Bright dot sign (atypical liver haemangioma)
The bright dot sign refers to the presence of a bright dot within a lesion which remains hyperattenuating on arterial and portal venous phase CT, corresponding to early nodular enhancement seen on dynamic MRI of liver haemangioma.
This can be used as an indicator that the lesion in question is a haemangioma (and not a metastasis). Dynamic MRI should be confirmatory.
