11. When we decide if we should do a detailed investigation of a complaint, we look at whether there are signs the organisation has got something wrong. We do this by comparing what should have happened with what did happen. We have done this and have not found any indications that something has gone wrong.
12. Mrs H complains the Trust had failed to identify a problem from the scan taken on 23 March 2021.
13. The Trust say the radiologist reviewed the scans and confirmed the spinal canal soft tissue detected in the scan of 24 May could not be seen on the CT scan of 23 March. The Trust further stated ‘with the benefit of hindsight [Dr Z] wonders whether a component of chest wall pain was related to the now known about nerve root compression from the vertebral body disease at the T7 level. However, there were radiologically overt and progressive skeletal lesions (within the sixth rib) which clearly were a prima facie explanation for his symptoms’.
14. There are no specific clinical guidelines on how a scan should be reported. A scan is reported using the clinical details given. Our adviser explained a whole-body CT imaging should be reviewed as more than one plane (looking at scan from more than one direction to show different sections of the body). Soft tissue abnormalities should be assessed with soft tissue windows (used to view most organs). Dedicated lung windows (view lung parenchyma) should be assessed for lung metastases. The images need to be compared to previous imaging. It is best practice to assess the study on a dedicated radiology workstation at which the present and previous study can be linked to assess for any change.
15. Mr H had a whole-body CT scan on 23 March. The scan was compared to the previous CT scan on 19 August 2020. The images were viewed on soft tissue and bony windows in axial (top to bottom), coronal (front to back), and sagittal (side to side) planes.
16. Our adviser said on the left side at the level of T7 there is extensive metastases (cancer) from the pedicle (a stem or stalk of tissue that connects parts of the body to each other) towards the canal (spine) with subtle left sided epidural disease, but the canal appeared to have a lot of space with no suggestion of cord compression. In the absence of clinical history of symptoms, it would have been extremely difficult to identify the epidural thoracic disease from the 23 March scan.
17. CT imaging is less sensitive than an MRI in identification of tumour into the canal or cord compression. When Mr H was seen in hospital, it arranged for him to have an MRI. He complained of symptoms related to the area which made identification of the subtle abnormalities easier.
18. We recognise Mr H was in pain for several weeks after the scan taken on 23 March. Mrs H believes this pain could have been avoided had the radiologist read the scans correctly. We understand how upsetting it was to see Mr H in pain. Having considered the medical records and clinical advice, in the absence of specific symptoms related to T7, we would not have expected the radiologist at the Trust to identify the subtle epidural soft tissue from the CT scan done on 23 March. We therefore do not think the Trust missed the opportunity to do more.
19. We recognise how important Mrs H’s complaint is to her and thank her for bringing it to us to consider.
