A 50-year-old man with adenocarcinoma of the left lacrimal sac and nasolacrimal duct. A 50-year-old man with adenocarcinoma of the left lacrimal sac and nasolacrimal duct. A, Postcontrast thin-section coronal CT reformatted images demonstrate tumor in the lacrimal sac and duct (white arrow) with direct extension into the inferior intraconal orbital space (black arrow). B, Due to the extent of tumor spread, the patient underwent left orbital exenteration, maxillectomy, and free flap reconstruction (white arrowheads) with adjuvant radiation therapy and has been disease-free for 3 years.
