"The principal differential is a cholesterol granuloma, which can appear similar on CT, however, MRI is the main imaging modality in differentiating the two apart. A mucocele is low/intermediate on T1 imaging and a cholesterol granuloma is hyperintense on T1."
"T1: low to intermediate signal"
"T2: high signal"
"T1+ Gd: no central enhancement; may have peripheral enhancement; favoured to be due to adjacent secondary inflammatory response 1"
"DWI/ADC: no abnormal diffusion restriction"
Expected headings
"Clinical presentation"
"T1+ Gd: no central enhancement; may have peripheral enhancement; favoured to be due to adjacent secondary inflammatory response 1"
"T1+ Gd: no central enhancement; may have peripheral enhancement; favoured to be due to adjacent secondary inflammatory response 1"
"The management can vary; serial imaging to assess for change or surgical drainage can be performed 2."
