A proper detection of atypical epithelial hyperplasia (component of FCC) without missing the coexistent malign disease is the main problem in evaluating the FCC-affected patients. For some patients, it is not enough to use only mammography and ultrasonography in pursuit or decision biopsy. Magnetic resonance imaging (MRI) may be important in these patients. Nevertheless, the MRI features of FCC are not clearly known because there are very few studies specifically focused on FCC. Studies reporting on MRI of breast fibrocystic changes are very scarce and their MRI findings are not clearly known. The aim of this study was to determine the MRI characteristics of fibrocystic changes. Twenty-six patients with pathologically proven fibrocystic changes of the breast were retrospectively reviewed. The MRI study was performed using 1.5 T MR scanner with a phase array bilateral breast coil. The imaging protocol consisted of pre-contrast T1-weighted imaging and bilateral dynamic 3D contrast-enhanced imaging. The morphologic and kinetic features of fibrocystic changes on MRI were evaluated. Twenty-four patients showed benign enhancement kinetics (type 1), while 2 patients showed malignant enhancement kinetics (type 2). To our knowledge, the analysis of enhancement kinetics may be more useful in identifying atypical epithelial hyperplasia and cancer from other breast lesions provided that corrections are made for the true phase of menstrual cycle (Tab. 1, Fig. 1, Ref. 10).

The location of a pseudocyst in the liver is an exceptional event. We report here a case developing right and left intrahepatic pseudocyst following acute biliary pancreatitis. Ultrasound and computed tomography scan revealed a 13-cm right and two 4-cm left intrahepatic collections. Percutaneous puncture permitted us to detect a high level of amylase in the collection, confirming the diagnosis of intrahepatic pseudocyst. Percutaneous drainage resulted in 3000 mL of fluid discharge. The mechanism involved in this patient was rupture of the pancreatic pseudocyst in the retroperitoneal cavity and erosion reaching the right hepatic parenchyma retroperitoneally posterior to the hepatoduodenal ligament and the left hepatic parenchyma via the hepatogastric ligament. Besides, endoscopic sphincterotomy was performed with endoscopic retrograde cholangiopancreatography for cholangitis. After performing endoscopic sphincterotomy, the cysts in the left lobe resolved dramatically. Intrahepatic pseudocyst should be kept in mind when an intrahepatic collection is found in a patients with chronic or recent episode of acute pancreatitis. Computed tomography and high level of amylase in the collection plays an important role for diagnosing this complication. In case of abdominal pain and large intrahepatic pseudocyst, percutaneous drainage can be performed. Source
