Abstract

Although liver granulomata mimicking metastatic nodules have been reported previously, these have not been related to previous percutaneous transhepatic cholangiography and biliary drainage. We describe four cases where necrotising granulomata, apparently secondary to previous PTBD, have necessitated liver biopsy and frozen section examination at the time of subsequent planned cancer resection, to exclude tumour metastases. Necrotising granulomata were diagnosed on frozen section in 3 patients, but in one, frozen section offered a diagnosis of malignancy with necrosis, but paraffin sections showed features of a necrotising granuloma. Knowledge of this potential pitfall, with surgeons and pathologists being aware of these lesions caused by PTC, should help prevent misinterpretation.
