Figure 1
Images from 18F-FDG PET/CT for the WM patient. The images show abnormal tracer uptake of the prostate (SUVmax 27.0). Abnormal focal tracer accumulations in the left pulmonary nodule, and the mediastinal, retroperitoneal, and pelvic lymph nodes are also apparent. (A) MIP; (B-D) PET; (E-G) CT; (H-J) fused PET/CT. The prostatic lesion is indicated by the arrow. MIP, maximal intensity projection; PET, positron emission tomography; CT, computed tomography; WM, Waldenstrom macroglobulinemia; SUV, standardized uptake value.

Figure 2
Prostate MRI images at 1 month after ThuVAP of the prostate. The images show locally enlarged prostate mass, measuring up to 107 mm × 104 mm × 179 mm. The rectum was obviously compressed by the mass, which led to defecation difficulty in this case. The MRI report concluded that the mass was prostate carcinoma. The final biopsy histology was DLBCL of the prostate. (A-C) T2WI shows an equal signal; (D) DWI shows restricted diffusion with b value of 800 s/mm2. (A) Axial view; (B) sagittal view; (C) coronal view; (D) DWI view. The prostatic lesion is marked by an asterisk. DWI, diffusion-weighted imaging; MRI, magnetic resonance imaging; ThuVAP, thulium vaporization; DLBCL, diffuse large B-cell lymphoma; T2WI, T2 weighted imaging.
