Figure 3. 35-year-old man with haemangioma in the right parotid gland. (a) Transverse grey-scale ultrasound of the right parotid gland shows a heterogeneous hypoechoic mass (white arrows) with sinusoidal spaces (arrowheads) and phlebolith (black arrow). (b) Axial spin-echo T₁ weighted MRI (450/13/2) shows a mass involving superficial and deep lobes (arrows) which shows signal intensity similar to muscle. (c) Fat-suppressed fast spin-echo T₂ weighted MRI (2500/120/2) shows markedly hyperintense signal intensity of the right parotid mass. Internal small round (arrows) and serpiginous (arrowhead) signal voids represent phleboliths and small vessels within the lesion, respectively. A similar smaller lesion is seen in right submandibular region (white arrow). (d) Fat-suppressed spin-echo T₁ weighted MRI (520/13/2) shows enhancement of the intraparotid lesion after intravenous gadolinium administration.(e) ^99mTechnetium pertechnetate labelled red blood cell scan in anterior acquisition shows red cell sequestration in right parotid region (arrow). Smaller areas of red cell sequestration are also demonstrated in right submandibular region (arrowhead) and left tongue base (open arrow).
