Clinical and Pathological Characteristics of Organized Hematoma
Figure 2
A 36-year-old female had a 2-month history of recurrent epistaxis. (a) Initial T1-weighted magnetic resonance image before treatment, showing a slightly low intensity in the central region of the mass (coronal view). (b) Initial T2-weighted magnetic resonance image before treatment, showing a heterogeneous mass. The central portion had high signal intensity, and the surrounding region had lower signal intensity than the central portion. The paranasal mucosa was thickened but kept its structure (axial view). (c) Initial Gd-DTPA magnetic resonance image before treatment, showing that the central portion was strongly enhanced. The surrounding region was less enhanced than the central portion. The thickened mucosa of the paranasal sinus was also strongly enhanced (axial view).
