Patient Data
Gender: Female
From the case:
Liver hemangioma - with light bulb sign
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/26334/annotated_viewer_json?lang=us"}
CT scan: non-contrast, arterial phase, portal venpus phase and delayed phase. There is a well-circumscribed and low attenuation lesion (on pre-contrast image) that has a peripheral centripetal enhancement on dynamic contrast phases.
From the case:
Liver hemangioma - with light bulb sign
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/26333/annotated_viewer_json?lang=us"}
Hepatic mass homogeneously hypointense relative to the liver on T1-weighted and markedly hyperintense (lightbulb sign) on T2-weighted images relative to the liver.
Case Discussion
The light bulb sign of a hepatic hemangioma refers to marked hyperintensity seen on heavily T2 weighted sequences that has been likened to a glowing light bulb.
