Presentation
Right sublingual swelling.
Patient Data
Right sublingual small well defined lobulated soft tissue lesion eliciting low signal on T1 and high signal on T2 & STIR WI showing small internal phlebolith of low signal intensity. It shows post contrast enhancement.
Right sublingual tiny faint calcific foci.
Clinical photograph of the patient's mouth showing the right sublingual bluish vascular swelling.
Case Discussion
Low-flow venous malformations (eg, cavernous hemangiomas) in the head and neck most frequently occur in the floor of the mouth or the buccal space. On MR imaging and CT they appear either:
- predominantly cystic lesions eliciting high-signal-intensity on T2-fat-saturated images
- or solid lesions with isointense signal similar to the muscular signal intensity
The lesions may contain calcified phleboliths, which appear as round foci signal on MR of dark signal and show high attenuation on CT images as in our case.
