A 28 year-old girl with a doubtful mass at her left face which only appears in prone position for 20 years. That mass is yet diagnosed from many clinics since 8 years old.
Fig 1: Swollen left cheek and unclear the left nasolabial groove were in bending and sitting position.
Face ultrasound detected nothing in supine position. But in bending down her head the left nasolabial groove disappears. Then the left cheek was swollen and ultrasound revealed a #35x15mm echoic cystic lesion into the left masseter space.
MSCT non CA confirmed the cystic lymphangioma in the left masseter space in two positions : supine (upper line) and prone (lower line)
The girl was pleased with the explanations but she denies any procedure of FNAC or puncture for sclerotherapy that may causing any scar of her face.
The cystic lymphangioma in the masseter space is a rare entity. The story which we learned about of the case is paid attention at something doubtful of the patient’ complaint and trying to find it out. In that case it only was the appropriate position to detect a ghost mass on the left cheek of the nice girl.
