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 her 8 of age.
Face ultrasound detected nothing in supine position. But in bending down of her head the left nasolabial groove disappears which is swollen and ultrasound detected a cystic lesion into the masseter space.
MSCT confirmed the cystic lymphangioma in the masseter space in two positions : supine and prone.
The girl seems to be pleased with the explanations but she denies any FNAC or puncture for sclerotherapy maybe causing any scare of her face.
The story which we learned about of the case is paid attention at something doubtful of the patient’ complaints and trying to find it out.
