The focal hepatic hot spot sign with lung cancer in computed tomography

摘要

Key message The focal hepatic hot spot sign appears as an area of intense focal wedge‐shaped enhancement of the quadrate lobe (segment IVa) of the liver in the arterial and venous phase. If this sign appears on enhanced computed tomography of the abdomen, obstruction of thoracic central venous must be considered, especially when clinical symptoms are unclear.
