USG showed a thickened sternocleidomastoid muscle on the left side; it had a fusiform appearance and heterogenous echotexture. The fibrillar structure of the muscle fibers was, however, maintained. The right sternocleidomastoid muscle appeared normal. There was no cervical lymphadenopathy.
Case Discussion
The sonographic features and the clinical findings are compatible with fibromatosis colli (pseudotumor of the sternocleidomastoid muscle).
