Abstract
Inguinal hernia may contain the bladder as one of its contents, while
bilateral inguinal bladder herniation is rare. Urinary obstruction and
obesity are associated with increased abdominal pressure and are risk
factors of bladder herniation. Clinicians should be aware of the bladder
hernia in elderly with chronic dysuria and obesity.
Key words: bladder hernia, benign prostatic hyperplasia
An 80-year-old male, whose body mass index was 25.9
kg/m2, presented with bilateral groin pain despite no
tenderness or palpable masses in either inguinal region. He had an
8-year history of dysuria due to benign prostatic hyperplasia. Computed
tomography showed bilateral inguinal hernias appearing as fluid-filled
structures continuous with the bladder (Figure 1). The pain was not
relieved by urination. Open surgical hernia repair was therefore
performed.
Inguinal hernia may contain the bladder as one of its
contents1), while bilateral inguinal bladder
herniation is rare. Horizontal section images of
bilateral inguinal bladder hernias
are described as “Pelvic Mickey Mouse Sign” because they resemble the
Walt Disney character2). Chronic urinary obstruction
and obesity are associated with increased abdominal pressure and are
risk factors of bladder herniation. Clinicians should be aware of the
inguinal bladder hernia as a cause of groin pain in middle-aged and
older male with chronic dysuria and obesity.
