Presacral Lipoblastoma Presenting With Urinary Retention

Area of Science:

• Pediatric Oncology
• Surgical Pathology
• Urology

Background:

• Lipoblastoma is a rare, benign fatty tumor typically affecting infants and young children.
• While commonly found in the limbs or trunk, lipoblastomas can rarely occur in the presacral space.
• Large presacral tumors can lead to significant infiltrative and obstructive symptoms.

Purpose of the Study:

• To report a unique case of a large presacral lipoblastoma presenting as recurrent urinary retention in a 1-year-old infant.
• To emphasize the importance of considering rare tumor locations and presentations in pediatric diagnostics.
• To highlight the successful surgical management of this rare pediatric neoplasm.

Main Methods:

• Case report of a 1-year-old infant with a 4-month history of recurrent urinary retention.
• Diagnostic imaging to identify the presacral mass.
• Surgical excision of the presacral lipoblastoma.
• Histopathological confirmation of the diagnosis.

Main Results:

• A large presacral lipoblastoma was identified as the cause of the infant's urinary retention.
• The tumor was successfully resected.
• Post-operative recovery was uneventful, with resolution of urinary symptoms.

Conclusions:

• Presacral lipoblastoma is a rare entity that can present with urinary retention in infants.
• Surgical resection is an effective treatment for symptomatic presacral lipoblastomas.
• This case underscores the diagnostic challenge posed by rare tumor locations and presentations in pediatric patients.
