Pediatric Liposarcoma
Etiology:
Imaging: Features that favor liposarcoma are thick septations, enhancement, size greater than 10 centimeters
Imaging MRI: — Some contain very little fat — Variable amounts of fibrous septae and myxoid matrix determine appearance — Indistinguishable from lipoblastoma – rely on age to differentiate
DDX: Cannot be reliably distinguished from lipoblastoma but lipoblastoma is much more common
Complications:
Treatment:
Clinical:
Radiology Cases of Liposarcoma
Axial (above left) and sagittal (above right) TI MRI without contrast of the face shows a high signal intensity mass in the left pharyngeal and masticator and parotid spaces that is displacing the palatine tonsils and airway. Coronal T1 MRI with contrast with fat supression (below left) and without fat supression (below left) shows the mass to not enhance. The mass follows fat signal on all sequences.
