We report on a woman who presented with urinary incontinence, covered
exstrophy and an abdominal mass. Radiographic studies and cystoscopy c
onfirmed that the anterior abdominal mass did not communicate with,the
bladder or colon and that the gastrointestinal tract was normal. Subs
equent surgical resection of the mass and Young-Dees-Leadbetter bladde
r neck reconstruction were performed. Histological examination of the
mass revealed colonic mucosa. The etiology of the covered exstrophy an
d sequestered colonic remnant is discussed.
