Ultrasound examination: (Figure 1) of the neck revealed hypoechoic lesion located medially to the sternocleidomastoid muscle and inside trapezoid muscle.
Axial, non-contrast computed tomography scan shows lesion with a rim of calcification at the periphery ("zonal phenomenon").

Computed tomography: (Figure 2) scans demonstrated a low-attenuating soft tissue mass, 30x28 mm in size, with peripheral calcification, located within left splenius colli and medially to levator scapulae muscle, displacing the semispinalis capitis and semispinalis colli muscles,.
Axial, T1-weighted image reveals hyperintense SI of the lesion with a low-SI rim.

Magnetic Resonance Imaging with angiography: (Figures 3-6) revealed a relatively well - defined left-sided mass measuring 28x24x26 mm in diameter.
Axial, T2-weighted FS image shows intermediate- to high-SI of the lesion with a low-SI rim.

Magnetic Resonance Imaging with angiography: (Figures 3-6) revealed a relatively well - defined left-sided mass measuring 28x24x26 mm in diameter.
Sagittal, T2-weighted image shows intermediate SI of the lesion with a low-SI rim. There are perilesional areas of high SI along adjacent muscle fibers - edema.

Magnetic Resonance Imaging with angiography: (Figures 3-6) revealed a relatively well - defined left-sided mass measuring 28x24x26 mm in diameter.
Coronal, T1-weighted image after administration of gadolinium contrast demonstrates marked enhancement within the lesion.
