Note the well-defined posterior acoustic shadow small arrows in relation to the appendicolith. Transverse ultrasound image of the mid- abdomen demonstrates multiple dilated, fluid-filled bowel loops B consistent with an ileus.
Small bowel obstruction could produce similar findings. Perforated appendicitis associated with shigellosis. Longitudinal pelvic sonogram through the right lower quadrant shows a multiloculated fluid collection FC.
One of the loculations contains debris D of low-level echogenicity. Transverse sonogram of the right lower quadrant shows free fluid arrows adjacent to bowel loops B.
Figure 3. Transverse pelvic US image at a lower level than Figure 2 shows an appendicolith large white arrow within the dilated appendix small black arrows.
Free fluid FF is noted anteriorly. Note posterior acoustic shadow S related to the appendicolith. Figure 4. Longitudinal US image of the mid-lower abdomen demonstrates the ventriculoperitoneal shunt tube arrows within free intraperitoneal fluid FF.
At surgery a perforated inflamed appendix with pus in the peritoneal cavity was found. Patient underwent appendectomy and externalization of the ventriculoperitoneal shunt. Appendicitis mimicking pelvic inflammatory disease. Conclusion Though ultrasound diagnosis of acute appendicitis is not as sensitive as CT scans, the lack of radiation exposure and potential earlier time to diagnosis and disposition suggest that it should be attempted prior to exposing patients to radiation.
Further practice by EPs will only improve diagnostic accuracy of acute appendicitis with bedside US and, as a result, improve the quality of patient care.

Prospective evaluation of emergency physician performed bedside ultrasound to detect acute appendicitis.
Eur J Emerg Med. Accuracy of ED sonography in the diagnosis of acute appendicitis. Am J Emerg Med. In sagittal plane, go far lateral with the probe until you are all the way out of the colon, and start scanning medially with gradual increase in pressure until you are out of the colon, and get into small bowel. A small, round, non peristalsing, bulls eye structure will appear lying over the iliopsoas muscle.
If not visualized, keep moving further up the colon scanning from lateral to medial with gradual increase in pressure. It is normal to see air in the appendix, also fecaliths have been noted in a normal appendix. If you see colon just as you turn on the iliopsoas muscle, there is a high probability the appendix is in the deep pelvis. White arrow points to cross sectional image, non peristalsing, fluid filled, bowel loop far lateral and superior to right ovary.
Procedure : The right lower quadrant is imaged in sagittal and transverse planes. Blockages can be the result of: stool foreign bodies objects or substances that have been introduced from the outside a tumor An early symptom of appendicitis is pain, often in the center of the abdomen but sometimes on the right side. Some individuals, particularly children, experience loss of appetite.
Several tests can be used to evaluate appendicitis: Abdominal or pelvic ultrasound may be performed. In young patients or women who are pregnant, MRI of the pelvis may be performed. MRI obtains pictures of the body using a strong magnet. Suspected Appendicitis-Child. Send us your feedback Did you find the information you were looking for?
