The superficial lobe of the left parotid gland shows multiple, well-defined, homogeneously hypoechoic, solid nodules which are mainly present in the anterior part of the gland and in parenchyma around the parotid duct. The largest lesion measures about 21 x 18 x 17 mm. It shows posterior acoustic enhancement and a few flow signals. There is no necrosis/ calcification in any of the lesion.

Case Discussion

An elderly lady presented with left parotid region painless swelling for the last many years. Ultrasound shows numerous lesions in the superficial lobe of the left parotid gland. She had two surgeries in the parotid region during her young age. Ultrasound findings with clinical background favored a possibility of the recurrent pleomorphic adenoma of the parotid gland.

Intra-operative frozen section of the largest lesion revealed pleomorphic adenoma. Total parotidectomy was performed.
