Rectal ameboma: A new entity in the differential diagnosis of rectal cancer

Figure 2 Contrast-enhanced pelvic magnetic resonance images of a 46-year-old female patient. A: Increased wall thickness in sagittal sections on T2-weighted magnetic resonance imaging, almost causing obstruction of the rectal wall (orange circle); B: Heterogeneity in mesocolic adipose tissue (white arrow) and asymmetric significant wall thickening in the rectum (orange asterisk) on T2-weighted axial magnetic resonance imaging; C: Lymph nodes in the perirectal region on diffusion weighted imaging (yellow arrow); D: T1-weighted axial post-contrast magnetic resonance images showing homogeneous contrast enhancement in the rectum with increased wall thickness (orange asterisk) and heterogeneity in mesorectal adipose tissue (white arrow).
