Cerebral Venous Thrombosis Mimicking a Discrete Brain Mass: A Case Report and Literature Review

Figure 4

On day 16, corresponding axial T1 precontrast (a) and postcontrast image (b) does not demonstrate rim enhancement or a fluid cavity to suggest an abscess. Additionally, except for some thin patchy postcontrast enhancement in the region of the vasogenic edema (which could represent some venous engorgement secondary to mass effect), no mass-like postcontrast enhancement is noted to suggest an enhancing tumor. (c) Corresponding susceptibility-weighted image demonstrates ill-defined areas of hemosiderin deposition in the left frontoparietal region representing areas of hemorrhage.
