Periorbital fillers are widely used as a minimally-invasive method of soft-tissue augmentation, though have been associated with serious complications including infection, foreign-body granuloma and filler migration. Such complications are often challenging to distinguish from other diseases of the periorbital region and are frequently missed on clinical examination. Hyaluronic acid fillers have distinctive morphology and signal characteristics on imaging, typically demonstrating low T1 and high T2 signal intensity with distinct, serpiginous borders. Thus, familiarity with the typical imaging features of these fillers and their associated complications may be useful to prevent diagnostic confusion and delay. We describe the clinical and MRI findings in three patients with periorbital hyaluronic acid filler injections.
