Hygroma colli

Cystic

hygroma and potential airway obstruction in a newborn: a case report and review of the literature. Follow-up magnetic resonance imaging of neck showing increase in size of the cystic hygroma with further compression of the structures of the neck.

Robot-assisted

excision of cervical cystic hygroma through a retroauricular hairline approach: a case report. Neck computed tomography scan with contrast enhancement. a axial scan and b coronal scan; there is a 3 cm × 3 cm sized, well-encapsulated homogenous low-density mass in the left posterior triangle neck area (arrows)

Cystic

hygroma and potential airway obstruction in a newborn: a case report and review of the literature. Initial magnetic resonance imaging of the neck showing right sided cystic hygroma, pushing the neck structures to the left.

Thyroglossal

duct pathology and mimics. Lymphangioma. a Axial contrast-enhanced CT image demonstrates a non-enhancing multilocular, trans-spatial fluid-attenuation mass centered in the left neck base with mass effect and rightward displacement of trachea and esophagus. Note the fluid-fluid levels indicative of prior hemorrhage (arrow), distinguishing this lesion from a thyroglossal duct cyst. b Axial T2-weighted MR image in a different patient demonstrates a trans-spatial multiseptated cystic mass extending from the right lateral infrahyoid neck across the anterior aspect of the thyroid cartilage
