Figure 4 (Case 12). — A 46-year-old man presented with progressive obstructive voiding symptoms, perineal pain, constipation, and repeated episodes of gross hematuria for the past 5 months. Pathological examination of the prostate needle biopsy indicated leiomysarcoma confirmed with immunohistochemical staining. (A) Digital subtraction angiography (DSA) of the left internal iliac artery shows a large hypervascular mass (asterisk) supplied from the left prostatic artery (white straight arrow); (B) Angiography of the left prostatic artery (white straight arrow) shows the massive neovascularization in the tumor (asterisks). Noted the indwelling catheter in the compressed bladder (white arrowhead); (C) Coronal contrast-enhanced T1-weighted magnetic resonance image (MRI) obtained before transcatheter arterial chemoembolization (TACE) shows a large heterogeneous hypervascular tumor arising from the prostate gland (asterisks); and (D) Coronal contrast-enhanced T1-weighted MRI obtained at 10 months after three sessions of TACE shows almost complete necrosis of the prostatic tumor (asterisks) and significant reduction of the tumor volume. The patient refused other treatments and he is alive asymptomatic with focal residual contrast enhanced lesion, during 30 months of follow-up.
