<jats:title>Abstract</jats:title>
<jats:p>A 64-year-old man with metastatic castration-resistant prostate cancer presented for prostate-specific membrane antigen (PSMA) PET/CT in preparation for <jats:sup>177</jats:sup>Lu-PSMA radioligand therapy. For precedent <jats:italic toggle="yes">BRCA</jats:italic> mutation assessment, fine-needle aspiration cytology of 2 PSMA-positive lymph node metastases was conducted. The acquired material was suitable for next-generation sequencing-based gene panel diagnostics and did not show a <jats:italic toggle="yes">BRCA1</jats:italic>/<jats:italic toggle="yes">2</jats:italic> mutation, thus PSMA radioligand therapy was initiated. Fine-needle aspiration cytology of lymph node metastases may be a viable option in evaluating further therapeutic alternatives.</jats:p>
