CRP and hematoma: However, the progression of IMHB is unpredictable, ranging from complete resolution to abrupt rupture (15, 21), although numerous predictors of IMHB evolution, such as maximum aortic diameter (≥4.0 cm) (19), hematoma thickness (≥10 mm) (20), ULP development (22) and an elevated CRP level (7.2 mg/dl) (23), have been summarized.
