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.
