Cures for advanced hepatocellular carcinoma (HCC) with portal vein tumor thrombosis (PVTT) are rare and difficult. We report a case of pathologically confirmed complete remission of HCC induced by hepatic arterial infusion chemotherapy (HAIC). A 45-year-old male patient had a massive HCC in the right lobe of the liver and tumor thrombus in the right and main portal veins. He achieved a partial response after two cycles of HAIC with 5-fluorouracil (750 mg/m2) and cisplatin (25 mg/m2). After the completion of six cycles he received a curative partial hepatectomy, and histopathology revealed complete necrosis without any viable tumor cell. He was in good health at a 4-month follow-up. These results suggest that this regimen is a promising therapeutic modality for the treatment of advanced HCC with PVTT.

A pathologic splenic rupture is rare, occurring primarily in a spleen affected by infective, hematological, and neoplastic disease. To the best of our knowledge, no prior reports of a pathologic splenic rupture due to scrub typhus exist. Intrasplenic pseudoaneurysms and focal infarctions are visible on an initial CT scan. Moreover, the spontaneous splenic rupture occurred a week later. We report a case of nontraumatic-splenic rupture in a patient with scrub typhus.

PURPOSE: The objective of this study is to evaluate the efficacy and safety of an ultrasound-guided core needle biopsy with an 18G cutting needle in patients suspected of having a pancreatic disease by analyzing the diagnostic performance and complication rate. MATERIALS AND METHODS: The study population comprised 35 consecutive patients who underwent an ultrasound-guided core needle biopsy using a high-speed biopsy gun accompanied with an 18G cutting-type needle between May of 2001 and October of 2005. The diagnostic performance (i.e., the acquisition rate and diagnostic accuracy) and complications associated with core needle biopsies were evaluated for its efficacy and safety. RESULTS: Thirty-six sessions of ultrasound-guided core needle biopsies were performed in 35 consecutive patients. All patients, except two (serous cystadenoma and autoimmune pancreatitis) were diagnosed with various subtypes of pancreatic cancer. The acquisition rate and diagnostic accuracy were 97% (35/36) and 94% (34/36), respectively. A complication occurred only in one patient (3%), which further proved to be a delayed complicaton (i.e., needle tract implantation). CONCLUSION: According to our findings, the ultrasound-guided core needle biopsy is a viable and safe method for the dignosis of pancreatic diseases. Moreover, it enables the diagnosis of the pancreatic cancer subtype.

A portal vein aneurysm is divided into two groups; an extrahepatic portal vein aneurysm and an intrahepatic portal vein aneurysm. The morphology of an aneurysm can be divided into types such as fusiform, bilobulated and saccular. A saccular aneurysm that arises from the intrahepatic portal branch is extremely rare. We report here a case of a saccular aneurysm of the intrahepatic portal branch mimicking an intrahepatic hypervascular mass, as seen on a dynamic CT scan, with the radiological findings.

Splenic infarction occurs when parenchymal ischemia of the spleen is evoked by an occlusion of the arterial or venous circulation. The most common causes include infiltrative hematological disease and thromboembolic conditions, but a hypotensive splenic infarction may be a rare cause of splenic infarction. A 62-year-old female patient presented with a hypotensive splenic infarction after massive bleeding. CT showed geographic low-density lesions in the central part of the spleen on the tissue equilibrium phase of dynamic CT. Usually, a depressed scar occurs in the course of healing of a splenic infarction. However, in this case recovery of blood flow and regeneration of the infarcted spleen was seen during the follow-up CT scans. We report a case of hypotensive splenic infarction with a review of the literature.

Schwannoma is a benign neurogenic tumor arising from the nerve sheath, and it presents as a well defined mass. Isolated gastrointestinal schwannoma is a relatively rare finding and schwannoma of the appendix is extremely rare. We report here on a case of schwannoma that arose from the appendix, and this lesion was pathologically confirmed.

PURPOSE: Hypervascular hyperplastic nodules in those patients with chronic alcoholic liver disease and who are hepatitis B and C negative have recently been reported on. The purpose of this study was to correlate the radiologic and pathologic findings with the clinical significance of these hypervascular hyperplastic nodules in chronic alcoholic liver disease. MATERIALS AND METHODS: The study included eight hypervascular nodules of seven patients with chronic alcoholic liver disease, and these patients had abused alcohol for more than 20 years. Eight hypervascular nodules were seen on the arterial phase of dynamic CT scans, but the possibility of HCC was excluded pathologically (n=4) or clinically. The radiologic and pathologic findings, and the changes of these nodules on follow up CT scans were retrospectively analyzed. RESULTS: All nodules showed good enhancement on the arterial phase. The tissue equilibrium phase of the dynamic CT scans showed isodensity in seven patients and low density in one patient. Ultrasound scans revealed hypoechoic findings for three nodules, isoechoic findings for two nodules, hyperechoic findings for one nodule, and two nodules were not detected. Angiograms (n=6) showed late incremental tumor staining, and all the nodules were well seen on the sinusoidal phase. CT during hepatic angiography (n=4) showed well stained tumor. CT during arterial portography (n=4) showed no defect in three nodules and nodular defect in one nodule. The MR images (n=3) showed low signal intensity in two nodules and iso-signal intensity in one nodule on T2WI. Five of six cases for which follow up CT scans were performed showed decrease in size and one was disappeared. CONCLUSION: Radiologically, it is often difficult to differentiate the hypervascular hyperplastic nodules seen in the chronic alcoholic liver disease from hepatocellular carcinoma, and histological confirmation is needed for excluded hepatocellular carcinoma. However, late tumor staining during the sinusoidal phase without any blood supply by feeding vessels or any arterioportal shunt on the angiogram, isodensity during the tissue equilibrium phase of dynamic CT and low signal intensity on T2WI may suggest the presence of hypervascular hyperplastic nodule.
