Bilateral Hutch diverticula presenting as “Mickey Mouse bladder” in a child: A case report

Congenital bladder diverticula are rare in children. The Mickey Mouse bladder refers to a specific radiological sign that appears in bilateral paraureteral diverticula. We describe an 11-year-old boy presented with lower urinary symptoms. Imaging studies showed bilateral Hutch diverticula without vesicoureteral reflux. Urodynamic studies showed detrusor overactivity with bladder-sphincter dyssynergia. The patient was managed conservatively with clean intermittent catheterization and anticholinergic medication, and he had a significant clinical response without surgery. This case emphasizes the role of functional studies and supports conservative management in cases where bladder dysfunction is the major underlying problem. • Bilateral hutch diverticula may manifest as a 'Mickey Mouse bladder'. • Bladder dysfunction can lead to symptoms and residual urine. • Urodynamic studies are essential before surgery. • Conservative management can eliminate the need for diverticulectomy.
