The relationship between the growth of fetal abdominal circumference and the fetal age was determined by ultrasonography during the 28-41 weeks of gestation in 123 normal pregnancy. A closed correlation was identified and an equation was established

Leiomyomas of the appendix are rare and most are encountered incidentally during exploration of the abdomen for some other disease, during postmortem examination, or in the course of routine pathologic examinations of surgical specimens. We report here the findings of ultrasonography, CT and surgery of a case of leiomyoma that arose from the appendix; this lesion was pathologically confirmed.

Gastric schwannoma is a rare benign intramural tumor arising from the stomach, and it accounts for only 0.1% of all the different kinds of gastric neoplasms, and it's less than 4% of all the benign gastric tumors. This tumor is very difficult to differentiate from the other mesenchymal tumors by the clinical, endoscopic and radiologic findings. In this study, we demonstrate the appearance of this tumor on endoscopic ultrasound and contrast-enhanced abdomen CT. We also show the histopathologic findings of a surgically confirmed gastric schwannoma that was located in the proper muscle layer.

We report a case of pancreatic pseudocyst presenting as an intramural gastric tumor on upper gastrointestinal examination, endoscopic ultrasound and computed tomography of the abdomen. Pancreatic pseudocysts in the stomach wall is rare and the most of them presented as a cystic mass, but this case was presented as a gastric mural solid tumor. Exploration revealed an about 4 4 2 cm sized round mass at the midbody of great curvature of stomach, it was in the muscle layer, and removed by surgical operation. The correct diagnosis of this case was established postoperately on the pathologic examination revealed pancreatic pseudocyst.

PURPOSE: The correlation between sonographic findings and clinical symptoms was investigated in the patients with mesenteric lymphadenitis who had recurrent acute abdomen. MATERIALS AND METHODS: Seventy-eight children with recurrent acute abdominal pain without obvious primary disease were evaluated by sonography. The initial and follow-up sonography were performed in 17 children. The abdomen was divided into 3 areas. The number and size of mesenteric lymph nodes were observed in each zone, and was compared with the clinical findings. RESULTS: In 56(71.8%) of 78 cases, good correlation was seen in the area of the greatest size and number of the lymph nodes in the sonography. Most severe symptom, was seen in the right lumbar area(49 cases) and umbilical area(7 cases). In 17 cases of follow up, 14 cases showed decrease size and number of mesenteric lymph nodes while 2 cases showed increase in size and number of the nodes with aggravated symptoms. CONCLUSIONS: Ultrasonography was useful to detect and localize the enlarged mesenteric lymph nodes. Initial and follow-up sonography showed good correlation between the changes in number and size of the lymph nodes and symptoms.

Fetus in fetu is a very rare congenital abnormality in which one vertebrate fetus is enclosed within the abdomen of another fetus. With advancing ultrasound imaging technique, a few case of prenatal diagnosis is reported recently. A case of fetus in fetu with 6 X 6 X 4 cm sized cystic mass in the fetal retroperitoneum was diagnosed prenatally using ultrasound and confirmed by ultrasound and computer tomogram after delivery. This mass was removed completely from delivered baby and finally confirmed fetus in fetu by pathologic examination. Solid portion in this mass was composed of vertebral organization with limb bud, well-developed organ system.

Primary hepatic leiomyosarcoma is an extremely rare neoplasm, with fewer than 60 previously reported cases. Apatient was admitted with pain and palpable mass in the right upper abdomen. An ultrasonogram showed a largecystic mass with irregular thick wall in the right lobe of the liver. On a CT scan, the mass showed irregular enhancement along its wall, but central portion was not enhanced. A celiac angiogram revealed a large hypervascular mass with abundant abnormal vascularities in its peripheral portion. Right hepatectomy was undertaken, and histologic examination, revealed hepatic leiomyosarcoma.

Perforated appendicitis with an abscess formation is known to be the most common cause of tender mass in right lower abdomen. The differential diagnosis of a tender mass in right lower abdomen, however, is broad and includesvarious intraabdominal and intrapelvic lesions in origin. Preoperative accurate diagnosis is essential in order toavoid unnecessary surgery or complications resulting from delayed surgery. The purpose of this pictorial essay isto illustrate examples of various causes and methods to differentiate them with ultrasonography and CT.

An inflammation of an epiploic appendage is a relatively rare cause of acute abdominal pain. It can be clinically misdiagnosed as either acute appendicitis or diverticulitis. Judicious interpretation of imaging with ultrasound or computed tomography may lead to an early diagnosis and prevent unnecessary surgical or medical treatment. Conservative treatment of symptoms is usually sufficient. We have experienced a case of epiploic appendagitis treated by conservative management and report this case with the review of the literature.

Cholangiocarcinomas have several histologic types, but intrahepatic cholangiocarcinoma with sarcomatous change is rare. A 71-year-old man was admitted to our hospital because of fever which had lasted two months. Ultrasonography (US) of the upper abdomen demonstrated a huge hepatic mass with central solid and peripheral cystic portions, and computed tomography (CT) revealed a heterogeneous hepatic mass with a central area in which enhancedment was delayed. Magnetic resonance imaging (MRI) disclosed a huge mass of predominantly low signal intensity at T1WI, and peripheral portions of high signal intensity and a central portion of intermediate signal intensity at T2WI. The pathologic diagnosis was cholangiocarcinoma with sarcomatous change.
