case_images: A 20-year-female who presented with gradual neck swelling and mild pain for 4 months. Sagittal grayscale ultrasonography image showing well-defined thick-walled cystic lesion (arrow) in the intramuscular plane in the distal SCM (asterisk) with eccentric hyperechoic foci (arrowhead) within the cavity and surrounding edematous changes.

case_images: An eccentric tiny hyperechoic focus (scolex) was seen within the lesion (Figure 1).
case_images: Axial noncontrast computed tomography image of the neck at the level of T1 vertebra showing slightly hypodense cystic lesion with a small area of hyperdensity within the lesion (arrow).

case_images: Noncontrast computed tomography (CT) scan of the brain was normal; whereas, the neck showed an ill-defined hypodense lesion in the right sternocleidomastoid muscle with a tiny eccentric hyperdense focus within it, which was suggestive of the scolex (Figure 2).
