Cystic hygroma vs. occipital meningocoele

Dr Aditya Shetty et al.

Cystic hygroma and occipital meningocoele are both differential diagnosis for an antenatally detected cystic collection noted on the posterior aspect of the head and neck.

A simple differentiation can be made based on the contents and presence of septations:

  • cystic hygroma will present as well defined anechoic thin walled cyst with multiple septations and a characteristic midline septation representing the nuchal ligament
  • an occipital meningocoele will appear as a well defined anechoic area with no septations and is seen in direct continuity with a defect in the calvarium
