[Color Doppler echography in the diagnosis of nonspecific granulomatous prostatis: personal experience].
Non-specific granulomatous prostatitis (NSGP) is a rare but important pathology of the prostate because it often is confused with prostatic cancer. In fact, NSGP, presents at digital rectal examination as an area of increased consistency and painful, and at endorectal ultrasonography as an hypoechoic area with inhomogeneous echo structure. The frequent elevation of Prostatic-Specific Antigen (PSA) serum level vanish, moreover, its role of a differential factor. Since 1994 we used Echo-color doppler (ECD) in the evaluation of prostate cancer with satisfying results. The aim of our work is to value the route of ECD in the diagnosis of NSGP, and in the differential diagnosis with prostate cancer, actually only bioptic . Since January 1994 we observed 9 cases of NSGP; 7 patients with prostatic symptomatology and 2 with PSA serum level between 4 and 10 ng/ml. In all patients we performed endorectal US who showed, in 7 cases, nodular hypoechoic areas in the peripheral or central zone of the prostate, and in 2 cases the presence of evident BPH. In 5/7 cases with hypoechoic areas, ECD-US showed an increase of color intensity intra-perinodular. In 2 patients with BPH no marked color enhancement was observed. The diagnosis of NSGP has been done after needle biopsy in the 7 patients with suspect nodular areas, and in the 2 patients with BPH, after histological examination secondary to open prostatectomy. Our experience shows that ECD-US scanning picture in NSGP is superimposable with the prostatic cancer one. In fact the anatomical presupposition on the grounds of the "positivity" in ECD-US, focal hypervascularization, is present in ECD scanning pictures of both pathologies. In conclusion, ECD doesn't give an advantage in the differential diagnosis between NSGP and prostate cancer that actually remains only bioptic .
