Prostate cancer (PCa) is a multifaceted, heterogeneous disease (with 7 molecular subtypes), which can metastasize to common sites, such as bone, lymph nodes, liver, and lungs. However, with PSMA PET imaging, rare sites of metastasis are increasingly discovered. We report 5 cases of unusual metastases in patients with castrate-sensitive PCa: solitary right inguinal nodal metastasis, solitary abdominal wall metastasis, penile shaft metastases, solitary perineum metastasis, and pleural metastases. These cases further support the use of PSMA-PET imaging in PCa monitoring, with the ability to detect solitary, small volume, and rare sites of metastases, which may not be apparent on conventional imaging.
