A 55-year-old female was admitted to the hospital presenting with a nodular shadow in the right lower lobe and marked elevation of serum CA19-9 levels. The patient was accidentally discovered with a high serum CA19-9 level of 494.39 U/ml (normal range, 0~37 U/ml) during a regular medical check-up. She had no obvious symptoms all the time, and the serum CA19-9 levels kept rising in the next tests.

Examination

A whole-body PET/CT scan revealed an old tuberculosis lesion at the right lower lobe. She was administered with one year of anti-tuberculous therapy (rifampicin + rimifon + ethambutol). At the same time, the shadow in the right lower lobe had no significant change, and the serum CA19-9 level increased to 1197.14 U/ml.
