A Swedish woman woke up from surgery and found that instead of having her appendix removed, surgeons instead took one of her ovaries and a Fallopian tube, Sweeden’s The Local reported Tuesday.

Although the incident occurred in October 2007, the county hospital in Sundsvall-Harnosand in Sweeden is just now reporting it to the National Board of Health and Welfare.

The Vasternorrland County Council, which manages the hospital, said the surgery’s complex nature may have contributed to the mishap.
