Diffusion and magnetization transfer imaging was performed on 29 children with encephalopathy and 69 children in the normal control group. Neurofibromatosis lesions had significantly lower magnetization transfer ratios and lower apparent diffusion coefficients than normal. Apparent diffusion coefficients of leukodystrophy, hypoxic/ischemic encephalopathy, and post-infectious encephalopathy were significantly higher than normal. Two radiologists independently detected more lesions and scored higher lesion contrast on T2- and FLAIR-weighted images than diffusion and magnetization transfer imaging. In conclusion, apparent diffusion coefficient and magnetization transfer ratio determination is not more sensitive than T2- and FLAIR-weighted imaging in assessing children with encephalopathy.

We present a case of pulmonary metastasis from pancreatic cancer with biphasic radiological patterns: demarcated nodules, irregularly shaped opacities showing the so-called ‘air-space pattern’, and both typical and atypical radiological findings. The histology of the demarcated nodules was poorly differentiated adenocarcinoma identical to the pancreatic tumor, while that of the irregularly shaped opacities was well-differentiated adenocarcinoma showing a lepidic growth pattern. Pulmonary metastasis from pancreatic cancer may contain components of various differentiations showing different radiological findings.

To determine the ability of CT colonography to detect and characterize the normal appendix in adults. A total of 55 patients with CT colonography examinations are analyzed. Each observer detected an appendix in 48 cases (87%), with high interobserver concordance (kappa=0.679). The appendiceal diameter varied from 3 to 12 mm (mean 6.2 mm) with wall thickness uniformly 1 mm or less. Gas filled at least part of the appendiceal lumen in 37 cases (67%), more frequently in the prone position. Appendicoliths and periappendiceal stranding were seen in 2 and 1% of cases, respectively. An appendix can be reliably identified in approximately 87% of normal adults using CO2-insufflation CT colonography.

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.

We report a case of gallbladder perforation with contained pericholecystic abscess, diagnosed by MRCP. MRCP demonstrated direct communication between the gallbladder lumen and a pericholecystic abscess, with associated cholelithiasis. MRCP can be helpful in diagnosis of clinically silent gallbladder perforation in patients with right upper quadrant pain.

MRI was more sensitive than US or CT for determining the retroperitoneal origin, and for orienting tumor histology and reducing the differential diagnosis with other retroperitoneal tumors.
