Primary mucosal-associated lymphoid tissue extranodal marginal zone lymphoma of the bladder from an imaging perspective: A case report

Table 2 Comparison of image findings among the present case, previously reported cases, typical bladder carcinoma and typical glandular cystitis

	US	CT	MRI
Present case	Hypoecho mass with sharp boundaries	Solitary mass with continuously enhancement and thickened bladder wall	No
Common findings of cases reported	Hypoecho mass	Solitary mass with homogeneously enhancement	Homogeneously enhancing mass with hypointensity in T1WI, intermediate intense intensity in T2WI, hyperintensity in STIR
Common findings of bladder carcinoma	Hypoechoic masses with rough boundaries	Irregular solid mass with significantly heterogeneous enhancement	Early significantly enhancing mass with iso to hyperintensity in T1WI, intermediate intensity in T2WI, hyperintensity in DWI, and decreased ADC value
Common findings of glandular cystitis	Diffuse thickening or nodular eminence of the bladder wall	Thickened bladder wall with mild enhancement	Mild enhancing thickened bladder wall with intermediate intensity on T1W, hyperintense on T2W, and slightly hyperintense on DWI
