Spontaneous infarction of Warthin's tumor: imaging findings simulating malignancy.

The authors present a rare case of spontaneous infarcted Warthin's tumor of the parotid gland mimicking malignancies. CT and MR images demonstrated the presence of extensive necrosis and rim enhancement with ill-demarcated margins. Although the differentiation of infarcted Warthin's tumors and primary salivary gland malignancies is challenging, radiologists should recognize this uncommon pathological condition.
