55-year-old male with history of malignant neoplasm of the prostate. PELVIS:PROSTATE:Prostate Size: 4.5 x 3.5 x 4 cm (TR x AP x CC)Peripheral Zone: Extensive lobulated decreased T2 signal intensity within the left peripheral zone. Crossing the midline at the mid gland apex, there is a 2.8 x 1.5 cm T2 hypointense lesion (axial series 901 images of 14-15). This broad-based lesion abuts the capsule, and neurovascular invasion is suggested (axial series 901 image 17). Postcontrast imaging is noncontributory.The right mid peripheral zone demonstrates amorphous linear appearing T2 hypointense signal intensity, and posterolateral capsular invasion is also suspected.Central Gland: No significant abnormality.Seminal Vesicles: Suspicious low T2 signal intensity of the left seminal vesicle.Extracapsular Extension: As above.BLADDER: No significant abnormality noted.LYMPH NODES: Mildly prominent inguinal and sidewall lymph nodes, nonspecific. A left inguinal lymph node measures 1.6 cm (axial series 1601 image 387), and a left external iliac measures 0.9 cm (axial series 1601 image 398).BONES, SOFT TISSUES: Mottled marrow signal intensity that is low on T1 and T2 of the pelvis that is most evident in the bilateral inferior pubic rami (axial series 801 image 4; axial series 901 image 4) and bilateral iliac wings (coronal series 701 image 24).OTHER: No significant abnormality noted.
1.MRI findings compatible with extensive disease in the mid peripheral zone as described above.2.Mottled low signal intensity of the bone marrow on both T1 and T2. A review of the medical record indicates a history of thalassemia, which is compatible with these findings.
