Case 14: Biopsy Tract

Diagnostic Category:

Clinical Presentation:

59 year on man on liver transplant list.

CT: Linear hypovascular zone

Imaging Findings:

CT shows linear avascular hypodense zone in typical location laterally in the right lobe in almost horizontal orientation, corresponding to the trajectory of a "blind" liver biopsy following sonographic marking of the skin. Note biopsy tract is located in between two ribs, as the trajectory had to be through an intercostal space at the time of biopsy.
