We describe a rare presentation of a symptomatic parathyroid adenoma located in an ectopic retropharyngeal position in a 13-year-old boy. Preoperative CT scan and MRI demonstrated the ectopic location of the parathyroid adenoma. The patient underwent successful parathyroidectomy with cure of his hyperparathyroidism. On pathologic exam, the specimen was made up of a parathyroid adenoma and adjacent thymic tissue, indicating that it was likely an undescended lower parathyroid gland arising from the third pharyngeal pouch. Ectopic retropharyngeal parathyroid adenomas are very rare and to our knowledge, none have been previously described in adolescents.

More Than Just Cerumen: Lesions of the External Auditory Canal and Their Surgical Implications

Neurographics (2020)

M.R. Shroads Peter B. Manning Mahmood F. Mafee Julie Bykowski

There is an extensive differential diagnosis for lesions of the external auditory canal, including congenital, benign, locally aggressive, and malignant processes. Although external auditory canal lesions are commonly identified clinically, imaging is helpful to determine if the process is isolated to the external auditory canal or to evaluate the extent of involvement of adjacent structures. Because staging of external auditory canal malignancy is based on the location and extent of tumor rather than the cell type, multimodality imaging is often necessary for surgical planning. This article reviews defining clinical and imaging features of external auditory canal lesions, presents an organized approach to their characterization on CT and MR imaging, and discusses their surgical implications.Learning Objective: To review the differential diagnosis of external auditory canal lesions and recognize their key imaging and clinical features, including surgical implications.
