Radiological appearance of diaphragmatic mesothelial cysts.
BACKGROUND
Diaphragmatic mesothelial cysts are congenital lesions that derive from coelomic remnants.


OBJECTIVE
To describe their radiological appearance on US, CT and MRI.


METHODS
Four children (aged 7-14 years) who underwent surgery and for whom there was pathological confirmation of the diagnosis. Five more children (0-12 months old) who were managed conservatively, but for whom there was a high degree of suspicion for this diagnosis.


RESULTS
All lesions presented as a cystic mass between the thoracic wall and the liver, in the right posterolateral costophrenic angle. Some lesions showed subtle evidence of their extrahepatic location.


CONCLUSIONS
The radiological findings identified are highly suggestive of diaphragmatic mesothelial cyst.
