Introduction
Lipoblastoma is a rare benign tumor predominantly found in the pediatric population, with the majority of cases identified in children under 3 years of age and more commonly in males (1). It usually presents clinically as a painless, rapidly expanding soft tissue mass (2). However, when the growth compresses adjacent structures, symptoms may develop (1, 2). Various diagnostic imaging techniques such as ultrasound, CT (computed tomography), and MRI (magnetic resonance imaging) are crucial in diagnosing this condition, as these modalities reveal the main fatty consistency leading to the consideration of differential diagnoses (2–4).
Lipoblastoma typically originates in the subcutaneous tissues of the extremities and trunk, though occurrences in the sacral area are comparatively rare (3, 5). The case described here involves a biopsy-confirmed presacral lipoblastoma in a child who experienced urinary retention due to the tumor’s location and growth. This presentation highlights the importance of recognizing the potential for lipoblastoma to manifest in less common locations and the implications this has for symptom development and treatment planning.
