Spontaneous disappearance of a cystic lesion in a 5-year-old boy between 2017 and 2018, which led to the diagnosis of this lesion as a most likely liver lymphatic malformation. a Ultrasonography shows biloculated homogeneous cyst (arrow), which vanished one year later (star).

The main differential diagnosis of this lesion would be two fused simple hepatic cysts or mesenchymal hamartoma
