April 10, 2026

A Rare Case of Metastatic Prostate Cancer to the External Auditory Canal Evaluated with 18 F-Piflufolastat PET/CT.

Key Points

To describe a rare case of metastatic prostate cancer affecting the external auditory canal and its evaluation methods.
Case report describing patient evaluation
Utilization of prostate-specific membrane antigen PET/CT imaging
Analysis of atypical metastatic localization
Identification of metastatic prostate cancer in the left external auditory canal
First reported case of such localization evaluated with PSMA PET/CT
Emphasis on the need for awareness in misdiagnosis of atypical metastasis

Abstract

Atypical metastatic spread to the external auditory canal (EAC) from prostate cancer is a very rare condition. To the best of our knowledge, this is the first case reporting a prostate cancer patient with a metastasis in the left EAC evaluated with prostate-specific membrane antigen-positron emission tomography/computed tomography. Nuclear medicine physicians should be aware of this atypical metastatic localisation that can be misdiagnosed.
