Brain metastasis from intrahepatic cholangiocarcinoma is rare. To the best of our knowledge, only a few cases have been reported. The biological behavior was complex, and treatment requires further investigation.
A 62-year-old woman complained of left limb weakness. Abdominal computed tomography showed a 5.0 cm × 5.6 cm lesion in the left lobe of the liver. Tumor markers were normal. Serological analysis indicated absence of hepatitis virus. Brain magnetic resonance imaging revealed a 1.0 cm × 1.3 cm mass in the right frontal lobe. Intrahepatic cholangiocarcinoma with brain metastasis was diagnosed by our liver cancer multidisciplinary team. After sufficient preparation, the patient underwent partial frontal lobotomy and left hemihepatectomy. Histopathological results confirmed that both the lesions were cholangiocarcinoma. Six cycles of gemcitabine combined with S1 were administered. During a 39 mo postoperative follow-up, no sign of local recurrence or distant metastasis was observed.
This case expands our knowledge concerning the complex and heterogeneous nature of tumor metastasis.
Core Tip: Intrahepatic cholangiocarcinoma is the second most common type of primary liver cancer, but metastasis to the brain is rare. Because of the low prevalence, the treatment and biological behavior are still unclear and require further study. In this work, we report a 62-year-old patient with intrahepatic cholangiocarcinoma with brain metastasis. Operation-based comprehensive treatment was recommended by our liver cancer multidisciplinary group. There was no local recurrence or distant metastasis after 39 mo of postoperative follow-up. We propose that each cancer patient should be treated regardless of disease stage, and a multidisciplinary team is important.
