Thymoma mimicking a thyroid mass

Radiology. 1992 Jul;184(1):75-6. doi: 10.1148/radiology.184.1.1609105.


Two cases of ectopic cervical thymoma are presented. These cases both manifested as mass lesions at the thoracic inlet, displacing the trachea, and were originally misdiagnosed as thyroid masses. The masses had clinical features similar to those previously reported for cervical thymoma: preponderance in women, benign clinical course, and absence of myasthenic symptoms.
