Tailgut cyst: MRI evaluation.

OBJECTIVE: The purpose of our study was to evaluate the MRI features of tailgut cysts in five patients. CONCLUSION: Our results suggest that MRI may be useful in the diagnosis of tailgut cyst. A multilocular cystic mass in the presacral space is a characteristic MRI finding of tailgut cyst, which may also be revealed as a cystic mass consisting of a large cyst accompanied by a small peripheral cyst. However, further studies are necessary to establish the usefulness of MRI for evaluating tailgut cysts.

Complications of pyogenic hepatic abscess: computed tomography and clinical features.

The purpose of this pictorial essay is to describe the computed tomography (CT) and clinical findings of the various complications of pyogenic hepatic abscesses. The CT and clinical findings of 81 patients who had a confirmed pyogenic hepatic abscess were analyzed retrospectively. Of the 81 patients, 21 cases of various complications from the pyogenic hepatic abscesses were encountered in 17 patients (21%). Two types of complications were observed in 4 patients. These complications included rupture into the pericardial cavity (n = 1), pleuropulmonary complications (n = 11), rupture into the gastrointestinal tract (n = 1), rupture into the peritoneal cavity (n = 3), rupture into the retroperitoneum (n = 1), vascular complications (n = 3), and biliary complications (n = 1). A knowledge of these complications is important for an early diagnosis and appropriate management.

Anomaly of the portal vein with total ramification of the intrahepatic portal branches from the right umbilical portion: CT features.

PURPOSE: To describe CT findings of portal vein anomaly with total ramification of the intrahepatic portal branches from the right umbilical vein. METHODS: Retrospective analysis was performed in 6 patients with portal vein anomaly with total ramification of the intrahepatic portal branches from the right umbilican vein. We analyzed the position of the umbilical portion of the portal vein and ligamentum teres, and determined the intrahepatic branching pattern of the portal vein. RESULTS: The umbilical portion and ligamentum teres were deviated to the right and seen above the gallbladder fossa in all 6 patients. All major braches of the portal vein ramified from the right umbilical vein in all 6 patients. CONCLUSION: The possibility of this portal vein anomaly should be kept in mind when hepatic resection or partial liver transplantation is required.

Computed tomography and sonographic findings of hepatic metastases from gastrointestinal stromal tumors after chemotherapy.

OBJECTIVE: The purpose of this study was to evaluate the computed tomography (CT) and sonographic findings in patients with hepatic metastases from gastrointestinal stromal tumors (GISTs) after STI-571 treatment. METHODS: Computed tomography and sonographic findings of 8 lesions in 6 patients with hepatic metastases from GISTs that were treated with STI-571 were retrospectively analyzed. The change in size, attenuation, and echogenicity of the hepatic metastases from GISTs after STI-571 treatment was evaluated. RESULTS: After treatment with STI-571, the hepatic metastases were decreased in size and the attenuation of the hepatic metastases was homogeneously hypodense on CT. Sonography revealed the hepatic metastases to be centrally cystic with a thin wall (n = 4) or predominantly solid (n = 4) after STI-571 treatment. On color Doppler sonography, no blood flow was identified within the solid portion of the mass. CONCLUSION: After treatment with STI-571, although the hepatic metastases from GISTs exhibit a cystic appearance on CT, they may appear as solid masses on sonography.
