  • Also known as lymphangioma
  • Congenital developmental anomalies of the lymphatic system forming micro- or macrocytstic lesions (Wiegand et al. 2022; Bertino et al. 2021)
  • Associated with Proteus and CLOVES syndrome (Wiegand et al. 2022)
  • Most commonly present in head and neck region but may be in other lymphatic-rich areas as well (Wiegand et al. 2022)
  • Usually presents within first two years of life but may have a delayed presentation in adulthood (Wiegand et al. 2022)
    • Larger lesions may be seen on prenatal imaging (Bertino et al. 2021)
  • Symptoms include minimal swelling to possible airway obstruction, impaired oral feeding, macroglossia, loss of vision, and pain (Wiegand et al. 2022)
  • Acute enlargement may occur with infection, trauma, or hemorrhage; otherwise, it generally grows proportionally as the patient grows (Wiegand et al. 2022)
  • On CT: Fluid densities, poorly-circumscibed with or without fluid levels, no enhancement with contrast
  • On MR: Hypointense on T1 unless hemorrhage or abscess present; hyperintense on T2; post-contrast T1 is non-enhancing unless infected
