Patients with the most common benign lacrimal gland tumor, pleomorphic adenoma, have an excellent prognosis, provided it is completely excised at first surgery. These lesions should not undergo incisional biopsy, requiring en bloc excision along with adjacent tissues. The other affections of the lacrimal gland may or may not include biopsy on their management. CT and MRI, together with clinical data, may suggest strongly the diagnosis of pleomorphic adenoma and help to define the best management of the patients with other affections. The purpose is to illustrate the key imaging points in the diagnosis and management of neoplastic and pseudotumoral lesions of the lacrimal glands.

This study includes CT and MRI data of patients with lacrimal gland lesions, some of them with surgical specimens and histologic data and others with clinical follow up. Pleomorphic adenoma (include figure), Carcinoma ex pleomorphic adenoma, Adenoid Cystic carcinoma ,Carcinoma, Adenocarcinoma, Idiopathic Inflammatory Pseudotumor, Lymphoproliferative lesions, Wegener granulomatosis.

CT and/ or MRI are essential in the diagnosis and management of neoplastic and pseudotumoral lesions of the lacrimal gland. Peomorphic adenoma must be recognized through clinical and imaging findings because its treatment implies on its complete resection without prior biopsy.
