Angiolymphatic Malformation


MR – Infiltrative cystic mass with mildly heterogeneous signal.


Lymphatic malformations in the head and neck result from maldevelopment of the cervical lymphatic system that arises as paired jugular lymph sacs sprouting from the primitive jugular venous plexus at 6 weeks gestation. Lymphatic malformations are classified as either macrocystic or microcystic; macrocystic lymphatic malformations are more common and are believed to arise from early sequestration of embryonic lymphatic channels. These lesions are frequently infiltrative. Lymphatic malformations are formed by multiple cystic spaces lined by endothelial cells separated by minimal stroma.
