عنوان انگلیسی DIFFUSE CONTRAST ENHANCEMENT ON MR IMAGES IN BRAIN INFARCTION: "PSEUDOTUMOR SIGN"
چکیده انگلیسی مقاله The purpose of this study was to describe the pattern of diffuse enhancement seen on contrast-enhanced MR images in patients with subacute infarction. A retrospective study of 104 patients with the diagnosis of stroke who had undergone contrast-enhanced MR scanning within2 weeks of the inciting neurological event revealed 66 patients who demonstrated different patterns of contrast-enhancement in the region of infarction. Diffuse enhancement was seen in the cerebellum and occipital regions in 12 patients. As this diffuse enhancement could be confused with enhancement seen in primary or metastatic tumors of the brain, the term "pseudotumor sign" was used for this type of enhancement. We concluded that subacute infarct should be included in the differential diagnosis of tumors when this imaging pattern is observed.
