Female, 22 years old, history of previous left parotidectomy, currently with left periparotid salivary fistula. Evidence of partial left parotid resection is seen. The skin of the resection bed is slightly retracted with underlying scar tissue. Imaging parameters are not adequate for assessment of fine parotid parenchymal detail. Given that limitation, no definite sialocele or other fluid collection is seen. The exact location of the reported salivary fistula cannot be determined. Mildly prominent veins are noted within the parotid glandular parenchyma.The remaining salivary glands are unremarkable. The aerodigestive mucosa is smooth and free of mass lesions. No pathologic adenopathy is identified. Bone marrow signal characteristics are within normal limits.
Findings are seen compatible with partial left parotid resection. Within the limitations of protocol technique, no clear evidence of any sialocele or other periparotid fluid collection is seen. The location of the reported salivary fistula is not accurately visualized.If further imaging is warranted clinically, the patient could return for dedicated parotid imaging at 3T and with microscopy coil sequences.
