urachal cyst


Also found in: Wikipedia.

urachal cyst

a cystic remnant in the urachus derived from the intraembryonic part of the allantois.

urachal cyst

A cyst that develops in the urachal sinus between the obliterated cephalad end of the urachus at the umbilicus and caudal end at the bladder dome. They are rarely symptomatic during infancy but are found incidentally in early childhood or adolescence during bladder ultrasonography for other reasons (e.g., urinary tract infections).
 
Clinical findings
Often related to infection (most often due to Staphylococcus aureus) and inflammation (suprapubic mass, fever, pain, voiding symptoms), and rarely death due to intra-abdominal rupture.

urachal

pertaining to urachus.

urachal abscess
a mass palpable in the abdomen dorsal to the umbilicus to which it is usually connected by a fistula that drips pus continually.
urachal cyst
symptomless fluid-filled cavities in the urachal ligament.
urachal diverticulum
visible with contrast radiography as an extension of the bladder at the vertex. See also vesicourachal diverticulum.
urachal inflammation
usually results from an extensive infection of the umbilicus. The urachus may or may not be pervious. Cystitis or urachal abscess may follow.
persistent urachal ligament
maintains tension on the bladder leading to incomplete filling and emptying. The elongated bladder with a pointed vertex is readily visible radiologically.
