Left orbit/sinus solitary fibrous tumor status post subtotal resection twice. There is no significant interval change in size of the mass centered within the left orbit with extension into the adjacent paranasal sinuses, premaxillary space, and masticator space. Overall, the tumor measures approximately 45 mm in width, 50 mm in height, and 40 mm in length. There is marked left proptosis and compression of the optic nerves and most of the extraocular muscles, with relative sparing of the superior rectus. There are postoperative findings in the left maxillary sinus, with moderate mucosal thickening and new secretions. The right orbit is unremarkable. There is no evidence of intracranial extension of tumor.
1. No appreciable change in size of the solitary fibrous tumor involving the left orbit with extension into the adjacent paranasal sinuses, premaxillary space, and masticator space. 2. Findings suggestive of acute sinusitis.
