The cysts do not characteristically enhance, although the septa, which are vascularized, show contrast material uptake. There may also be enhancement of the venous component in mixed malformations.

Can cystic lymph nodes be benign?

Repeated local infection involving a branchial cleft cyst may confer a radiological appearance similar to that of nodal metastasis of an SCC. 7 In one study, 31% of cystic nodal metastases were reported as benign in appearance, while 38% of branchial cleft cysts had aggressive features mimicking nodal metastases.

Are cysts seen on MRI?

What are epidermoid and dermoid cysts?

Epidermoid cysts are benign lesions, characterized by cystic spaces lined by simple squamous epithelium (epidermoid cyst), containing skin adnexa (“true” dermoid cyst) or tissues of all three germ layers (teratoid cyst). Head and neck constitute ~7% of all cases of epidermoid and dermoid cysts.

What does an epidermoid cyst look like on a CT scan?

The axial contrast-enhanced CT scan shows a cystic lesion in the midline in the floor of the mouth, with small discrete areas of fatty attenuation characteristically giving a “sac-of-marbles” appearance Epidermoid cysts usually show fluid-density material [Figure 10].

How do you identify a dermoid cyst on an ultrasound?

Ultrasound. As a useful tool to distinguish between an epidermal inclusion cyst and a dermoid cyst, if the lesion is not covered by periosteum, it is more likely to represent a dermoid cyst. On color Doppler, it may show twinkling artefact 8.
