The authors report a case of hepatic artery pseudoaneurysm diagnosed by abdominal computed topography in a 64-year-old woman who had undergone laparoscopic cholecystectomy the previous month. Definitive treatment was angiography with embolization. Key words: Hepatic artery pseuaneurysm, embolization

Castleman’s disease in the abdomen in children Clinical and sonographics findings: Case report and review of literature SUMMARY Castleman’s disease, also known as angiofollicular lymph node hyperplasia, is a rare benign disease, has two principal histologic types are hyaline-vascular and plasma cell types, can be unicentric or multicentric. The disease is usually detected by imaging diagnostic tools, but difficult to diagnose accurately before surgery and is easily confused with malignant disease. We present 5 cases of hyaline vascular unicentric Castleman disease in the abdomen, had been operated at Children's Hospital N01, we investigated the ultrasound characteristics and reviewed literature. Keywords : Castleman’s disease, ultrasound, in children

Mucinous cystadenocarcinoma appendix: a case report and review literature SUMMARY Background :Mucinous cystadenocarcinoma of the appendix is a rare disease. Detection situation is often presented with appendicitis symptoms. The appendectomy was underwent andthe result of mucinous cysadenocarcinoma appendix wasconfirmed onhistopathology. The patient is evaluated for staging to decide the next course of treatment. We report a case of mucinous cysadenocarcinoma appendix diagnosed and treated at Bach Mai Hospital and compared with the literature. Clinical case : A male patient, 65 years, admitted Bach Mai hospital because lower right quadrant. Patient was performed abdominal ultrasound and contrast enhanced computed tomography (CLVT) showed a 27mm appendix diameter, thickened around the perimeter of 7mm and lost the gastrointestinal tract, with little fluid around the appendix. Patients diagnosed before surgery: Appendicitis follow lymphoma. The patient underwent an appendectomy. Pathology results: Mucinous cystadenocarcinoma appendix. Conclusion :Mucinous cystadenocarcinoma appendix is a rare disease, clinical presentation and imaging is non-specific. Diagnosis mainly depends on pathology, then patient is evaluated to determine stage and decidednext course of treatment. Key word: Mucinous cystadenocarcinoma appendix.

Ectopic pancreas in the wall of intestine complicated with necrotic and inflamed intestine: A case report and review literature SUMMARY Background: Ectopic pancreas is a rare congenital condition characterized by pancreatic tissues located outside normal of confines of pancreas and lacking any anatomic or vascular connection with main pancreas. It can occur anywhere in the gastrointestinal tract but rarely are found in small intestine. Its preoperative diagnosis is difficult because the clinical symptoms are often nonspecific. We introduce a case of ectopic pancreas in the intestinal wall complicated with necrotic and inflamed intestine, which received a treatment by resection. Case presentation : A 44 years old man attended to Bach Mai hospital due to acute abdominal pain in epigastrium as result of gastrointestinal perforation. Contrast enhanced computed tomography (CT) of abdomen showed a mesenteric mass surrounded by inflamed fat in the left lower quadrant abdomen. In addition, CT images also suggested necrosis of the bowel wall next to the mass caused by twisting the mesentery and mesenteric vessels (whirlpool sign). The patient underwent local surgical resection and following histology revealed ectopic pancreatic tissues in the wall of intestine and necrosis of intestine. Conclusion : Although ectopic pancreas is rare, it should be considered in the differential diagnosis of a mesenteric or intestinal mass surrounded by necrotic and inflamed intestine. Keyword: Ectopic pancreas, mesenteric mass, intestinal mass, whirlpool sign.

Solid pseudopapillary tumor of the Pancreas SUMMARY Solid pseudopapillary tumors of the pancreas are rare in children. We present a 7-year-old girl with clinical presentation of intermittent abdominal pain after meal, no vomiting for 6 months. The abdominal ultrasound and computed tomography showed a mass that measuring 6,5x6,8x7 cm at the epigastric area. Total resection of the tumor were performed. The definite diagnosis was made by the post-operation pathological finding.

Pancreatic lymphôma – case report SUMMARY Pancreatic Lymphôma is most commonly a B-cell sub-type of non-Hodgkin lymphôma and is classified as either primary or secondary. We describe a case secondary Pancreatic lymphôma in a 64-year-old woman who presented with abdominal pain and weight loss for one month. Her laboratory tests upon admission were as follows : white blood cell count 9.6 G/l (reference range: 4,0-10,0), red blood cell 4.5 T/l (reference range: 3.8-5.8. The tumor marker levels of CEA; CA 125, CA 15-3, CA 19-9, αFP were all within the normal range. Abdominal ultrasound usually shows only a spenlic mass and many lymphô node in the abdomen. Gastroscopy and colonoscopy were normal. Abdominal multi slice computed tomography (MSCT) revealed a mass in the pancreatic body - tail and splenn suggest infarct lesions. There were many lymphadenopathies located at the portal hilus, para-aortic region and left renal hilus. PET/CT showed all lesions on the MSCT increased metabolic activity with maximal standardized uptake values (SUVmax) ranging from 8.9 to 17.0. Laparoscopy biopsy of pancreatic mass be performed to establish the diagnosis. In reports was extranodal marginal zone B cell lymphôma. The PET/CT after treatment 2 months suggest the disease respond well to treatment.

Case Report summa ry Appendiceal intussusception is not a common disease and is rarely diagnosed preoperatively. In our case, a 25-year-old male patient living in Ho Chi Minh City came to Medic Medical Center complaining about his epigastric abdominal pain, which lasting for 3 days. His body temperature was not high and he did not have any other symptoms. He recalled similar pain which had gone away without any treatment three months ago. Abdominal ultrasound showed abnormalities in appendix and cecum. During performing colonoscopy, we suspected appendiceal intussusception, and following computed tomography showed the images of enlarged appendix with fluid-filled lumen and signs of intussusception at the appendix base. The patient underwent an operation to remove the appendix and appendiceal intussusception was confirmed. Microscopic result was consistent with chronic appendicitis.

Double common bile duct: report of a case SUMMARY Double common bile duct is a rare congenital anomaly, charactered by two common bile ducts exist. One, named major common bile duct normally opens into the papilla duodeni major and the other named accessory common bile duct (ACBD) opens in different parts of upper gastrointestinal tract (stomach, duodenum, ductus pancreaticus. This anomaly is usually associated with some complications such as biliary inflammation, biliary lithiasis, choledochal cyst, anomalous pancreaticobiliary junction (APBJ), cholangiocarcinoma and upper gastrointestinal tract malignancies. We reported a 74 - year-old woman, presented with epigastric pain, chills, high fever and jaundice. Abdominal ultrasonography showed duplicated common bile duct and magnetic resonance imaging inlustrated double common bile duct type Va, classificated by Choi et al. The patient was diagnosed biliary infection without biliary lithiasis and cholangiocarcinoma, and treated with observal treatment and antibiotics. Keywords: Double common bile duct, Accessory common bile duct.
