case_images: A 50-year-old female was referred to our institution with 3 months of left hyperglobus and paresthesias in the distribution of V2, for CT and MRI imaging concerning for mass of the left maxillary sinus with tumor visible along orbital floor with bony defect to the inferolateral orbit (shown in Fig. 1, 2). Three years later, the patient re-presented with recurrent left hyperglobus (shown in Fig. 1).
case_images: Imaging at original presentation. a T2 MRI orbits with abnormal enhancing tissue that is T2 hypointense with restricted diffusion in the left maxilla and left maxillary sinus, consistent with neoplasm. b Maxillofacial CT scan demonstrates soft tissue density extending into the left maxillary sinus and correlates with enhancing tissue seen on MRI. There is associated multifocal thinning and erosion of the posterior and lateral walls of the left maxillary sinus, inferolateral left orbit, and involvement of skull base foramina without intraorbital or intracranial extension.

case_images: Imaging at time of recurrence. T1 (a) and T2 (b) MRI orbits with and without contrast demonstrating enhancement along the left orbital floor and superolateral maxillary sinus reconstruction bed. There is superior displacement of the inferior rectus, left frontal sinus opacification, and no proptosis. c CT maxillofacial demonstrating slight interval increase in soft tissue along the left orbital floor in the postsurgical bed, corresponding to a new area of signal abnormality on MRI.

case_images: MRI orbits demonstrated a new signal abnormality along the left orbital floor suspicious for recurrence, and maxillofacial CT demonstrated a slight interval increase in soft tissue mass in the left orbital floor corresponding to the area of new signal abnormality on MRI (shown in Fig. 3).
case_images: PET scan at time of recurrence. a FDG uptake within the postsurgical bed at the left orbital floor, concerning for recurrence of ameloblastoma. b FDG uptake in the left lower lobe pulmonary nodule posterior to the aorta, suspicious for metastatic disease.

case_images: Whole-body PET demonstrated local recurrence in the left orbital floor as well as FDG-avid cervical nodes and pulmonary nodules suspicious for metastatic disease (shown in Fig. 4).
