Abstract

We present a 68-year-old man with newly diagnosed high-risk prostate cancer who was referred for PSMA PET/CT after the initial CT showed a contrast-enhanced structure resembling a lymph node in the left inguinal canal. No other findings suggesting metastatic disease were seen on CT or bone scintigraphy. PSMA PET/CT showed moderate PSMA uptake in the inguinal tissue, substantiating an unexpected location of lymph node metastasis. The uncommon location warranted an excision biopsy, and an IV pyogenic granuloma was diagnosed on histological examination, emphasizing the importance of biopsy of unexpected findings.
