Key clinical message
Lipoblastoma is a rare fatty tumor in the pediatrics population that
arises from embryonic white fat cells. They typically occur in the
extremities and trunk, but are rare in the presacral space. When the
lesions attain sufficient size, they can cause a multitude of
infiltrative and obstructive symptoms. In this report, we present the
case of a 1-year-old infant who presented with recurrent urinary
retention for 4 months due to a large presacral fatty mass, which later
proved to be a lipoblastoma. An open surgical resection successfully
treated the patient. This case is unique as it highlights the lesion’s
rare location in the presacral space and the possibility of such lesions
presenting with urinary retention.
