Insights
Sigmoid fecal impactions can mimic retroperitoneal neoplasms in children, causing lateral ureteral displacement. This diagnosis should be considered to avoid unnecessary imaging or surgery.
Area of Science:
- Pediatric Radiology
- Pediatric Gastroenterology
- Pediatric Surgery
Background:
- Abdominal masses in children can present diagnostic challenges.
- Retroperitoneal neoplasms are a concern in pediatric abdominal imaging.
- Ureteral displacement can indicate underlying pathology.
Observation:
- Two pediatric cases presented with curvilinear lateral ureteral displacement.
- The identified abdominal masses were diagnosed as sigmoid fecal impactions.
- This finding mimicked signs of retroperitoneal neoplasm.
Findings:
- Sigmoid fecal impaction is a potential cause of lateral ureteral displacement in children.
- Fecal impaction can radiographically resemble retroperitoneal masses.
- Accurate diagnosis is crucial to guide appropriate management.
Implications:
- Consider fecal impaction in the differential diagnosis of pediatric abdominal masses with ureteral displacement.
- Avoidance of potentially unnecessary radiographic or surgical interventions.
- Highlights the importance of clinical correlation in pediatric imaging interpretation.
Abstract:
Two cases of curvilinear lateral ureteral displacement in children with abdominal masses are reported. The masses proved to be sigmoid fecal impactions. This possibility must be considered before embarking on radiographic or surgical evaluation of possible retroperitoneal neoplasm.
