“…Differentiation of tumor from BPH with imaging modalities such as US and MR imaging has been problematic (12,13,26,27). BPH has been described as "multiple tissue nodules that express a wide spectrum of gland density and activity .…”

“…However, signal intensity in conventional MRI of the prostate is descriptive of tissue density rather than tissue type (19,20). A number of benign pathologic conditions, such as scars, hyperplasia, and prostatitis, may mimic the signal characteristics of cancer (8,19,20). The change of tissue characteristics of welldifferentiated cancers can be subtle with regard to tissue composition, making these lesions impossible to detect on T2W images (11).…”

“…Magnetic resonance imaging (MRI) with an endorectal surface coil produces high-resolution images which resolve anatomical details of the prostate excellently. The best tumor delineation is obtained using T2 weighted (T2W) images (8). However, signal intensity in conventional MRI of the prostate is descriptive of tissue density rather than tissue type (19,20).…”

Radical prostatectomy specimens from 53 men with clinical stage A or B prostate cancer were retrospectively reviewed and compared with correlative axial T2-weighted magnetic resonance (MR) images obtained just before surgery. Non-cancerous lesions were evaluated for signal intensity and location. Focal high-signal-intensity areas (n = 72) were present in 81% of patients. The 26% of lesions seen in the central gland all correlated with cystic atrophy. Of the 53 lesions seen in the peripheral prostate, 47 (89%) were cystic atrophy without associated cancer, four (7.5%) cystic atrophy with cancer, and two (3.8%) focal inflammation. Focal low-signal-intensity areas (n = 42) were present in 60% of patients. Of the 31% of lesions in the central prostate, one-fifth correlated with benign prostatic hyperplasia (BPH) and four-fifths with fibrous tissue. Of the 69% of peripheral lesions, 83% corresponded to fibrous tissue, 10% to BPH, and 7% to normal tissue. Mixed lesions (n = 42) were present in 64% of patients; 86% of these were located centrally and 14% peripherally. All mixed central lesions were BPH; the peripheral lesions were areas of combined cystic atrophy and fibrosis. BPH of low or mixed signal intensity can extend into the peripheral prostate and mimic cancer. High-intensity cystic atrophy associated with cancer can mimic normal tissue.
