Hemangioma - intramuscular

Case contributed by Dr Ammar Haouimi

Presentation

Painless swelling of the left lateral aspect of the neck.

Patient Data

Age: 30 years
Gender: Male
Ultrasound

There is a hypoechoic soft tissue mass containing foci of calcification (phleboliths) within the left sternocleidomastoid muscle, highly vascularized on color doppler.

MRI

Asymmetrical size of the sternocleidomastoid muscles (SCM), the right is larger than the left with no fatty infiltration (may represents an anatomical variant). There is a small ovoid soft tissue mass within the left SCM, measuring (25x20x10 mm) at the level of C5 of intermediate signal intensity on T1WI (higher than that of the muscles), high signal intensity on T2WI, containing foci of low signal (phleboliths) with high signal on DWI and ADC. The postcontrast sequences show a progressive and heterogeneous enhancement.

Case Discussion

The MRI appearance is highly suggestive of an intramuscular hemangioma within the sternocleidomastoid muscle.
