Branched and polycystic thyroglossal duct anomaly

Area of Science:

• Medicine
• Pathology
• Surgery

Background:

• Thyroglossal duct cysts are common congenital anomalies of the neck.
• They typically present as midline cervical masses and rarely pose diagnostic challenges.
• Previous surgical attempts can complicate the presentation of these anomalies.

Observation:

• A young woman presented with a long-standing fistula, a complication of incomplete excision for a midline cervical mass.
• Imaging revealed an unusual thyroglossal duct anomaly characterized by a branched tract.
• The branched tract terminated in two distinct, separate cysts, indicating a polycystic presentation.

Findings:

• The case describes a rare branching and polycystic thyroglossal duct abnormality.
• This contrasts with the typical unilocular presentation of thyroglossal duct cysts.
• The patient's history of prior surgery complicated the clinical picture.

Implications:

• This case underscores the importance of considering rare anatomical variations in thyroglossal duct anomalies.
• It highlights the potential for complex presentations, including fistulas and polycystic structures.
• Accurate diagnosis and surgical planning are crucial for managing these unusual congenital abnormalities.
