Figure 1

Patient case MRI and FNA of liver lesion. (a) MRI of the abdomen showed a bulky gallbladder tumor measuring 5.6 cm with direct extension into the liver, innumerable hepatic and periportal nodal metastases which exerted mass effect on the cystic duct, and peripancreatic and right diaphragmatic nodal involvement. (b) Ultrasound-guided biopsy of a metastatic liver lesion shows small and fragile epithelioid cells with little cytoplasm and fine chromatin. Abundant apoptotic bodies and mitotic figures were seen consistent with small cell carcinoma.
