Insights
Solitary intestinal fibromatosis (SIF) is a rare condition in infants. This case highlights unusual antenatal findings and successful surgical outcomes for this rare intestinal tumor.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Developmental Biology
Background:
- Solitary intestinal fibromatosis (SIF) is an exceptionally rare mesenchymal tumor affecting the gastrointestinal tract.
- Limited case reports exist, particularly in neonates and infants, underscoring the rarity of this condition.
Observation:
- This report details a novel case of SIF presenting with atypical antenatal echographic findings.
- The diagnosis was confirmed in a 2-month-old infant experiencing intestinal obstruction.
Findings:
- SIF is a rare cause of intestinal obstruction in infants.
- Complete surgical excision is curative for SIF, leading to an excellent prognosis.
Implications:
- Early recognition of SIF, even with unusual antenatal signs, is crucial for timely intervention.
- This case contributes to the limited literature on SIF, aiding in understanding its presentation and management in early life.
Abstract:
Solitary intestinal fibromatosis (SIF) is rare. Only 16 cases have been described in the new-born and infancy. We describe a new case of SIF with an unusual presentation including abnormal antenatal echographic findings. SIF was diagnosed at 2 months age when the child developed an intestinal obstruction. Differential diagnosis and review of literature are discussed. This lesion has an excellent prognosis when it is completely excised.
