Accessory parotid glands are a common clinical occurrence and usually drain into the main Stenson's duct by small ductules and thereby, into the buccal cavity. Presence of an accessory parotid gland with an ectopic fistulous duct is a rare occurrence. We present the imaging findings in a case of right accessory parotid gland with ectopic fistulous duct associated with bilateral pre-aural append...
Lipoma rarely involves parotid gland especially in children. An 11-year-old boy presented with right parotid swelling. Preoperative workup including CT scan and FNAC gave suspicion of parotid gland lipoma. The diagnosis was confirmed on histopathology after complete excision of the mass.
Blunt trauma to the parotid gland is extremely rare and requires considerable force. We present a unique case in which a child sustained parotid injury without any associated injury to the facial skeleton, parotid gland and ductal structures and managed successfully. A literature search revealed that this type of injury has not been reported previously.
Immunohistological expressions of the cytokeratin (CK) subclass, vimentin, glial fibral antigen protein (GFAP), alpha-smooth muscle actin, and S-100 protein were investigated in pleomorphic adenoma of the parotid gland. In addition, the correlation between immunohistological findings in the normal parotid gland and those in pleomorphic adenoma was examined. Vimentin, S-100 protein, and GFAP, wh...
Xerostomia (dry mouth), resulting from radiation damage to the parotid glands, is one of the most common and distressing side effects of head-and-neck cancer radiotherapy. Recent MRI studies have demonstrated that the volume reduction of parotid glands is an important indicator for radiation damage and xerostomia. In the clinic, parotid-volume evaluation is exclusively based on physicians' manu...
Congenital absence or rudiment major salivary glands, especially of the parotid glands, are a rare entity. Aplasia of parotid glands has been described alone or in association with abnormalities of other salivary glands, first branchial arch developmental disturbances and other congenital anomalies such as lacrimoauriculodentodigital syndrome, mandibulofacial dysostosis and ectodermal dysplasia...
Long lasting sialolithiasis can cause structural and functional changes of the salivary glands, inflammatory infiltration and fibrosis. However fat infiltration with sialolithiasis has not been described in the parotid glands. We describe a 60 years old man, bus-driver who presented with a history of reccurent right parotid sialadenitis and was diagnosed to have bilateral sialolithiasis and lef...
INTRODUCTION Radiotherapy of nasopharyngeal carcinoma patients with parapharyngeal space (PPS) involvement may deliver high dose to the parotid gland. This study evaluated parotid gland changes during and up to 3 months after radiotherapy. METHODS Kilovoltage computed tomography (CT) scans of head and neck region of 39 nasopharyngeal carcinoma patients with PPS involvement were performed at p...
OBJECTIVES/HYPOTHESIS Parotid gland calcifications can be incidental findings on computed tomography (CT) and have been reported to be associated with chronic inflammatory conditions. Associations between parotid gland calcification and other common medical conditions have not been reported. METHODS Following institutional review board approval, 1,571 patients who underwent noncontrast head C...
