Can you see intussusception on CT scan?
In most cases, radiologists can readily make the correct diagnosis of intestinal intussusception by noting the typical bowel-within-bowel appearance at abdominal CT. However, the CT findings that help differentiate between lead point and non–lead point intussusception have not been well studied.
What are the physical findings in intussusception?
The hallmark physical findings in intussusception are a right hypochondrium sausage-shaped mass and emptiness in the right lower quadrant (Dance sign). This mass is hard to detect and is best palpated between spasms of colic, when the infant is quiet. Abdominal distention frequently is found if obstruction is complete.
What is the classic triad for intussusception?
The triad of symptoms, including paroxysmal pain, vomiting, and bloody stool, is described in textbooks as the classic triad of intussusception, but several previous studies have reported these symptoms in only 10 to 20% of cases (2, 16, 19).
What is sausage shaped mass?
Further, a red, mucus or jelly-like stool is usually seen with intussusception. Physical examination may reveal a “sausage-shaped” mass felt upon palpation of the abdomen. Symptoms of intussusception may resemble other conditions or medical problems.
Which of the following is the triad of symptoms often seen with intussusception?
The classic triad of intussusception include crampy (intermittent, also known as colicky) abdominal pain, vomiting, and bloody stools. The classic triad was found in only 21% of cases and two symptoms were found in 70% of cases in one series of patients with intussusception (1).
What is currant jelly stool a clinical manifestation of?
Other frequent signs and symptoms of intussusception include: Stool mixed with blood and mucus — sometimes referred to as currant jelly stool because of its appearance. Vomiting. A lump in the abdomen.
What is intussusception complications?
Without treatment, intussusception can lead to life-threatening complications, such as. intestinal obstruction. dehydration link. lack of blood flow to the blocked part of the intestine and death of the blood-starved tissues. a perforation, or hole, in the wall of the intestine.
What does intussusception look like on xray?
To summarize, the radiographic signs of intussusception are: 1) target sign, 2) crescent sign, 3) absent liver edge sign (also called absence of the subhepatic angle), and 4) a bowel obstruction. Recall that the target sign is a mass in the right upper quadrant.
What are the diagnostic clues of chronic pulmonary thromboembolism?
A helpful diagnostic clue in most cases of chronic pulmonary thromboembolism is the presence of multiple bilateral arterial abnormalities. Occlusion of one main pulmonary artery, mimicking proximal interruption, is rarely seen and has been reported in only 3% of cases (, 55 ).
Which CT findings are characteristic of idiopathic pulmonary arterial hypertension (IPA)?
Characteristic vascular features of idiopathic pulmonary arterial hypertension depicted at CT are central pulmonary artery dilatation, usually in the absence of detectable intraluminal thrombi; small tortuous peripheral vessels representing plexogenic arteriopathy; and an abrupt decrease in the caliber of segmental and subsegmental arteries.
Which CT findings are characteristic of pulmonary arteriovenous shunt?
Other frequent CT findings include small, rounded parenchymal opacities in the lung periphery with a dilated, tortuous feeding artery and an enlarged draining vein, features that represent CT-detectable macroscopic arteriovenous shunts ( 5 ).
Which CT findings are characteristic of pulmonary venous hypertension (VPH)?
CT scans in patients with pulmonary venous hypertension show pulmonary interstitial and alveolar edema with signs of pulmonary arterial hypertension. High-resolution CT with standard axial and angiographic acquisitions is useful for identifying underlying disorders and differentiating among the various causes of secondary pulmonary hypertension.
