Introduction. Femoral hernia in children is very rare and it appears in 0.2% of all hernias during childhood. It is three times more frequent in girls. The aim of this paper is to present a female infant with incarcerated femoral hernia. Case outline. A female infant aged three months was hospitalized with classical clinical signs of incarcerated left femoral hernia. After preoperative preparation, a transversal inguinal incision was performed on the left side and an incarcerated femoral hernia was confirmed with a torn and gangrenous left ovary and fallopian tube. Following adnexectomy, the hernia sac was ligated and resected and hernioplasty was made by the reconstruction of the Cooper?s ligament. Conclusion. A delayed surgical intervention for incarcerated femoral hernia in a female can result in a loss of the ovary and the fallopian tube, which may lead to serious consequences later in life.
