Hidden metastatic lung tumour diagnosed by AI

A 75-year-old woman who attended for a routine x-ray appointment was given the all-clear after the image was reported as having no atypical findings (figure). The investigation had been arranged as part of the follow-up package for the patient who, 3 years earlier, had an abdominoperineal resection for rectal and anal cancer. The rectal carcinoma was a moderately to well differentiated tubular adenocarcinoma, 25 mm × 20 mm, pT2N0M0 stage I; the anal carcinoma was a squamous cell carcinoma, 5 mm × 5 mm, pTisN0M0 stage 0.
