Successful surgical resection of ruptured cholangiolocellular carcinoma: A rare case of a primary hepatic tumor.

Spontaneous rupture is one of the most fatal complications of hepatic tumors such as hepatocellular carcinoma. In fact, many studies have shown that the in-hospital and 30-d mortality rates are as high as 25%-100%. Cholangiolocellular carcinoma (CoCC) is a rare primary hepatic tumor, usually small in size, that is thought to originate from the ductules and/or canals of Hering. Here, we present a case of spontaneous rupture of a CoCC that was successfully resected by radical surgery. Although CoCC is a rare primary hepatic tumor, it demonstrates certain specific clinical features, including a better prognosis than for other primary liver cancers, and thus should be distinguished from those other cancers. Moreover, CoCC can appear as a ruptured huge tumor, and when it does, radical hepatectomy can be an effective measure to achieve both absolute hemostasis and curability of tumor.

[Early diagnosis of capecitabine-induced acute leukoencephalopathy by using diffusion-weighted MRI].

A 63-year-old woman with colon cancer who was treated with capecitabine as adjuvant chemotherapy presented with vertigo on day 5, and dysarthria and dysphagia on day 7 of the treatment. Diffusion-weighted magnetic resonance imaging of the brain revealed high signal intensity in the corpus callosum and corona radiata. The patient was diagnosed with acute leukoencephalopathy, and the capecitabine treatment was discontinued. Her symptoms recovered immediately. On the basis of these findings, it can be concluded that diffusion-weighted imaging is useful for the early detection and diagnosis of acute leukoencephalopathy.
