Insights
Intra-abdominal foreign bodies can cause hip pain in children. Early diagnosis is crucial, as these cases highlight missed opportunities. Prompt identification and removal lead to complete symptom resolution.
Area of Science:
- Pediatric Surgery
- Pediatric Orthopedics
- Diagnostic Imaging
Background:
- Hip pain in children can stem from various causes, including infections and musculoskeletal issues.
- Intra-abdominal pathologies are often overlooked in the differential diagnosis of pediatric hip pain.
- Delayed diagnosis of intra-abdominal foreign bodies can lead to significant morbidity.
Purpose of the Study:
- To highlight the importance of considering intra-abdominal foreign bodies in pediatric patients presenting with hip pain.
- To emphasize the diagnostic challenges and missed opportunities in two pediatric cases.
- To underscore the need for a comprehensive evaluation in children with unexplained hip pain.
Main Methods:
- Case report of two pediatric patients presenting with hip pain.
- Initial orthopedic consultation for suspected infection.
- Magnetic Resonance Imaging (MRI) to identify intra-abdominal foreign bodies.
- Surgical removal of foreign bodies.
Main Results:
- Two boys, aged 8 months and 10 years, presented with hip pain.
- Intra-abdominal foreign bodies were identified via MRI after initial evaluations.
- Both patients underwent successful surgical removal of the foreign bodies.
- Complete resolution of hip pain and symptoms was achieved post-operatively.
Conclusions:
- Missed opportunities for early diagnosis of intra-abdominal foreign bodies occurred in both cases.
- Inadequate initial workup, including lack of specific imaging or physical examination, contributed to diagnostic delays.
- Abdominal foreign bodies should be a key consideration in the diagnostic workup of pediatric hip pain and limping.
Case:
Two boys, 8-months-old and 10-years-old, presented with hip pain. Orthopedics was consulted for possible infections, but intra-abdominal causes were not considered until after magnetic resonance imaging studies identified an intra-abdominal foreign body in each boy. Both patients underwent successful removal of the foreign bodies with complete symptom resolution.
Conclusion:
Both cases represent missed opportunities for early diagnosis of an intra-abdominal foreign body. In the first case, a lateral radiograph was not acquired. In the second case, the child's rectal pain after falling was not investigated with physical examination. Abdominal foreign bodies need to be considered when evaluating a child with hip pain/limping.

Purpose and Process:
Ultrasound I: Abdominal Ultrasonography
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...
