On MRI, these cysts typically exhibit high SI on T2-WI and variable SI on T1-WI, depending on the presence of mucin, proteinaceous material, or haemorrhage within the cyst (figure although typically benign, cysts are frequently managed with surgical excision, even in asymptomatic cases, due to the potential risk of complications, such as infection or inflammation, which may result in cyst wall fibrosis and degradation of the epithelial lining [76].
