History of prostate cancer. Presurgical evaluation. PELVIS:PROSTATE:Prostate Size: 4.8 x 3.8 x 2.7 cmPeripheral Zone: There is heterogeneous but diffuse low T2 signal throughout the left peripheral zone. This low signal becomes particularly confluent and prominent along the left lateral border of the prostate (series 701 image 16). These regions have mild restricted diffusion and early arterial enhancement compatible with diffuse tumor.There is an additional region of more confluent low T2 signal in the right mid gland extending into the right apex which measures 10 x 8 mm in axial dimension (series 901 image 21). This is associated with mild restricted diffusion and early arterial enhancement. Compatible with additional tumor.Central Gland: Nodular changes of benign prostatic hypertrophy.Seminal Vesicles: No significant abnormality or tumor involvement is identified.Extracapsular Extension: There is extension of abnormal signal along the posterior border of the right peripheral zone on the ADC images (series 503 image 344). This however is not correlated with the findings on the T2 and contrast enhanced sequences. For this remains equivocal for minimal extracapsular extension. The abnormal signal does not extend to involve the neurovascular bundle.BLADDER: No significant abnormality noted.LYMPH NODES: No pelvic or inguinal lymphadenopathy.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Diffuse abnormal signal throughout both the left and right peripheral zones compatible with diffuse tumor, particularly in light of biopsy history.2.Equivocal findings for possible minimal extracapsular extension along the posterior aspect of the right peripheral zone as described.
