anaerobic infection is present. Thickening of the wall of the umbilical remnant structure
usually occurs, particularly with chronic infections.
Urachal abscess
In most foals, multiple internal umbilical remnants are involved in the infectious
process. The urachus is the most common structure affected in foals. If the umbilical
vein is infected the vein should be carefully scanned up to and including the liver to
evaluate the extent of the infection.
Uroperitoneum
Ultrasonographic evaluation of foals with suspected uroperitoneum results in
a rapid confirmation of the diagnosis and localization of the probable site of the
defect. A large quantity of anechoic fluid is present with the gastrointestinal viscera
floating in the fluid. In foals with a ruptured bladder, the bladder is collapsed, folded
on itself and contains little or no fluid (urine).
