Presentation
Upper neck swelling,
Patient Data
Multispatial homogenous soft tissue density lesions are seen affecting the right sublingual regions and the right parapharyngeal region posteromedial to the right carotid sheath. The lesions show homogenous moderate post-contrast enhancement.
Enlarged cutaneous and subcutaneous venous varices involving the upper neck, notably at the right side of the neck with dilated draining internal jugular veins, more the right one. No definite enlarged arterial feeders identified.
There is cystic swelling inferolateral to the right parotid gland with no enhancement suggestive of associated lymphatic malformation.
Case Discussion
Combined vascular malformations consist of two or more types of vessel malformations (capillary, venous, lymphatic or arteriovenous). 50% of vascular malformations are venous malformations. Lymphatic malformations are less common and combined lymphatic and venous malformations are rare.
