cholangiography is a non-invasive method with relatively high sensitivity and high specificity for diagnosing the causes of distal CBD obstruction.

RÉSUMÉ

BACKGROUND/AIMS: The multidetector computed tomography (MDCT) scanning frequently leads to the incidental discovery of bowel wall thickening. The aim of this study was to determine the utility of gastroscopy and colonoscopy in the management of patients who had incidental discovery of bowel wall thickening on MDCT. METHODS: From May 2006 to March 2008, the abdominal MDCT reports of all patients in Chungbuk National University Hospital were reviewed. Cases with any bowel thickening was selected and then patients who received gastroscopy or colonoscopy after abdominal MDCT were re-selected. RESULTS: Gastroscopy revealed abnormal findings in 22 (95.7%) out of 23 patients, and 10 patients (43.5%) had stomach cancers. Colonoscopy revealed abnormal findings in 35 (85.4%) out of 41 patients, and 12 patients (29%) had malignant tumors. In the patients who had lymph node enlargement (p<0.001), dirty fat infiltration (p=0.025), and irregular wall thickening (p<0.001) on MDCT malignancy was observed more frequently. CONCLUSIONS: We recommend gastroscopy and colonoscopy to patients who had incidentally found bowel wall thickening on MDCT, especially those with lymph node enlargement, dirty fat infiltration, and irregular wall thickening.

RÉSUMÉ

Hidradenitis suppurativa is a rare disorder that is characterized by recurrent chronic skin infections and the formation of sinus tracts and considerable scaring. A 37-year-old man presented with a hard posterior neck mass. Multiple pus-producing sinuses were detected in the skin covering the mass. MRI demonstrated an ill-defined, soft tissue mass with multiple variable sized cystic lesions. The soft tissue mass measured 12x10x4 cm in the subcutaneous fat layer, it contained multifocal cystic lesions that revealed higher signal intensity on both the T1- and T2-weighted images, as compared with the adjacent neck muscles. The mass was not enhanced on the post-contrast T1 weighted images. Some of the cystic lesions extended to the skin. The mass was removed surgically and confirmed to be hidradenitis suppurativa.

RÉSUMÉ

Cardiac tamponade with pleural and pericardial effusion is a rare but life-threatening complication of umbilical venous catheterization in the newborn. It requires a timely diagnosis and urgent treatment, such as pericardiocentesis, to save lives of affected patients. Recently, we experienced a 7 day-old, very low birth weight infant, who developed a cardiac tamponade with pleural and pericardial effusions complicated by umbilical venous catheterization. The patient was successfully treated with pleural and pericardial drainages. Here, we report this case with a review of literature, since there has been no such previous case reported in Korea.

RÉSUMÉ

Congenital lobar emphysema (CLE) is an overinflation of infantile pulmonary lobe caused by air trapping within the affected area. This is usually diagnosed on radiological findings postnatally. Most cases present in the neonatal period with signs of acute or chronic respiratory distress. There are only a few reports of CLE in the literature with prenatal sonographic feature documented. The routine use of prenatal sonography has helped to find fetal anomalies, such as fetal lung mass, that pose a challenge to early diagnosis, appropriate counselling, postnatal follow-up, and better outcome. A boy with CLE was detected by prenatal sonogram. He had a uniformly echogenic right lung with mediastinal shift to the left which was suspected type III congenital cystic adenomatoid malformation prenatally. He showed no evidence of respiratory distress at birth, but experienced progressive tachypnea and chest retraction. He had right middle lobectomy on the seventh postnatal day and pathologic diagnosis of CLE had been made. We report this rare case with brief review of literature. This is the first domestic case which was detected prenatally and confirmed pathologically after lobectomy.

RÉSUMÉ

Hemophagocytic lymphohistiocytosis(HLH) is a rare and fatal disorder in children. Persistent fever, hepatosplenomegaly and pancytopenia are observed in the most cases with the characteristic change of serum triglyceride, fibrinogen, ferritin and LDH level. CNS manifestation were developed in 50-70% of HLH. 20% of cases revealed seizure and irritability at diagnosis. Abnormalities on brain imaging, such as diffuse white matter abnormalities and necrotic area with parenchymal volume loss appeared to roughly parallel the severity of clinical manifestations. In HLH, EBV is the major triggering agent inducing hemophagocytosis as well as the fulminant course of disease. Many cases of EBV-HLH had monoclonal origin and respond well to etoposide-containing regimens. Early induction of an etoposide based regimen is critical factor in securing long-term survival in patients with EBV-HLH. We report a case that 13 year-old female patient with seizure and loss of consciousness was diagnosed as EBV-HLH and treated with protocol HLH-94 consistd of etoposide, dexamethasone, cyclosporin.
