Littre’s umbilical hernia (UH) is a rare disease, the third most common Littre hernia. Most case reports interest adult patients. We reported the case of a four-year-old girl with anemia and symptomatic UH, with an incidentally diagnosed Meckel’s diverticulum (MD) containing pancreatic ectopic tissue. We reviewed case reports on Littre’s umbilical hernia without a date or language restriction. Including our patient, 21 cases were reviewed, of whom 15 (71.4%) were adults and 13 (61.9%) were males. Complicated umbilical hernia occurred in 13 patients (61.9%) and symptomatic MD in two children (9.5%). Investigations preoperatively diagnosed two patients (9.5%). Eighteen patients (85.7%) underwent open surgery, Meckel’s diverticulum removal was performed in 18 patients (85.7%), and primary umbilical hernia repair was performed in 16 (76.2%). Ectopic tissue was present in four patients (19.1%), and long-term outcomes were excellent in all patients.
