Adenoid cystic carcinoma of lacrimal glands

Adenoid cystic carcinoma (ACC) of the lacrimal glands is an extraconal malignancy usually originating from the orbital lobe of the lacrimal gland.

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
