[Show abstract][Hide abstract]ABSTRACT: To highlight the computed tomography (CT) and magnetic resonance imaging (MRI) characteristics of lacrimal gland adenoid cystic carcinoma.
We reviewed the clinical records and imaging findings of 17 patients who were histopathologically diagnosed with primary adenoid cystic carcinoma of the lacrimal gland between August 1998 and November 2010. Orbital CT scans were performed in 17 patients and MRI scans were obtained in 13 patients.
On the CT scans, out of 4 cases of adenoid cystic carcinoma, 3 showed characteristic features of a soft tissue mass with poorly enhancing areas representing cystic changes, and 4 of 17 cases had contiguous bony erosion. On the MRI scans, all cases had mixed signal intensity on T2-weighted images, and 6 cases showed poorly enhancing areas.
Enhanced CT and MRI (including T2-weighted) are helpful in the diagnosis of primary adenoid cystic carcinoma of the lacrimal gland.
