Plug inguinal hernia repair mimicking nodal spread of prostate cancer on PSMA-PET/CT

A variety of non-prostatic or non-malignant findings exhibiting prostate specific membrane antigen (PSMA) tracer uptake and resemble metastatic disease on positron emission tomography (PET) imaging. In this case, a 72-year-old man presenting for initial staging of prostate cancer was found to have P...

Sumario:A variety of non-prostatic or non-malignant findings exhibiting prostate specific membrane antigen (PSMA) tracer uptake and resemble metastatic disease on positron emission tomography (PET) imaging. In this case, a 72-year-old man presenting for initial staging of prostate cancer was found to have PSMA tracer uptake along the left external iliac vessels corresponding to a structure resembling a lymph node on computed tomography (CT). This finding was initially concerning for nodal spread of the patient's primary neoplasm. However, chart review revealed a remote history of left inguinal hernia plug repair with location corresponding to the area of PSMA activity. This case highlights PSMA uptake related to surgical mesh from inguinal hernia plug repair as a mimic of nodal metastatic disease on PSMA PET.
