A recent report by the Health and Disability Commissioner highlighted the significant repercussions of two incidents where a sonographer and radiologist failed to detect critical issues in unborn babies, leading to enduring consequences for the families involved. These cases, occurring in 2021 and 2022, underscore the importance of precision and diligence in prenatal care.
In the first instance, the medical professionals overlooked signs of congenital pulmonary airway malformation (CPAM) during ultrasound scans, necessitating the complete removal of a baby’s lung post-birth. Had the condition been identified earlier, less invasive interventions could have preserved more of the child’s lung tissue, emphasizing the critical role of timely diagnosis in prenatal healthcare.
Furthermore, the second incident involved the failure to recognize renal agenesis in a twin pregnancy despite multiple ultrasounds, resulting in the tragic loss of one of the twins shortly after birth. Renal agenesis, characterized by the absence of one or both kidneys at birth, underscores the challenges and complexities involved in fetal anomaly detection during pregnancy.
The Health and Disability Commissioner’s investigation revealed lapses in image quality and adherence to guidelines by the sonographer, while the radiologist failed to identify crucial abnormalities, highlighting the need for stringent oversight and adherence to best practices in prenatal imaging.
Deputy Commissioner Rose Wall emphasized the responsibility of healthcare professionals to maintain high standards of clinical practice, stressing the pivotal role of ultrasound scans in identifying fetal developmental issues early on to mitigate risks and ensure optimal outcomes for both the mother and baby.

These incidents prompted referral of the sonographer and radiologist to medical regulatory bodies, underlining the gravity of the situation and the importance of upholding competency and professionalism in the healthcare sector. The delayed diagnoses had a profound impact on the families involved, underscoring the need for continuous improvement and vigilance in prenatal care.
Recognizing the need for systemic changes, the radiology service implemented training programs and scan audits to enhance the quality of care and prevent future oversights. The involved professionals also pursued further education to enhance their skills and knowledge, reflecting a commitment to ongoing professional development in the field of medical imaging.
Ultimately, these incidents serve as a stark reminder of the critical nature of prenatal screenings and the far-reaching consequences of missed diagnoses. By learning from these cases and implementing robust protocols, healthcare providers can strive to deliver optimal care and support expectant mothers in ensuring the health and well-being of their unborn children.
