DIFFUSE CONTRAST ENHANCEMENT ON MR IMAGES IN BRAIN INFARCTION: "PSEUDOTUMOR SIGN"

Original Research
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.
Infarction. pseudotumor,. diffuse enhancement.
