Cervical bronchogenic cyst in a toddler.

Area of Science:

• Congenital abnormalities
• Pediatric surgery
• Head and neck imaging

Background:

• Bronchogenic cysts are rare congenital anomalies originating from the tracheobronchial tree.
• Their occurrence in the head and neck region is exceptionally uncommon.
• Differential diagnosis of pediatric neck masses often includes common entities like branchial cleft cysts.

Observation:

• A pediatric patient presented with a painless, enlarging right lateral neck mass.
• Initial clinical and MRI findings suggested a branchial cleft cyst.
• Histopathological examination revealed an incidental cervical bronchogenic cyst.

Findings:

• Cervical bronchogenic cysts are rare but important considerations in pediatric neck masses.
• Misdiagnosis is possible due to overlapping clinical presentations with other neck anomalies.
• Histopathology remains crucial for definitive diagnosis of rare congenital cysts.

Implications:

• Clinicians should include bronchogenic cysts in the differential diagnosis of pediatric lateral and midline neck masses.
• Advanced imaging like MRI may reveal incidental findings requiring further investigation.
• Awareness of rare presentations can improve diagnostic accuracy and patient management for congenital neck abnormalities.
