After complaining of severe stomach cramps for a few days, the unnamed patient sought immediate medical advice – and was hospitalised.
Chinese doctors conducted various medical scans to understand what was causing her problem before they made the surprise discovery.
Filmed in Yiwu, Zheijang Province, they found that mushrooms as big as 7cm in diameter were living inside of her.
Due to being short on time while cooking, the 50-year-old did not wait for her dried shiitake mushrooms to expand in the water, local reports suggest.
Throwing them into her stew, she drank the mixture and swallowed several of the still-dehydrated organisms.
They are believed to have expanded inside her stomach, causing the painful blockage the next day.
