title: Postmortem percutaneous core biopsy of the liver.
abstract: Unexpected deaths related to significant hepatopathology are encountered daily by forensic pathologists. After investigation, a decision will be made regarding whether or not to perform an autopsy. In considering the options available to assess the degree of hepatopathology, a study was undertaken to evaluate the potential role of percutaneous core biopsy of the liver at the time of postmortem examination. Postmortem percutaneous hepatic core biopsy was attempted at the time of external examination in 28 nonconsecutive cases examined at the Office of the Chief Medical Examiner, State of Maryland; hepatic tissue was obtained in 26 cases. In 21 of these cases, hepatic tissue was obtained during subsequent partial or complete autopsy and submitted for histologic correlation. There was complete histologic correlation of tissue obtained via percutaneous biopsy with hepatic tissue obtained by open biopsy in 18 of 20 cases (86%). Significant hepatopathology was identified by core biopsy in 5 of 9 cases (56%) with a history of ethanol abuse and in 8 of 19 cases (42%) with a negative ethanol history. The sensitivity of this technique was 82% and the specificity was 100%. This study has shown that core biopsy of the liver can provide information related to the cause of death in cases with and without a history of alcohol consumption. In cases in which a complete autopsy is deferred because of familial religious objections, infectious disease, or time/budgetary constraints, this modality can be used to obtain diagnostic tissue.
