Imaging findings of inflammatory pseudotumor-like follicular dendritic cell tumors of the liver: Two case reports and literature review

Table 1 Computed tomography and magnetic resonance imaging findings of inflammatory pseudotumor-like follicular dendritic cell tumors

Scan type	Case number	Number of lesions	No-contrast	Arterial phase	Portal venous phase	Equilibrium phase	Hepatobiliary phase	Dynamic enhancement pattern
MRI	1	2	Well-defined, hypointense on T1WI, hyperintense on T2WI	Hypoenhance-ment	Hypoenhance-ment	Hypoenhance-ment	Patchy hyperintense signal	Heterogeneous sustained enhancement
CT	1	2	Well-defined hypodensity	Isoenhance-ment	Hypoenhance-ment, reach the peak value	Hypoenhance-ment		Heterogeneous sustained enhancement
	2	1	Huge ill-defined heterogeneous hypodensity	Hypoenhance-ment, many distorted blood vessels	Hypoenhance-ment, reach the peak value	Hypoenhance-ment		Heterogeneous sustained enhancement

CT: Computed tomography; MRI: Magnetic resonance imaging; WI: Weighted imaging.
