Bright dot sign (atypical liver hemangioma)

Last revised by Juan Janse van Rensburg on 22 Mar 2021

The bright dot sign refers to the presence of a bright dot within a lesion which remains hypoattenuating on arterial and portal venous phase CT, corresponding to early nodular enhancement seen on dynamic MRI of liver hemangioma

This can be used as an indicator that the lesion in question is a hemangioma (and not a metastasis). Dynamic MRI should be confirmatory.
