Midline posterior cervical cystic hygroma

Area of Science:

• Pediatric Surgery
• Congenital Malformations
• Head and Neck Surgery

Background:

• Cystic hygromas are common congenital neck masses with a known predilection for the left posterior triangle.
• These masses typically manifest early in infancy and childhood.
• While various locations are documented, midline presentations are exceptionally rare.

Observation:

• A case study involving a 9-month-old female infant presenting with a neck mass.
• The mass was identified as a cystic hygroma located in the posterior cervical midline.
• This specific location is unusual compared to typical cystic hygroma presentations.

Findings:

• The presented case is believed to be the first reported instance of a posterior cervical midline cystic hygroma.
• This finding expands the known anatomical variations for cystic hygroma occurrence.
• Diagnostic imaging and pathological examination confirmed the nature and location of the mass.

Implications:

• Highlights the importance of considering midline locations for congenital neck masses, even if rare.
• May prompt further investigation into the embryological factors contributing to midline cystic hygroma development.
• Informs surgical planning and management strategies for atypical cystic hygroma presentations.
