59-year-old male with history of elevated PSA. Patient reports he was diagnosed with prostate cancer at an outside hospital although repeat biopsy at this institution revealed no malignancy. This is the patient's one year follow-up. PELVIS:PROSTATE:Prostate Size: 5.9 x 4.8 x 5.5 cm.Peripheral Zone: There is a large area of T1 hyperintensity involving the right peripheral zone limiting evaluation for lesions within this region. Redemonstrated within this region is the previously noted T2 hypointense focus in the left paramedian mid gland with corresponding restricted diffusion and early arterial enhancement. This finding is indeterminate due to the presence of T1 hyperintensity. In the right midgland peripheral zone, there is a linear hypointense focus with corresponding restricted diffusion that is unusual for malignancy.Central Gland: Severe degree of benign prostatic hypertrophy. Seminal Vesicles: No significant abnormality noted.Extracapsular Extension: The left paramedian mid gland lesion abuts the capsule. The far left portion of this lesion may demonstrate some extracapsular extension.BLADDER: No significant abnormality noted.LYMPH NODES: Scattered small right common iliac and pelvic wall lymph nodes are noted. No pathologically enlarged lymph nodes.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Large area of T1 hyperintensity involving the right peripheral zone may represent hemorrhage from prior biopsy and limits evaluation for lesions within this region. Within this limitation, again noted is a T2 hypointense focus in the peripheral zone that is indeterminate.2.Otherwise, no definite lesion suspicious for malignancy is identified.
