Adenoid cystic carcinoma of lacrimal gland
Updates to Article Attributes
Body
was changed:
Adenoid cystic carcinoma (ACC) of the lacrimal glands is an extraconal malignancy usually originating from the orbital lobe of the lacrimal gland.
Clinical presentation
It often presents with orbital pain and paresthesia, since this type of tumour is frequently associated with perineural spreading.
Radiographic features
CT-scan
CT-scan shows may show an infiltrative mass involving the lacrimal gland, very often associated with bony destruction, showing enhancement after contrast administration.
MRI
Signal characteristics include
- T1: homogeneously hypointense
- T2: usually isointense, but sometimes hypointense (basaloid subtype)
- T1 C+ (Gd): moderate enhancement
Differential diagnosis
- inflammatory mass associated with:
- lymphoid hyperplasia of the sinus glands
- non-Hodgkin lymphoma
- other neoplasm: pleomorphic adenoma (benign), squamous cell carcinoma, mucoepidermoid carcinoma
