Fig. 1A. 54-year-old man with gastrointestinal stromal tumor, metastatic to
liver. T2-weighted coronal MR image after radiofrequency ablation shows bright
fluid collection and mural nodule.
Fig. 1B. 54-year-old man with gastrointestinal stromal tumor, metastatic to
liver. Contrast-enhanced CT image obtained in supine position shows partially
drained collection with catheter in place (straight arrow). Anterior
low-density lesion represents another ablated tumor (curved arrow).
Note chronic left pleural collection.
Fig. 1C. 54-year-old man with gastrointestinal stromal tumor, metastatic to
liver. ERCP scan shows intracavitary leak (arrow) from left main
duct. Percutaneous biloma drainage catheter is seen laterally.
Fig. 1D. 54-year-old man with gastrointestinal stromal tumor, metastatic to
liver. Coronal positron emission tomography scan obtained 4 months after
biloma drainage shows no evidence of tumor (arrow).
