What it is
Urachal cyst is a congenital urachal anomaly characterized by a failure of complete closure of the urachus, in which both ends are closed but the central lumen remains patent. It is typically asymptomatic but may become clinically significant when infected, presenting as a mass in the umbilical region accompanied by abdominal pain and fever.

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.
ICD-10 codes
ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.
