Infarction of an accessory spleen secondary to splenic vein thrombosis in essential thrombocytosis

Accessory spleen is an incidental finding of no clinical significance in most patients. Essential thrombocytosis is a chronic, myeloproliferative disorder with a clinical course complicated by thrombotic episodes. We report on a case of essential thrombocytosis presented with infarction of the accessory spleen secondary to splenic vein thrombosis. © 2004 Elsevier Ltd. All rights reserved

Anatomic Variations of the Intrahepatic Bile Ducts: Analysis of Magnetic Resonance Cholangiopancreatography in 1,011 Consecutive Patients

Objectives: The aim of the study was to evaluate the frequency of anatomic variations of the hepatic duct bifurcation using magnetic resonance cholangiopancreatography (MRCP). Methods: A total of 1,160 consecutive patients, referred to our department for MRCP due to suspected pancreatobiliary disease or before liver transplantation, were reviewed retrospectively. A total of 149 patients with less than optimal results due to imaging limitations or secondary differentiations of bile duct anatomy were excluded from the study. The final study population was composed of 1,011 cases. Results: Of the 1,160 patients, 149 were excluded from the analysis. Typical biliary anatomy was observed in 79.4% of cases, but female potential living liver donors more frequently presented an anatomic variation. Typical anatomy was present in 75.7% of the females and 85.3% of the males (p < 0.05). Out of the remaining 1,011 patients, 208 (20.57%) were diagnosed with different levels of various anatomic variations of the intra-and extrahepatic biliary ducts. Of the 208 cases with diagnosed variations, 204 (98.07%) and 4 (1.92%) turned out to have 1 and 2 different variations, respectively. The trifurcation variant was observed in 81 cases (8.01%), while 73 subjects (7.23%) had an aberrant right biliary duct draining into the common hepatic duct. A right dorsocaudal branch draining into the left hepatic duct was present in 42 cases (4.15%). Four cases (0.4%) had 2 different variations and 8 (0.8%) had uncommon anatomic variations. Conclusions: Typical intrahepatic biliary anatomy is present in about 80% of the inhabitants of the Aegean region of Turkey, but anatomic variants seem to be more frequent in females as compared to males. Trifurcation was the most common anatomic variation in our study population. The presence of an aberrant right hepatic duct emptying into the common hepatic duct was the second most common observation amongst our findings. (C) 2014 S. Karger AG, Base

The role of dynamic subtraction MRI in detection of hepatocellular carcinoma

PURPOS

An evaluation of thyrotoxic autoimmune thyroiditis patients with triplex Doppler ultrasonography.

Objective: This study aimed to investigate the usefulness of blood flow parameters obtained from STA and CCA with Triplex Doppler ultrasonography (TDU) on patients with thyrotoxicosis. Materials and methods: This cross-sectional study included consecutive 24 patients with thyrotoxicosis and 18 healthy controls. The thyroid gland blood flow parameters were evaluated with TDU. Results: The thyroid volumes and FT3, TRAb, 4-h and 24-h radioactive iodine uptake (RAIU) levels of Group 1 were significantly high compared to those of Group 2. The thyroid volumes and FT3, FT4 and TSH levels of both Group 1 and Group 2 showed a statistically significant difference compared to Group 3. STA-PSV values for Group 1, Group 2 and Group 3 were 138 cm/s, 54 cm/s and 37 cm/s, respectively. STA-EDV values for these groups were 60 cm/s, 25 cm/s and 15 cm/s, respectively. PSVR values for these groups were 1.01, 0.45, 0.34 cm/s, respectively. EDVR values for these groups were 1.29, 0.70 and 0.49 cm/s, respectively. In Group 1, STA-PSV, STA-EDV, PSVR and EDVR values were significantly high compared to those of Group 2. RAIU levels showed a significant positive correlation with the STA-PSV, STA-EDV and PSVR. Conclusion: The thyroid gland blood flow parameters may be used in clinical diagnosis of patients with thyrotoxicosis. (C) 2014 Elsevier Inc. All rights reserved

The role of SPIO-enhanced MRI in the detection of malignant liver lesions

The aim of this study was to evaluate the efficacy of superparamagnetic iron oxide (SPIO)-enhanced magnetic resonance imaging (MRI) in the detection of malignant liver tumors. MRI, using fast spin-echo T-2-weighted and gradient-echo T-1-weighted imagings before and after SPIO infusion, was performed in 32 patients with known or suspected hepatic lesions. Statistical analysis was performed using lesion-by-lesion analysis. SPIO-enhanced T-2-weighted MRI showed results comparable to those of unenhanced T-2-weighted MRI in the detection of focal liver lesions. (C) 2006 Elsevier Inc. All rights reserved
