Radiology Quiz Case 1

Radiology Quiz Case 1 A 25-year-old woman presented with a 2-month history of a gradual increase in right facial swelling and mild, generalized pain in her right cheek. Physical examination revealed a nontender, soft, freely mobile, 4-cm mass in the region of the right parotid gland, with no overlying erythema or associated cervical adenopathy. A contrast-enhanced computed tomogram revealed diffuse enlargement of the right masseter muscle, with asymmetrical internal enhancement and no involvement of underlying bone. The parotid, submandibular, and sublingual glands appeared normal (Figure 1). View LargeDownload Figure 1. An in-office ultrasonogram revealed an encapsulated mass with increased internal vascular flow. Auscultation demonstrated a bruit. Magnetic resonance imaging with contrast showed significant enlargement of the right masseter muscle, with homogeneous enhancement as well as diffuse hyperintensity in the affected region of muscle, likely representing edema. Multiple flow voids were seen on T2 sequences within the region of enhancement. There was no evidence of inflammatory changes within the adjacent tissue (Figure 2). View LargeDownload Figure 2. Angiography of the neck showed increased vasculature over the right masseter muscle, as compared with the left, as well as asymmetry in the size of and flow in the right retromandibular vein and branches of the external carotid artery (Figure 3). The patient underwent a transoral excision of the mass. View LargeDownload Figure 3.
