Case Discussion
Lymphatic malformations are benign lesions of vascular origin that show lymphatic differentiation. It is considered the lymphatic equivalent of a hemangioma of blood vessels.
Fluid-fluid levels may be seen if complicated by hemorrhage. Signal characteristics include:
- T1: can be variable especially dependent on protein content
- T2: usually high signal
