“…In a retrospective study of 34 Warthin tumors, 94% of these tumors had greater uptake than normal parotid gland tissue on Tc-99m scintigraphy after lemon juice stimulation [9]. On CT scans, Warthin tumors appear as well-delineated lesions commonly involving the inferior pole of the gland; the presence of bilateral or multiple lesions is suggestive, but not diagnostic of Warthin tumor [10]. A validation study showed that gadolinium-enhanced dynamic MRI has been found to have a 100% sensitivity and an 80% specificity in differentiating malignant salivary tumors from benign tumors [11].…”

“…Most patients present with a solitary, painless mass in the peri-parotid area. Radiologic evaluation, whether it be with ultrasound, CT scans, or MRI, reveal well-demarcated, heterogeneous lesions [8,10,11]. A definitive diagnosis is usually rendered when FNA reveals monolayered sheets of oncocytic cells, lymphocytes, and amorphous, cystic debris [13].…”

Background: Warthin tumor is the second most common benign salivary tumor. This case highlights a patient who underwent local excision of a solitary Warthin tumor from the peri-parotid area. He subsequently presented with recurrent, multi-centric disease with bilateral parotid and cervical lymph node involvement. Case Report: A 45 year old, tobacco-using male was referred for a right head and neck mass. Exam revealed a mobile, painless mass near the angle of the jaw.Nasofibroscopic exam revealed a non-obstructive nasopharyngeal mass. CT confirmed an ovoid mass inferior to the right parotid gland. Fine-needle aspiration (FNA) was non-diagnostic. Deep biopsies and local excision of the right neck mass were performed. Nasopharyngeal biopsies were negative; the neck mass was consistent with Warthin tumor. The patient returned approximately 4 years later with a right pre-auricular mass and right upper neck lymphadenopathy. Diagnostic work-up, including ultrasound-guided FNA, revealed bilateral parotid gland Warthin tumor. The patient was symptomatic from the right-sided disease and not the left. Consequently, he elected right parotidectomy and excision of the right upper neck lymph nodes and clinical follow-up of the left mass. Upon pathologic review, there was Warthin tumor present in the parotidectomy and right lymph node specimens.

“…18,19 CT helps in identifying the structure, margins, number of lesions, pattern of enhancement, washout timeframes, and attenuation coefficients to differentiate between various parotid lesions. 3 On CT and MRI, Warthin's tumour typically appears wellcircumscribed with homogeneous, cystic, or solid lesions in the parotid or periparotid region, most commonly involving the inferior pole of the gland. The appearance of multiple or bilateral parotid or periparotid masses is suggestive of a Warthin's tumour.…”

“…A study by Choi et al 23 found that Warthin's tumour (8 out of 9) showed strong early phase enhancement with a decrease in attenuation on delayed imaging (120 seconds) as opposed to the signs for pleomorphic adenoma (30 out of 35) which showed increased delayed enhancement. 3 A 30% washout ratio threshold can be useful for predicting whether parotid gland tumours are benign or malignant. Warthin's tumours typically demonstrate ≥30% washout, whereas malignant tumours demonstrate low washout of <30% and complicated cysts show early enhancement and low washout ratio (≤30%).…”

“…The tumour usually occurs in older patients, most often in the sixth and seventh decades of life. 3 There are several hypotheses concerning Warthin's tumour, but the widely accepted explanation describes it as a condition that develops from the hyperplasia of the salivary duct cells isolated in the lymph node of the parotid gland during embryogenesis. Other theories suggest that Warthin's tumour is caused by the infiltration of lymphocytes inside an existing adenoma or interaction of hyperplasia of glandular epithelium and excessive lymphoid tissue inside the stroma.…”

Objective: To characterise the computed tomography / magnetic resonance imaging (CT/MRI) features to diagnose adenolymphoma (Warthin's tumour). Methods: Between February 2008 and December 2012, CT/MRI scans of consecutive patients referred for suspected parotid tumours were performed before surgery or fine-needle aspiration cytology. All patients underwent surgery and samples were sent for pathological confirmation of the diagnosis. Their CT/MRI scans with pathologically proven Warthin's tumours were reviewed. Results: All of the 17 patients in the study were men, and aged between 43 and 86 years (mean, 65 years). All the patients initially presented with gradually increasing painless masses, with duration of symptoms ranging from 1 month to 120 months (mean, 61 months). Two patients were found to have bilateral Warthin's tumour, nine had a left-sided Warthin's tumour, and six had a right-sided Warthin's tumour. Conclusion: The CT/MRI findings were helpful in distinguishing these benign lesions from other parotid gland tumours when biopsy results are non-diagnostic. Further studies are needed to assess the positive predictive value of the imaging features.
