Incidental Finding of Acute Lymphocytic Leukemia in a Prostate-Specific Membrane Antigen PET/CTAcksteiner, Christian Dr Med, FRANZCR; Sounness, Brett MBBS, FRANZCRClinical Nuclear Medicine: September 2019 - Volume 44 - Issue 9 - p e529–e531 doi: 10.1097/RLU.0000000000002712 Interesting Images Buy Abstract Author InformationAuthors Article MetricsMetrics PSMA PET/CT is known to show uptake in various benign and malignant processes. The following PSMA PET/CT was performed for prostate carcinoma staging (Gleason 3 + 4 left apex; PSA 5.8). It shows incidental diffuse PSMA marrow uptake, not typical for prostate metastatic disease. No treatment had been commenced at the time of the scan. Serology and bone marrow biopsy showed B-cell acute lymphocytic leukemia. Focal PSMA uptake in the right ischium was correlated with a T1 hypointense lesion on a previous MRI and was convincing for a skeletal metastasis. Alternative diagnoses in diffuse skeletal PSMA uptake need therefore to be considered. From the South Coast Radiology, Varsity Lakes, Queensland, Australia.
