Figure 3: Temporal evolution of hematoma and edema after day 1 (a, b, and c), day 3 (d, e, and f), and day 10 (g, h, and i). On T1-weighted images, the hyperintense hematoma on day 1 (a) gradually changes to a hyperintense core over 10 days (c). On T2-weighted images, the core of the hematoma becomes hyperintense within 3 days (e) and develops a hypointense ring on day 10 (h) representing cavitation. The latter could also be discerned on T2*-weighted images on day 10 (i).
