50-year-old male patient with histologically proven ACC of the left lacrimal gland. Axial NECT of the orbits shows a well-circumscribed, slightly hyperdense mass (arrow) involving the left lacrimal gland. There is suggestion of minimal adjacent bony scalloping. b. Coronal contrast-enhanced FS TIW image of the same patient shows avid, homogeneous, contrast enhancement within the mass (asterisk), mimicking a cavernous hemangioma. There is thinning of the overlying left frontal bone (arrow). c. Axial T2W image of the same patient showing intermediate signal within the mass (asterisk) suggesting high cellularity, a feature that is uncommon in hemangioma. The patient underwent surgery, which revealed ACC with multiple areas of microscopic perineural spread not detected by imaging. d. Contrast-enhanced axial T1W image obtained in a different patient 10Â years after surgery of an ACC of the left lacrimal gland shows macroscopic perineural tumour recurrence along the supraorbital nerve (arrows). The findings were confirmed histologically
