# Incidental Finding of Ante-natal Fetal Neck Mass With Post-delivery Imaging and Follow-Up

## TL;DR

A fetal neck mass was accidentally found during prenatal screening and further examined after birth with imaging.

## Contribution

This case report highlights the incidental detection and follow-up of a fetal neck mass using post-delivery imaging.

## Key findings

- The fetal neck mass was incidentally detected during antenatal sonography.
- Post-delivery imaging confirmed the presence of the mass and provided further details.

## Abstract

Most fetal anomalies can be detected during the second trimester of chromosomal anomaly screening. However, even an experienced sonographer might fail to notice a fetal neck mass during this screening and would be diagnosed at a later point in time. In this case report, we have followed up on an incidentally detected case of fetal neck mass on antenatal sonography with post-delivery ultrasound and contrast-enhanced computed tomography.
