Case in brief
A 62-year-old man with newly diagnosed prostate adenocarcinoma underwent staging with 99mTc-PSMA and 99mTc-MDP scans. The bone scan indicated tracer activity near the left kidney, which was further evaluated with 99mTc-PSMA SPECT/CT, revealing a fluid density collection in the left perinephric space. Contrast-enhanced CT confirmed the diagnosis of urinoma, highlighting the need for careful interpretation of imaging findings.
What made this case unusual
The case is notable for the detection of a large urinoma associated with 99mTc-PSMA activity, which is an atypical finding in prostate cancer staging.
Diagnostic / clinical pearl
Clinicians should be aware that atypical patterns of 99mTc-PSMA uptake may indicate underlying conditions such as urinoma, which can affect patient management.
Why it matters
Recognizing these atypical imaging findings can prevent misinterpretation and ensure timely and appropriate interventions for patients with prostate cancer.
