Summary
Congenital epulis, a rare newborn oral mass, was diagnosed in a female infant. Imaging findings, including ultrasound and MRI, revealed specific characteristics suggesting this rare condition.
Area of Science:
- Neonatal pathology
- Medical imaging
- Oral surgery
Background:
- Congenital epulis is a rare, benign tumor of the gingiva that occurs in newborns.
- Early diagnosis and characterization are crucial for appropriate management.
- This case highlights the utility of advanced imaging in diagnosing rare neonatal conditions.
Observation:
- A newborn female presented with a significant oral mass (2.6 cm) identified postnatally.
- Antenatal ultrasound at 25 weeks was unremarkable.
- Postnatal ultrasound revealed a centrally hyperechoic, peripherally hypoechoic mass with branching vessels.
Findings:
- Magnetic Resonance Imaging (MRI) demonstrated a nonenhancing gingival mass.
- Specific MRI signal characteristics included an isointense rim on T1-weighted and low-intensity rim on T2-weighted sequences.
- MRI confirmed the gingival origin and absence of local extension, aiding in diagnosis.
Implications:
- The combination of clinical presentation and specific imaging features (branching vessels, peripheral rim on MRI) strongly suggests congenital epulis.
- Accurate prenatal and postnatal imaging can facilitate early diagnosis and surgical planning.
- This case contributes to the understanding of imaging findings for congenital epulis in neonates.
