ABSTRACT
Objective To analyze multislice CT (MSCT) multiphase multiphase enhancement scanning in the atypical hemangiomas. Methods During February 2013 from January 2014, chosing125 cases of patients with atypical hemangiomas in our hospital were retrospectively analyzed. Results There was a total of 240 lesions in 125 patients, multiple (2 or higher) in a total of 70 cases, 55 cases of single. A total of 170 were located in the right lobe, 70 were located in the left lobe, lesions was 0.8 to 4.5 cm in diameter, the average was (2.53±0.21) cm. A total of 205 lesions were circular, a total of 35 as lobulated or irregular. CT scan, a total of 155 were low density, 85 in equal density. A total of 120 state clearly, realm for part of the fuzzy and parts out of a total of 35, 85 was fuzzy. A total of 45 lesions density uneven, a total of 195 was lesions density uniformity. In 240 intrahepatic lesions, a total of 145 lesions present performance1, 80 lesions belong to 2 kinds of forms, 15 lesions characterized by 3 kinds of forms. Conclusion Although a few hemangiomas reinforcement is not typical, by the mutiperiodic enhanced MSCT scanning remain their respective characteristics, in identification of its pathological changes has important diagnostic value.
ABSTRACT
Objective To assess the characteristics of magnetic resonance imaging (MRI) for spinal cavernous angiomas.Methods The examinations of plain scan and contrast enhanced scan of magnetic resonance (MR) were performed in three patients with spinal cavernous angiomas.Results The focus of two cases was located in thorax segment of the spinal cord and one in lower cervical segment.All focuses were single and the shape of spinal cord was normal or slightly thick. MRI characteristic of spinal cavernous angiomas was just like popcorn or mulberry with a jumbled gobbet signal. Low and short T2 signal appeared around the focus. In all cases, there were no obvious contrast enhanced signal in 2 cases and one case with moderate contrast enhanced signal. The diameter of hemorrhage was smaller than that of the spinal cord.Conclusion MRI has higher sensitivity and specificity in the diagnosis of spinal cavernous angioma.
