Invasive squamous cell carcinoma of the supraciliary ridge treated with chemoradiation. There are post-treatment findings in the left supraciliary region. There is a persistent mild patchy, ill-defined enhancement in the left supra-orbital subcutaneous tissues with extension into the left orbital roof, traversing the frontal bone along the lateral aspect of the left frontal sinus with slight epidural extension, and extraconal left orbital extension. The right orbit is unremarkable. There is a small left maxillary sinus retention cyst.
