Clinical Features:

A 23 years old female patient came with a left cheek swelling.

Ultrasound Features:

- A well-defined oval slightly lobulated hypoechoic mass of heterogeneous echotexture with multiple internal cystic spaces is noted within the muscular compartment of the left cheek, just medial to the medial border of the left parotid gland.

- No extension beneath the muscular compartment.

- Color Doppler shows, weak vascular flow signals of predominantly venous origin.

- Supplying artery arising from adjacent facial vessel show moderate impedance flow (RI: 0.7).

Remember:

- According to newer nomenclature (ISSVA classification of vascular anomalies), these lesions are merely known as slow flow venous malformations.

- It is probably helpful to include the word 'hemangioma' in reports as this term is most familiar to many clinicians.
