Pneumatosis intestinalis (PI), defined as intestinal intra- and extramural gas accumulation, is a rare radiographic finding in conditions of intestinal wall damage of varied etiology. Here, we report on a 56-year-old female with multiple myeloma who presented with undulating fever, fluctuating abdominal symptoms, and a distended abdomen 5 months after allogeneic hematopoietic stem cell transplantation (HSCT). Abdominal X-ray and CT scan documented PI with gas accumulation both in the intestinal and colonic bowel walls...

INTRODUCTION: Anorexia Nervosa affects up to 1% of the population and can present with binge/purge episodes. A paucity of literature exists regarding small bowel and colonic ischaemia relating to this common condition. We report our own experience and management of a patient with anorexia nervosa binge/purge subtype with small bowel and colon ischaemia and review existing cases in the literature. PRESENTATION OF CASE: A 32year old female self-presented to the emergency department complaining of abdominal pain, abdominal distension and vomiting on a background history of binge/purge subtype eating disorder, following consumption of a large amount of carbohydrates...

Sclerosing mesenteritis is primarily diagnosed through histologic and radiologic evaluation; however, only a few works provide a systematic description using MRI. This work presents the case of a 68-year-old male, who was admitted for a routine cholecystectomy. Intraoperativly, a large mass was identified dislocating the abdominal viscera. The microscopic examination revealed vascular congestion of the omentum. The contrast-enhanced CT and MRI scans revealed the presence of a heterogenous, lipomatous mass with lesions visible only in T2W and contrast-enhanced T1W MRI...

The incidental detection of a tubulovillous adenoma at a contrast-enhanced computed tomography (CECT) with nondedicated protocol, performed in emergency conditions, is an uncommon finding. We report a case of a woman presenting with a subocclusive episode. A CECT scan was performed, and a pedunculated polyp could be appreciated at 3D-reconstruction images. A particular depiction of pedunculus of the polypoid lesion, resemble a clapper-bell, could help to define the vegetating lesion at the volume-rendering reconstruction images...

Primary colonic adenocarcinoma and synchronous rectal carcinoids are rare tumors. Whenever a synchronous tumor with a nonmetastatic carcinoid component is encountered, its prognosis is determined by the associate malignancy. The discovery of an asymptomatic gastrointestinal carcinoid during the operative treatment of another malignancy will usually only require resection without additional treatment and will have little effect on the prognosis of the individual. This article reports a synchronous rectal carcinoid in a patient with hepatic flexure adenocarcinoma...

Ampullary adenomas are a rare clinical entity, occurring at a rate of 0.04-0.12% in the general population. They are premalignant lesions which have the capability to progress to malignancy, and they should be excised if they are causing immediate symptoms and/or are likely to degenerate to carcinoma. Intestinal intussusception in adults is rare and, unlike in children, is often due to a structural pathology. Intussuscepting duodenal/ampullary adenomas have been reported in the literature on 13 previous occasions, however never before with this presentation...

Myelolipoma is a rare tumor composed of fat and bone marrow components, most of which are located in the adrenal gland. Myelolipoma in the liver is extremely rare. To date, only 10 cases have been reported in the English-language medical literature. In one of these cases, the hepatic myelolipoma was found within a hepatocellular carcinoma (HCC). In the present study, we report the first case of the synchronous occurrence of hepatic myelolipoma and HCCs in different liver sections of one patient, a 26-year-old female who was admitted to our hospital because of a 4-d history of upper abdominal pain...

Ileocolic intussusception due to Burkitt lymphoma is extremely rare in adults. A man aged 17 years presented with a history of recurrent abdominal pain over the past 3 weeks. The abdomen was distended with diffuse tenderness, and bowel sounds were present. Abdominal ultrasound and CT scans showed evidence of small bowel obstruction with marked wall thickening in the ileocecal region and 'target' signs suggestive for intussusception. At laparoscopy, a mass involving the caecum and the terminal ileum was found, along with multiple locoregional nodes, which was highly suggestive of malignancy...

A 31-year-old man presented with sudden right flank pain. We found a right renal tumor with a perirenal hematoma on enhanced abdominal computed tomography (CT), which suggested spontaneous rupture of the renal tumor. The tumor was located at the upper pole of the right kidney, and was not enhanced. Magnetic resonance imaging (MRI) showed slightly enhanced renal tumor, and positron emission tomography (PET) showed a hot spot in the renal mass. His anemia was getting worse, and we assumed that the renal mass was malignant...

A 45-year-old man with severe left flank pain was brought by ambulance to our hospital early in the morning. On arrival, his circulation dynamics were stable. His urinalysis results were normal, and ultrasonography showed no hydronephrosis. Abdominal dynamic computed tomography (CT) showed a huge retroperitoneal hematoma suspected of hemorrhage from a left adrenal artery aneurysm. After 3 hours of absolute bed rest, the patient experienced episodes of anemia, decreased blood pressure and increased pulse. Recheck of CT showed bleeding into the peritoneal cavity...

Adenosquamous carcinoma of the duodenal papilla is rare. A 73-year-old man was referred to the Saiseikai-Matsusaka General Hospital with upper abdominal pain and liver dysfunction. Computed tomography (CT) revealed dilatation of the common bile duct (CBD) and intrahepatic bile duct along with a tumor in the distal CBD. The tumor showed enhancement in the arterial phase on contrast-enhanced CT. We performed endoscopic retrograde cholangiopancreatography and noted a red, erosive, bleeding mass in the duodenal papilla with obstruction of the distal CBD, and dilatation of the CBD...

The association between vitamin D levels and nonalcoholic fatty liver disease (NAFLD) has been recognized. However, few studies showed independent associations between vitamin D deficiency and NAFLD after a sex-related adjustment for metabolic factors. We aimed to study whether vitamin D deficiency is an independent risk factor of NAFLD even after controlling for metabolic syndrome and visceral fat in both sexes. In this cross-sectional study, 7,514 Korean adults (5,278 men, 2,236 women) participated in a health check-up program...

OBJECTIVES: To determine the value of a raw data-based metal artifact reduction (SEMAR) algorithm for image quality improvement in abdominal CT for patients with small metal implants. METHODS: Fifty-eight patients with small metal implants (3-15 mm in size) who underwent treatment for hepatocellular carcinoma were imaged with CT. CT data were reconstructed by filtered back projection with and without SEMAR algorithm in axial and coronal planes. To evaluate metal artefact reduction, mean CT number (HU and SD) and artefact index (AI) values within the liver were calculated...

BACKGROUND: No consensus exists on management of children with a negative trauma CT following blunt abdominal trauma (BAT). Asymptomatic children are frequently "admitted for observation" following negative CT owing to concerns about missing an intraabdominal injury (IAI) without evidence for this practice. We aimed to investigate the feasibility of discharge following a negative CT scan in children sustaining blunt abdominal trauma. METHODS: Retrospective audit at a UK paediatric major trauma center and review of the literature...

A 50-year-old woman presented with epigastralgia. Computed tomography (CT) of the abdomen revealed a 6-cm well-enhanced mass extending from the left lobe of the liver to the abdominal wall, suggestive of cholangiocarcinoma. Liver and skin mass biopsies did not provide evidence of hepatic malignancy but were rich in plasma cells and sclerotic lesions. Subsequent detection of elevated serum immunoglobulin G4 (IgG4) led to a diagnosis IgG4-related inflammatory pseudotumor (IPT) of the liver. Treatment with systemic corticosteroids resulted in rapid clinical improvement...

PURPOSE: To use novel voxel-based 3D printed textured phantoms in order to compare low-contrast detectability between two reconstruction algorithms, FBP (filtered-backprojection) and SAFIRE (sinogram affirmed iterative reconstruction) and determine what impact background texture (i.e., anatomical noise) has on estimating the dose reduction potential of SAFIRE. METHODS: Liver volumes were segmented from 23 abdominal CT cases. The volumes were characterized in terms of texture features from gray-level co-occurrence and run-length matrices...
