53-year-old male with newly diagnosed prostate cancer undergoing prostatectomy. Patient is on research protocol.Pathology: Prostatic adenocarcinoma, Gleason grade 3+4=7 in the left lateral base PELVIS:PROSTATE:Prostate Size: 4.5 x 2.2 cmPeripheral Zone: There is a T2 hypointense lesion in the left lateral mid gland and base with corresponding hypointensity on ADC and early contrast enhancement consistent with history of adenocarcinoma. This lesion measures 14 x 10 mm (series 701, image 16). This lesion may abut the left perineural fat; although discrete perineural invasion cannot be excluded (series 2/2/2001, image 984).Additionally, there are regions of T1 hyperintensity and T2 hypointensity in the peripheral zone, most likely secondary to hemorrhage from previous biopsy.Central Gland: There are benign appearing hyperplastic nodules in the central gland.Seminal Vesicles: Seminal vesicles are unremarkable.Extracapsular Extension: This lesion may abut the left perineural fat; although, perineural invasion cannot be excluded (series 2201, image 984).BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: There is a T2 hyperintense focus in the right internal obturator muscle without contrast enhancement (series 701, image 16) most consistent with a benign lesion.
Left lateral mid gland and base lesion as above consistent with adenocarcinoma. The lesion may abut the left perineural fat; although, perineural invasion cannot be excluded.
