Epiploic Appendagitis and Omental Infarction as Rare Causes of Acute Abdominal Pain in Children

Omental infarction diagnosed by computed tomography, missed with ultrasonography: A case report

BACKGROUND

Omental infarction (OI) is a surgical abdominal disease that is not common in adults and is very rare in children. Similar to various acute abdominal pain diseases including appendicitis, diagnosis was previously achieved by diagnostic laparotomy but more recently, ultrasonography or computed tomography (CT) examination has been used.

CASE SUMMARY

A 6-year-old healthy boy with no specific medical history visited the emergency room with right lower abdominal pain. He underwent abdominal ultrasonography by a radiologist to rule out acute appendicitis. He was discharged with no significant sonographic finding and symptom relief. However, the symptoms persisted for 2 more days and an outpatient visit was made. An outpatient abdominal CT was used to make a diagnosis of OI. After laparoscopic operation, his symptoms resolved.

CONCLUSION

In children’s acute abdominal pain, imaging studies should be performed for appendicitis and OI.

Epiploic appendagitis: Not so unusual cause of paediatric abdominal pain

Paediatric abdominal pain continues to pose a diagnostic challenge in the acute hospital care setting. We describe an eleven-year-old boy who presented to the emergency department with acute-onset, sharp abdominal pain localised to right lower quadrant. Abdominal imaging was diagnostic for epiploic appendagitis (EA), with pathognomonic 'ring sign' and 'central dot' visualised on the axial computed tomography images. He responded well to conservative treatment, including a short course of non-steroidal anti-inflammatory drugs. EA is a lesser-known paediatric entity mimicking surgical conditions. However, steady but sharp and non-migratory characteristic of the pain in either of the lower abdominal quadrants should raise suspicion for EA. Early accurate diagnosis can prevent unnecessary surgical exploration in these patients.

Omental Infarction in a Child-Conservative Management as an Effective and Safe Strategy in Diagnosis and Treatment

Omental infarction (OI) is a rare disease occurring in children. Important risk factors include overweight and obesity. The clinical presentation is often non-specific, and the main symptom is acute abdominal pain. In addition, infarcted omentum may present with fever, anorexia, nausea, vomiting, diarrhea and dysuria. Due to the localisation of the pain, OI should be differentiated from acute appendicitis. The diagnosis of OI is sometimes made intraoperatively, during appendectomy for suspected acute appendicitis. Hence, it is important to state a correct preoperative diagnosis, which is commonly based on abdominal ultrasound and computed tomography. The treatment of OI is still inconclusive. Both conservative and surgical treatments are used. Both methods have their advantages and disadvantages. The decision of which treatment to follow should be multifactorial and include the patient’s clinical condition at the time of admission, the progression or regression of symptoms during hospitalization and laboratory and imaging findings. We present a clinical case of a 9-year-old overweight girl with OI, whose diagnosis was based on imaging diagnostics and enabled conservative treatment with no complications. The case we have described confirms that the conservative treatment is an effective and safe therapy.
