Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

The infantile polycystic kidney disease is rare fetal urinary tract anomaly. It is inherited with an autosomal recessive pattern and recurrence rate is 25%. The gene locus is on chromosome 6p. The pathogenesis of infantile polycystic kidney is the primary defect of the collecting ducts. The ultrasonographic finding of infantile polycystic kidney is oligohydramnios, bilaterally symmetrical enlarged kidneys with maintenance of their reinform shape. The differential diagnosis with adult polycystic kidney disease is important. The massive enlargement of the kidneys is rarely seen in adult polycystic kidney disease and the examination of the parents and other members of the family is helpful to confirm the adult polycystic kidney disease. If there is severe renal involvements, stillbirth or neonatal death secondary to pulmonary hypoplasia would be developed. If it were diagnosed before viability, termination of pregnancy is recommended. In a fetus at risk, diagnosed after viability, pregnancy termination is also recommended since this condition is uniformly fatal. We present a case of infantile polycystic kidney.

We examined the p53 protein overexpression and evaluated its correlation with pathobiological variables, including: (1) patient age, sex, tumor size, histological type and grade, invasion depth, vascular invasion, perineural invasion and lymph node status; (2) the Ki-67 labeling index in 100 gastric carcinomas; and (3) the DNA ploidy pattern, S phase fraction (SPF), and the proliferation index (PI) in 84 cases using flow cytometry. The positive rate of p53 staining was 48% and the p53 immunoreactivity was independent of variable clinicopathologic factors. No correlation was made between the Ki-67 labeling index with p53 immunostaining and DNA ploidy parameters. Aneuploidy rate was slightly higher in the p53 positive group (55.6%) than the p53 negative group (44.4%)(p=0.097). The mean values of SPF and PI were significantly higher in the p53 protein positive group. Aneuploidy was more often observed in the intestinal type (p=0.038), advanced gastric carcinoma (p=0.015) and lymph node positive group(p=0.039). The above results suggest that although the p53 protein overexpression has no significant correlation with pathological factors and the Ki-67 labeling index, it may play an important role in tumor cell proliferation. Since p53 protein overexpression was slightly higher in the aneuploidy group showing significant correlation with poor prognostic parameters, it is thought that re-evaluation of the p53 mutation by molecular biological study is needed.

BACKGROUND/AIMS: We compared the accuracy in the diagnosis of hepatic masses such as hepatocellular carcinoma (HCC), metastasis and hemangioma using enhancing pattern alone with using additional findings, and determined whether the additional findings could improve the diagnostic accuracy. METHODS/MATERIALS: Triphasic spiral CT images were retrospectively analyzed in 83 cases of hepatic lesions,' 40 HCC, 21 metastases, and 22 hemangiomas. Three observers made the diagnosis first by the enhancement pattern of the mass alone, and then, by the whole information. The diagnosis of a lesion was considered correct if the lesion was correctly categorized by at least two observers. Diagnostic accuracies of two sessions were compared with McNemar test. RESULTS: Using enhancing patterns alone, 31/40 HCC (78%), 8/21 metastases (38%), 21/22 hemangiomas (95%) were correctly diagnosed. The frequency of correct diagnosis was significantly improved when all images with additional findings were used: 36/40 (90%) HCC, 20/21 (95%) metastases, 22/22 (100%) hemangiomas (P=0.00006). Metastasis showed most prominent and statistically significant improvement in the diagnostic accuracy (P=0.0004). The number of correct diagnoses for HCC increased without statistical significance (P=0.17). However, the images with additional findings did not significantly contribute to the diagnosis of hemangiomas. The additional finidngs those led to correct diagnosis of metastases were multiple mass (7 cases), coexistence of primary malignancy (6 cases), and metastasis to other organ (1 case). The findings of liver cirrhosis were helpful to diagnose HCC correctly in 5 cases. CONCLUSION: The enhancing pattems of tumors were important in the diagnosis of hepatic masses in spiral CT. However, the additional finidngs were also helpful for the diagnosis of hepatic masses especially for the masses with atypical enhancement pattern. In metastases, the additional findings such as multiple masses or detection of primary malignant focus were useful to diagnose correctly.

CT has an important role in the evaluation of gastric adenocarcinoma. It clearly demonstrates the primary tumor itself and reveals the spread of cancer to adjacent or distant structures. It is therefore useful in the staging of gastric carcinoma, and has proved valuable in the differential diagnosis of this and other gastrictumors. Recent advances in technology such as spiral CT with water ingestion, improve the value of CT. This report describes the characteristic findings of gastric adenocarcinomas by spiral CT, and elucidates its role in the staging of gastric carcinoma.

Despite the remarkable developments in neurosurgical and neuro-interventional procedures, the optimal treatment for large or giant partially thrombosed aneurysms with a mass effect remains controversial. The authors report a case of a partially thrombosed aneurysm with a mass effect, which was successfully treated by stent-assisted coil embolization. A 41-year-old man presented with headache. Brain computed tomography depicted an 18x18 mm sized thrombosed aneurysm in the interpeducular cistern. More than 80% of the aneurysm volume was filled with thrombus and the canalized portion beyond its neck measured 6.8x5.6 mm by diagnostic cerebral angiography. Stent-assisted endovascular coiling was performed on the canalized sac and the aneurysm was completely obliterated. Furthermore, most of the thrombosed aneurysm disappeared in the interpeduncular cistern was clearly visualized follow-up brain magnetic resonance imaging conducted at 21 months. The authors report a case of selective coiling of a large, partially thrombosed basilar tip aneurysm.
