MRI sign of nodular fasciitis: a case report

Soft tissue masses of the facial region have common clinical and radiological features resulting in varied differential diagnosis. Nodular fasciitis is a benign proliferation of fibroblasts and myofibroblasts that may be mistaken for a sarcomatous lesion because of its rapid growth. Buccal space, although an uncommon site for the lesion, can be involved by nodular fasciitis. Diagnosis is usually provided by histopathology. A case of nodular fasciitis of buccal space is reported. This case demonstrated characteristic thickening and enhancement of the adjacent fascial plane, supporting the preoperative specific diagnosis of the lesion.
