Introduction: We describe a rare case of brachytherapy for prostate cancer in which a seed was lost from the perineum after a hydrogel injection. Case presentation: A 71‐year‐old Japanese man was diagnosed with localized high‐risk prostate cancer. Trimodality therapy with I‐125 brachytherapy was selected, and combined androgen blockade therapy was initiated. Brachytherapy and hydrogel injection were performed 7 months after combined androgen blockade initiation; 6 months later, the patient visited our hospital with complaints of redness and bleeding in the perineum. Serous effusion and loss of a seed on the right side of the perineal anus were observed. Pelvic magnetic resonance imaging showed a tunnel like discharge of hydrogel from the dorsal prostate to the perineum. The fistula was incised, the seed was removed, and drainage was performed. Conclusion: Appropriate diagnosis and treatment with careful follow‐up are required in patients at high risk of infection after brachytherapy with hydrogel injection.
