Overview
In cystic fibrosis, ultrasound findings include small cystic degeneration could be observed in the tail of pancreas. Transabdominal ultrasound of the pancreas demonstrated a higher pancreatic echogenicity, as a measure of pancreatic lipomatosis in pancreatic insufficient CF patients. Echogenic bowel is found on ultrasound in 50% to 78% of fetuses affected with cystic fibrosis. It is thought to be caused by changes in the consistency of meconium in the small intestine as a result of abnormalities in pancreatic enzyme secretion. The sonographic findings include diffuse echogenic bowel, focal echogenic bowel with calcifications, hyperechoic mass and bowel dilation.
Ultrasound
In cystic fibrosis, ultrasound findings include:[1][2][3]
- Small cystic degenerations could be observed in the tail of pancreas (in younger patients).
- Transabdominal ultrasound of the pancreas demonstrated a higher pancreatic echogenicity, as a measure of pancreatic lipomatosis in pancreatic insufficient CF patients.
- Echogenic bowel is found on ultrasound in 50% to 78% of fetuses affected with cystic fibrosis. It is thought to be caused by changes in the consistency of meconium in the small intestine as a result of abnormalities in pancreatic enzyme secretion. The sonographic findings include:
- Diffuse echogenic bowel
- Focal echogenic bowel with calcifications
- Hyperechoic mass
- Bowel dilation
- Hyperechogenic bowel may be attributable to:
- Hypoperistalsis
- Decreased fluid content of the meconium
