MRI is widely used in diagnosis in nasal cavity and sinuses lesions due to superior soft-tissue resolution and multiplanar capabilities.[1] These lesions cannot be distinguished based solely on their typical signs or features.The CCP is not specific to IP; although some studies reported up to 80% of the cases, [2] it is also present in malignant masses, such as non-Hodgkin’s lymphoma (NHL), squamous cell carcinoma, esthesioneuroblastoma, and adenocarcinoma. [3,4] Some authors show a low frequency of rhinosinusitis with nasal polyps mimicking the CCP pattern. Nasal polyps can arise from chronic inflammation or allergies, and often lead to nasal obstruction and other symptoms.  Sometimes they create an appearance reminiscent of a cerebriform pattern, characterized by a series of undulating layers.[5] In small and abundant edematous stroma band lesions, the CCP pattern cannot be detected. [1] Other studies show septal enhancement, and it could associated with a fibrous band presence, being similar to CCP on T1W C+. [1] Among atypical features in those lesions, studies demonstrated that ADC values were the most valuable metric for differentiation, [1,6] including types of sclerosis in computerized tomography, presence of central necrosis, intracranial extension, and enhancement pattern.[1,2,6]
