Assessment of the stomach is not commonly included in routine scanning protocol of upper abdominal ultrasound (USG). However, assessment of the stomach in patients presenting with epigastric pain can yield invaluable results. This paper presents, as an illustration, a case of carcinoma of stomach detected by transabdominal ultrasound. The diagnosis is ...
A perforated sigmoid colon cancer within an inguinal hernia is extremely rare. This unexpected finding is usually discovered during surgery and causes an unavoidable septic evolution. Here, we describe the case of an 84-year-old man who presented with fever, abdominal distension, and a painful, enlarged, left scrotum. A CT showed a left, incarcerated, ...

The imaging techniques used to follow-up patients submitted to surgery for colorectal cancers are presented as are their advantages and disadvantages. The sensitivity of ultrasonography (US) for postoperative surveillance of the liver varies considerably according to whether the absence or presence of metastases is sought (83%) or their exact number (53-82%). US is recommended by French clinicians ...
Modalities available for the diagnosis of blunt abdominal traumatic (BAT) injuries include focused abdominal sonography for trauma, diagnostic peritoneal lavage, and computed tomography (CT) of the abdomen/pelvis. Hollow viscous and/or mesenteric injury (HVI/MI) can still be challenging to diagnose. Specifically, there is debate as to ...
Traumatic injury of the superior mesenteric vein (SMV) by blunt trauma is a rare but frequently fatal injury. Although simple ligation should be considered for a patient in unstable condition, its complications have not been reported in detail. A 47-year-old man was struck on the abdomen during a fight. When he was transferred to a local hospital, he complained of severe ...

Thirty-three patients with carcinoma of the esophagus were studied. The computed tomographic ...
Patients with hepatitis C cirrhosis may sometimes have persistently elevated alpha feto protein (AFP) despite a lack of evidence for disease by ultrasound or computed tomography (CT). While this pattern may represent a benign manifestation of hepatitis C cirrhosis (HCC), it raises concern for the possibility of an occult hepatocellular carcinoma. It has previously been shown ...
Partial mesenteric ischemia is defined as an incomplete occlusion of the superior mesenteric artery resulting in acute abdominal pain, distended abdomen,and bowel hypomotility on auscultation. This disease can be acute or chronic and is caused by vascular occlusion or non-occlusive mechanisms. CT scan and ultrasound show a thickening ...

We discuss the case of a 75-year-old man who presented to the on-call urologists with a ...
A 74-year-old male claudicant who had a significant abdominal aortic stenosis was hydrated before aortic stent placement because of an elevated creatinine level. During the intervention the patient experienced acute abdominal pain with vomiting. No vascular cause was detected. Due to persistant pain, plain radiography and an abdominal ...
Over the past twenty years there has been a shift towards non-operative management (NOM) for haemodynamically stable patients with abdominal trauma. Embolisation can achieve haemostasis and salvage organs without the morbidity of surgery, and the development and refinement of embolisation techniques has widened the indications for NOM in the management of solid organ injury. ...
The rapid evolution in multidetector computed tomographic (CT) technology has produced improvements in temporal and spatial resolution, leading to greater recognition of the spectrum of abdominal findings in hereditary hemorrhagic telangiectasia (HHT).

A method is being developed to automatically extract liver ...
The American Joint Committee on Cancer (AJCC) staging of cutaneous melanoma is a continuously evolving system. The identification of increasingly more accurate prognostic factors has led to major changes in melanoma staging over the years, and the current system described in this review will likely be modified in the near future. Likewise, application of new imaging techniques has also changed the ...

In contrast to similar systems an additional ...
Presently, there are no guidelines to help predict which patients are more likely to have successful laparoscopic adhesiolysis. We attempt to define which preoperative characteristics of trauma patients who later develop small bowel obstruction are most amenable to a laparoscopic operation. We did a retrospective review of all patients with small bowel obstruction after previous laparotomy for ...
Concern over reported large radiation doses leading to a high cancer risk for paediatric CT patients has prompted considerable investigation in paediatric CT. The recent release of software from Germany has allowed effective doses to be calculated from CT protocol information and radiation measurement for standard paediatric patient ...

Splenic trauma in children following blunt abdominal injury is usually treated by nonoperative management (NOM). Splenectomy following abdominal trauma is rare in children. NOM is successful as in the majority of instances the injury to the spleen is contained within its capsule or a localised haematoma. Rarely, the spleen may suffer from an avulsion ...
The abdominal wall function of 57 patients who have undergone TRAM flap breast reconstructions using the whole rectus muscle, on one side (33 patients) or both (24 patients), was evaluated 6 months to 2 years after surgery. The defect was repaired with a Teflon mesh buried in the rectus sheath. There was a perfect tolerance to the mesh, and no hernia or bulging of the ...
Diaphragmatic hernias are characterized by defects in the diaphragm that allow herniation of abdominal contents into the thorax. Herniation through the retrosternal foramen of Morgagni is rare, with less than 300 adult cases reported in the literature. This is a case of a 90-year-old woman who was diagnosed with herniation of the liver through the foramen of Morgagni on F-18 ...
The liver is fixed in the right upper quadrant of the abdomen by a complex system of peritoneal reflections, known as ligaments. Embryologic evaluation shows that these ligaments, apparently unrelated, are part of a continuum: the ventral mesogastrium. The areolar tissue within the ligaments constitutes a potential space that links the liver with other viscera and with extraperitoneal sites, ...
X-rays computed tomographic (CT) scans of muscles of the lower limbs and the trunk in 14 patients with facioscapulohumeral muscular dystrophy (FSH) were studied. The CT scans showed that the affected muscles were decreased in density and size. The laterality of muscular involvement was sometimes observed. The ...
