The lateral margin of the psoas muscle, contrasted by retroperitoneal fat, is usually visualized o plainabdominal radiography. Failure to visualize all or segment of lateral margin of the psoas muscle, so called psoassing, has been emphasized as reliable finding of retroperitoneal pathology. But the significance of psoas sign hasbeen controversial. The authors reevaluated ‘psoas sign’ by comparing 160 abdominal radiography with CT. Theresults were as follows: 1. In 160 supine radiographys, good visualization was present in 106 cases(66.3%), faintvisualizatin in 24(15.0%), segmental nonvisualization in 18(11.3%), and completer nonvisualization in 12(7.5%). In113 erect radiographs, good visualization was present in only 36 cases(31.9%). 2. Asymmetric visualization waspresent in 84 out of 160 cases. In patient with scoliosis, lateral margin of convex side was seen more clearlythan concave side, and this finding was statistically significant (p<0.005). 3. Ascites did not directly influenceto psoa visualization contrary to common belief. 4. In 54 cases of faint or nonvisualization, normal was16(29.6%), intraperitoneal pathology was 16(29.6%), and retroperitoneal pathology was 22(40.7%). 1) In normalpatient, psoas contact with kidney or intestine and deformed psoas muscle were responsible for poor visualization. 2) The major cause of poor visualization in intraperitoneal pathology were psoas contact with displaced kidney byhepatomegaly, ascites with scanty retroperitoneal fat and derformed psaos muscle. 3) The major cause of poorvisualization in retroperitoneal pathology were psoas invasion by tumor or inflammation, psoas conntact withenlarged kidney or perirenal lesion. 5. In summary, the mechanism of faint or nonvisualization of psoas marginwere: 1) psoas contact with normal or pathologic organs 2) psoas invasion by tumor or inflammation 3) deformedpsoas muscle 4) scanty retroperitoneal fat

In addition to imaging the lymphatics and detecting various types of lymphatic leakage, lymphangiography is a therapeutic option for patients with chylothorax, chylous ascites, and lymphatic fistula. Percutaneous thoracic duct embolization, transabdominal catheterization of the cisterna chyli or thoracic duct, and subsequent embolization of the thoracic duct is an alternative to surgical ligation of the thoracic duct. In this pictorial review, we present the detailed technique, clinical applications, and complications of lymphangiography and thoracic duct embolization.

BACKGROUND/AIMS: Ascites is a fairly common condition, but the clinical features of pseudomembranous colitis with ascites are not well-known. The aim of this study was to determine how the existence of ascites is related to the clinical factors. METHODS: Between March 2002 and June 2006, 67 pseudomembranous colits patients were diagnosed by performing lower endoscopy and biopsy. The patients' ascites was identified by abdominal plain radiography, ultrasonography or computerized tomography. The extension of colitis was evaluated by ultrasonography or computerized tomography. RESULTS: 16 patients (23.9%) had ascites. The serum WBC (p=0.01), hypoalbuminemia (p<0.01), CRP (p<0.01), recurrence (p<0.01), and extension of colitis (p<0.01) were associated with the existence of ascites. The four patients who had undergone paracentesis had a low SAAG level and PMN dominant ascites. CONCLUSIONS: There were correlations of ascities with leukocytosis, hypoalbuminemia, CRP, extension of colitis and recurrence of PMC.

OBJECTIVE: We wanted to evaluate the CT findings of epithelial origin ovarian carcinoma according to the degree of histologic differentiation. MATERIALS AND METHODS: This study enrolled 124 patients with 31 well differentiated, 44 moderately differentiated and 95 poorly differentiated carcinomas with epithelial origin. The CT images were retrospectively evaluated with regard to bilateral ovarian involvement, the tumor's nature, lymphadenopathy, adjacent organ invasion, peritoneal tumor seeding, a large amount of ascites and distant metastasis. In cystic, predominantly cystic and mixed tumors, the tumor wall, septa, papillary projection and necrosis in the solid portion were assessed. RESULTS: Bilateral ovarian involvement was more common in the poorly (48%) and moderately (42%) differentiated carcinomas than in the well differentiated carcinomas (7%) (p < 0.05). The frequency of a predominantly solid or solid nature was greater in the moderately and poorly differentiated carcinomas than in the well differentiated carcinomas (p < 0.0001). In the 87 tumors with a cystic, predominantly cystic or mixed nature, septa greater than 3 mm, papillary projection and necrosis in the solid portion were more common in the poorly differentiated carcinoma (91%, 91% and 77%, respectively) than in the moderately (64%, 68% and 34%, respectively) and well differentiated carcinomas (63%, 47% and 27%, respectively) (p < 0.05). Lymphadenopathy, organ invasion, tumor seeding and a large amount of ascites were more common in the poorly differentiated carcinomas (38%, 27%, 73% and 69%, respectively) than in the moderately (13%, 10%, 48% and 45%, respectively) and well differentiated carcinomas (3%, 0%, 10% and 17%, respectively) (p < 0.05). CONCLUSION: Epithelial origin ovarian carcinoma shows different CT findings according to the degree of histologic differentiation.

Eosinophilic enteritis is an uncommon disease that rarely manifests as an acute abdomen. A 50-year-old man visited our hospital and complained of epigastric and periumbilical pain. He reported direct and rebound tenderness over the periumbilical area. Laboratory examinations showed leukocytosis without eosinophilia. Plain abdominal radiography revealed air-fluid levels in the small intestine and computed tomography revealed concentric wall thickening in the small bowel and ascites in the pelvic cavity. We conducted an emergency operation and segmental resection of the jejunum was performed. Histologically, transmural, eosinophilic infiltration was observed. In patients with intestinal obstruction, even when presenting with an acute abdomen with no peripheral eosinophilia, eosinophilic enteritis should be included in the differential diagnosis.

Ovarin hyperstimulation syndrome (OHSS), an iatrogenic complication of ovarian stimulation, shows varying degrees of clinical manifestations. The pathogenesis of OHSS is an increase of vascular permeability resulting in hypovolemia, thromboembolism, ARDS, and death in sometimes. Pleural effusion is also a result of an increase of vascular permedability in the pleura. Thoracentesis is sometimes required to relieve dyspnea. We report a case of OHSS with bilateral exudative pleural effusfion is a 23 year-old female with resting dyspnea. She was received clomi;hen, FSH, and LH for the treatment of irregular menstruation twenty days previously. The ultrasonogram showed severe ascites and bilaterally huge ovary, and chest radiography showed bilateral effusion. Therapeutic thoracentesis and paracentesis were done for relief of the dyspnea. Two weeks later the bilateral effusion and symptoms disappeared spontaneously.

PURPOSE: To evaluate the radiographic findings of gastrointestinal anisakiasis with clinical and pathologic correlation. MATERIALS AND METHODS: In ten patients, findings were retrospectively analysed. There were two cases of the gastric variety of gastrointestinal anisakiasis and eight of the intestinal, and they were diagnosed during gastroscopy, by resection during surgery, and on the basis of typical clinical findings. All ten patients underwent both plain radiography and CT scanning of the abdomen. US was performed in five patients and an upper gastrointestinal series in one. Clinical data were evaluated with regard to a history of raw fish ingestion, time from ingestion of raw fish to onset of symptoms, location of abdominal pain, and laboratory data. Radiologic findings were analysed in terms of wall thickening and appearance, mesenteric infiltration, bowel dilatation proximal to lesion, and ascites. RESULTS: All patients had a history of recent ingestion of raw fish and complained of severe abdominal pain that occurred approximately 7-48 hours later. Pain occurred in the lower abdomen in five patients, the epigastrium in four, and the right lower abdomen in two. Laboratory test disclosed the leukocytosis in eight patients and eosinophilia in three. In all cases of intestinal anisakiasis, ileus was demonstrated on plain radiographs of the abdomen, while the upper gastrointestinal series showed mucosal thickening and multiple filling defects. US findings were bowel thickening and dilation, and on CT images, wall thickening revealed a target sign. Mesenteric infiltration and ascites were seen in seven patients. In four who underwent surgery, a cross-section through the lesion revealed submucosal eosinophilic granuloma with Anisakis larva. CONCLUSION: Although the CT findings are non-specific, taken in conjunction with characteristic clinical findings, they may be helpful in the diagnosis of gastrointestinal anisakiasis.

OBJECTIVE: We aimed to describe radiologic signs and time-course of imatinib-associated fluid retention (FR) in patients with gastrointestinal stromal tumor (GIST), and its implications for management. MATERIALS AND METHODS: In this Institutional Review Board-approved, retrospective study of 403 patients with GIST treated with imatinib, 15 patients with imaging findings of FR were identified by screening radiology reports, followed by manual confirmation. Subcutaneous edema, ascites, pleural effusion, and pericardial effusion were graded on a four-point scale on CT scans; total score was the sum of these four scores. RESULTS: The most common radiologic sign of FR was subcutaneous edema (15/15, 100%), followed by ascites (12/15, 80%), pleural effusion (11/15, 73%), and pericardial effusion (6/15, 40%) at the time of maximum FR. Two distinct types of FR were observed: 1) acute/progressive FR, characterized by acute aggravation of FR and rapid improvement after management, 2) intermittent/steady FR, characterized by occasional or persistent mild FR. Acute/progressive FR always occurred early after drug initiation/dose escalation (median 1.9 month, range 0.3-4.0 months), while intermittent/steady FR occurred at any time. Compared to intermittent/steady FR, acute/progressive FR was severe (median score, 5 vs. 2.5, p = 0.002), and often required drug-cessation/dose-reduction. CONCLUSION: Two distinct types (acute/progressive and intermittent/steady FR) of imatinib-associated FR are observed and each type requires different management.

This study aimed to assess and compare sarcopenia with other prognostic factors for predicting long-term mortality in cirrhotic patients with ascites. Clinical data of 65 among 89 patients with measurement of all parameters were consecutively collected. Sarcopenia was evaluated as right psoas muscle thickness measurement divided by height (PMTH) (mm/m). During a mean follow-up of 20 (range: 1-49) months, 19 (29.2%) of 65 patients died. The values of the area under the receiver operating characteristics curve (AUROC) of Child-Pugh score, Model for End-Stage Liver Disease (MELD) score, MELD-Na, and PMTH for predicting 1-yr mortality were 0.777 (95% CI, 0.635-0.883), 0.769 (95% CI, 0.627-0.877), 0.800 (95% CI, 0.661-0.900), and 0.833 (95% CI, 0.699-0.924), whereas hepatic venous pressure gradient was not significant (AUROC, 0.695; 95% CI. 0.547-0.818, P=0.053). The differences between PMTH and other prognostic variables were not significant (all P>0.05). The best cut-off value of PMTH to predict long-term mortality was 14 mm/m. The mortality rates at 1-yr and 2-yr with PMTH>14 mm/m vs. PMTH< or =14 mm/m were 2.6% and 15.2% vs. 41.6% and 66.8%, respectively (P<0.001). The mortality in cirrhotic patients with PMTH< or =14 mm/m was higher than those with PMTH>14 mm/m (HR, 5.398; 95% CI, 2.111-13.800, P<0.001). In conclusion, sarcopenia, evaluated by PMTH, is an independent useful predictor for long-term mortality in cirrhotic patients with ascites.

Therapeutic paracentesis is considered to be a relatively safe procedure and is performed commonly for the control of massive ascites in patients with liver cirrhosis. The commonest puncture site, approximately 4 or 5 cm medial of left anterior superior iliac spine, can be located across the route of the inferior epigastric artery, which is one of the sites of potential massive bleeding. In a 46-year-old woman with liver cirrhosis and refractory ascites, a huge abdominal wall hematoma developed after therapeutic paracentesis. The patient was not stabilized by conservative treatment, and inferior epigastric artery injury was confirmed on angiography. Angiographic coil embolization of the inferior epigastric artery was conducted, after which the bleeding ceased and the hematoma stopped growing. This case indicates that physicians performing paracentesis should be aware of the possibility of inferior epigastric artery injury and consider early angiographic coil embolization when a life-threatening abdominal wall hematoma develops.
