It often presents with orbital pain and paresthesia, since this type of tumor is frequently associated with perineural spreading.
CT may show an infiltrative mass involving the lacrimal gland, very often associated with bony destruction, showing enhancement after contrast administration.
Signal characteristics include:
- T1: homogeneously hypointense
- T2: usually isointense, but sometimes hypointense (basaloid subtype)
- T1 C+ (Gd): moderate enhancement
- inflammatory mass associated with
- lymphoid hyperplasia of the sinus glands
- non-Hodgkin lymphoma
- other neoplasms: pleomorphic adenoma (benign), squamous cell carcinoma, mucoepidermoid carcinoma
