  • Appendicitis is a common disease in children. But left lower abdominal pain in acute appendicitis is a rare clinical feature. A 6 year-old-girl complained of left sided abdominal pain for 2 days. Past medical history was not contributory. Abdominal tenderness and guarding in left lower quadrant were noticed. Abdominal sonography and abdominal computed tomography scan demonstrated reversed position between superior mesenteric artery and vein, and a mass in the left lower quadrant abdomen suggesting appendicitis. Acute appendicitis in left lower quadrant, associated with intestinal malrotation, was found at laparatomy.

  • Gastric glomus tumor is a rare mesenchymal tumor that originates from modified smooth muscle cells of the glomus body. Glomus tumors are commonly observed in peripheral soft tissue, such as dennis or subungal region, but rarely in the gastrointestinal tract. A 39-year-old woman was admitted due to epigastric soreness. Upper gastrointestinal endoscopy revealed a subepithelial mass measuring 3.5 cm with central ulceration at the lesser curvature-posterior wall of the antrum. Characteristically, contrast enhanced abdominal computed tomography scan demonstrated high enhancement of the submucosal mass up to the same level of the abdominal aorta in the arterial phase; this enhancement persisted to delayed phase. Due to the risk of bleeding and malignancy, wedge resection of the submucosal tumor was performed. Histologic findings were compatible with a glomus tumor.

  • A 7-year-old, castrated, male Maltese dog presented with hyporexia and depression for 3 days. Elevated serum amylase, lipase activities, and liver enzyme values were found upon blood examination. An abdominal mass was seen on radiographs caudal to the gastric body in the left middle abdomen. In the left middle abdomen, abdominal ultrasonography also revealed a massive, irregularly marginated, heterogeneous mass of unknown origin, and in the right cranial abdomen, heterogeneously hypoechoic pancreatic tissue and hyperechoic change of adjacent mesenteric fat were observed. Contrast-enhanced computed tomography showed an irregular contour of the left pancreatic limb as well as heterogeneously enhanced parenchyma. A low-attenuating peripancreatic fluid collection with a thin and irregular wall was also seen. Based on these findings, an atypical pancreatic abscess with necrotizing pancreatitis which manifested as walled-off necrosis was suspected. The mass was excised, and the pancreatic abscess was confirmed by histopathologic examination. No complications were found in the patient after two months of follow-up examination.

  • Superior mesenteric artery (SMA) aneurysms are rare and often fatal. A 72-year-old man had previously been admitted to the emergency room with epigastric pain and heart murmur. The echocardiographic diagnosis was vegetation on the aortic and mitral valves, with moderate regurgitation from both valves due to infective endocarditis. No aneurysm was detected on abdominal computed tomography, and emergency double-valve replacement was performed. On postoperative day 25, the patient experienced abrupt abdominal pain, and computed tomography revealed a mycotic SMA aneurysm. Open surgical repair of the SMA aneurysm was performed using the femoral vein, and the patient's postoperative course was uneventful.

  • We report the case of a patient with gastric adenocarcinoma with multiple liver metastases. This patient showed complete remission for more than 68 months after S-1/cisplatin combination chemotherapy and radical total gastrectomy. The patient, a 63-year-old man, presented with dyspepsia and difficulty in swallowing. Endoscopic findings showed a huge ulcero-infiltrative mass at the lesser curvature of the mid-body, extending to the distal esophagus. Biopsy revealed a poorly differentiated tubular adenocarcinoma. An abdominal computed tomography scan demonstrated multiple hepatic metastases. S-1/cisplatin combination chemotherapy was initiated, and following completion of six cycles of chemotherapy, the gastric masses and hepatic metastatic lesions had disappeared on abdominal computed tomography. Radical total gastrectomy and D2 lymphadenectomy combined with splenectomy were performed. The patient underwent three cycles of S-1/cisplatin combination chemotherapy followed by tegafur-uracil therapy for 1 year. He remained in complete remission for more than 68 months after surgery.

  • Objective: Acute appendicitis is one of the most urgent surgical problems. Several factors have been considered as predictors of perforation, but this study focused on the change in pain pattern. The degree of pain and progression of appendicitis were analyzed assuming that the pain intensity would increase until the perforation and the degree of pain would decrease immediately after the perforation occurred. Methods: In this study, 385 out of 467 patients, who were diagnosed with appendicitis in a single institution and aged between 15 and 65 years, were reviewed retrospectively. The patients' pain scores and the diameters of appendices were analyzed along with the accompanying complications. Correlation analysis and a Student's t-test were performed. Results: In patients with complicated appendicitis, the mean numerical rating scale (NRS) was slightly higher than that of simple appendicitis, but there was no significant difference in the absolute value. Only the size of the appendix showed meaningful differences according to the combined computed tomography findings. The NRS distribution or appendiceal size did not correlate with the time duration from symptom onset. Conclusion: The appendiceal size tended to increase with progressing appendicitis. No significant correlation was observed between the patient's pain level and complications. The time duration from symptom onset did not show a relationship with the progression of appendicitis.

  • The purpose of this study was to predict abdominal obesity with 3-Dimensional computed tomography (3D CT) measurements of kidneys by analyzing the correlation between kidney sizes and abdominal obesity level. The subjects were 178 healthy adults without underlying diseases who had a comprehensive health examination at the Health Medical Center of Jesus Hospital in Jeonju. Abdominal obesity was measured by CT cross-sectional image at the level of the umbilicus and divided into visceral fat area, subcutaneous fat area, visceral fat/total fat ratio. The average comparison of kidney sizes classified according to abdominal obesity were performed through one-way analysis of variance (ANOVA) and Scheffe test. Pearson correlation analysis was performed to correlate all measurement values. The results of kidney size ANOVA analysis according to abdominal obesity were as follows. The means of kidney measurements according to visceral fat classification were significantly different in all kidney measurements (p<0.05). And in case of subcutaneous fat classification, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in the right kidney width (p<0.05). In case of visceral fat area/total fat area ratio, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in both kidneys width (p<0.05). Pearson correlation between kidneys measurements and CT abdominal obesity showed that visceral fat area had the highest correlation with the left kidney width measured by 3D CT (r=0.467) and subcutaneous fat area had correlation with the right kidney width measured by 3D CT (r=0.249). The visceral fat area/total fat area ratio had correlation with the left kidney width measured by 3D CT (r=0.291).

  • Purpose: Abdominal CT (computed tomography) is a principal diagnostic imaging modality for torso trauma at the Emergency Department (ED). When acute osseous pelvic injuries are detected by abdominal CT, additional three-dimensional (3D) reconstruction pelvic CT is often performed. We compared abdominal CT with pelvic CT to provide information about acute osseous pelvic injuries. Methods: A retrospective investigation of patients'electronic medical records during the five year period between January 1, 2004 and December 31, 2008 among Korean soldiers who underwent pelvic CT after abdominal CT at the ED was conducted. Axial images of abdominal CT were compared with axial images and 3D reconstruction images of pelvic CT. Results: Sixteen patients underwent subsequent pelvic CT after abdominal CT. Axial images of abdominal CT showed the same results in terms of fracture detection and classification when compared to axial images and 3D reconstruction images of pelvic CT. Pelvic CT (including 3D reconstruction images) followed by abdominal CT neither detected additional fracture nor changed the fracture type. Conclusion: This study has failed to show any superiority of pelvic CT (including 3D reconstruction images) over abdominal CT in detecting acute osseous pelvic injury. When 3D information is deemed be mandatory, 3D reconstructions of abdominal CT can be requested rather than obtaining an additional pelvic CT for 3D reconstruction.

  • An abdominal aortic aneurysm occurs most commonly in older individuals (between 65 and 75), and more in men and smokers. The most important complication of an abdominal aortic aneurysm is rupture, which is most often a fatal event. An abdominal aortic aneurysm weakens the walls of the blood vessel, leaving it vulnerable to bursting open, or rupturing, and spilling large amounts of blood into the abdominal cavity. surface modeling is very useful to surgery for quantitative analysis of abdominal aortic aneurysm. the 3D representation and surface modeling an abdominal aortic aneurysm structure taken from Multi Detector Computed Tomography. The construction of the 3D model is generally carried out by staking the contours obtained from 2D segmentation of each CT slice, so the quality of the 3D model strongly defends on the precision of segmentation process. In this work we present deformable model algorithm. deformable model is an energy-minimizing spline guided by external constraint force. External force which we call Gradient Vector Flow, is computed as a diffusion of a gradient vectors of gray level or binary edge map derived from the image. Finally, we have used snakes successfully for abdominal aortic aneurysm segmentation the performance of snake was visually and quantitatively validated by experts.

  • Rapunzel syndrome refers to a very rare condition in which swallowed hair forms a gastric trichobezoar that has a long tail extending into the small bowel. We describe a case of Rapunzel syndrome in an 8-year-old girl who presented with abdominal mass, epigastric pain and vomiting. Abdominal computed tomography scan showed a markedly dilated stomach filled with coarse heterogeneous materials. Upper gastrointestinal endoscopy revealed a huge hairy ball with a tail extending through the pylorus. We performed a surgical laparotomy and successfully removed a huge trichobezoar with a long tail extending into the middle portion of jejunum. Psychiatric consultation with review showed her past history of trichotillomania and trichophagia 4 years ago. But her parents denied further psychiatric therapy and she was lost to the follow-up. Rapunzel syndrome should be included in the differential diagnosis in children with chronic abdominal pain and trichophagia.
