[A neonate with a mass on the upper back].

Area of Science:

• Medical imaging
• Pediatric surgery
• Vascular anomalies

Background:

• Congenital vascular malformations present a diagnostic challenge in neonates.
• Early identification is crucial for appropriate management and to prevent complications.

Observation:

• A full-term newborn presented with a congenital skin-covered mass on the back.
• The mass exhibited a weak consistency upon physical examination.

Findings:

• Multicystic venolymphatic malformation diagnosed via ultrasound and magnetic resonance imaging (MRI).
• Imaging excluded spina bifida occulta, confirming the nature of the mass.

Implications:

• Treatment options include sclerotherapy or surgical excision for symptomatic cases.
• Asymptomatic venolymphatic malformations may be managed with a watchful waiting approach.
• This case highlights the importance of advanced imaging in diagnosing neonatal masses.
