Can intussusception be seen on CT?
An ultrasound, X-ray or computerized tomography (CT) scan may reveal intestinal obstruction caused by intussusception. Imaging will typically show a “bull’s-eye,” representing the intestine coiled within the intestine. Abdominal imaging also can show if the intestine has been torn (perforated).
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.
Can intestinal TB be detected in CT scan?
Lesson 2: Radiological finding of abdominal TB is non-specific. Ultrasonography and computed tomography CT scan may show generalized or localized ascites with thin mobile septa, thick omentum and peritoneum, lymphadenopathy, or thickened bowel [4, 17,18,19].
What is the most likely radiographic appearance of intussusception?
There are findings that raise the concern for intussusception and would warrant further imaging. The most specific finding on radiography is a round, soft-tissue mass within the upper abdomen that can be seen in up to 60% of X-rays (Figure 1).
What is a lead point in intussusception?
The lead point of the intussusception is most often an enlarged lymph node (Peyers patch) in the terminal ileum. Occasionally, the lead point is an anatomic abnormality of the intestine (a “pathologic lead point”).
How is intussusception diagnosed in adults?
Given its rare prevalence and confusing clinical picture, the diagnosis of adult intussusception is a true challenge and can be missed without imaging studies. Currently, abdominal CT scan is the most effective imaging tool to detect intussusception, with a diagnostic accuracy ranging from 58 to 100% [21, 22].
What is the difference between intussusception and volvulus?
Intussusception refers to invagination or telescoping of a part of the intestine into itself, and malrotation volvulus is a congenital anomaly that results when the normal sequence of rotation and fixation of the bowel fails, which may result in intestinal obstruction.
How is ileocecal TB diagnosed?
The most common site of GI TB is the ileocecal region, if the area can be reached with a flexible endoscope. A rapid diagnosis can be achieved if smear or culture results are positive or if caseating granulomas are seen in biopsy samples.
How is TB peritonitis diagnosed?
Diagnosis is typically via ascitic fluid analysis with SAAG calculation, microbiological tests (mycobacterial culture growth), peritoneal biopsy, laparoscopy, or minilaparotomy.
What is intussusception radiology?
Intussusception occurs when one segment of bowel is pulled into itself or a neighboring loop of the bowel by peristalsis. It is an important cause of an acute abdomen in children and merits timely ultrasound examination and reduction to preclude significant sequelae including bowel necrosis.
Is intussusception seen on xray?
Intussusception may not be apparent on plain-film abdominal radiography. Radiographs may appear indeterminate or normal; therefore, the presence of an unremarkable abdominal radiograph should not be the basis for excluding a diagnosis of intussusception.
