"MRI scan problem"

Husband attended Crosshouse hospital for MRI scan in January 2017 to investigate a fistula. In February, he presented to GP regarding testicular discomfort which has resulted in urgent referral for suspect cancer, and has now had surgery to remove the same. Mentioned recent MRI scan urology clinic appointment and when displayed on screen myself and my husband could clearly see the tumour, despite not being trained to read MRI scans. We are frustrated that this was not noticed on the initial scan, and the implications could have been very significant. Although the scan was not intended to look for this, we feel it should have been noted as an incidental finding. While the benefit to my husbands of raising this after it has happened may be minimal, we are keen that it results in lessons being learned.
