Value of Endorectal MRI in Romanian Men for High Risk of Prostate Cancer: MRI Findings Compared with Saturation Biopsy.

PURPOSE: To evaluate the potentials of T2 weighted (T2W)MRI and diffusion weighted (DW) MRI for prostate cancer(PCa) detection, local staging and treatment planning in high-risk group. MATERIAL AND METHODS: Endorectal MRI was performed in 17 Romanian men (median age: 66 years; range: 58 75 years), prostate specific antigen (PSA) serum levels (median: 20 ng mL; range: 8.6 100 ng mL) with positive findings for PCa(median Gleason score: 8; range: 7 - 9). Imaging findings were compared to standarised 20-core transperineal saturation biopsy. The prostate was divided into 16 standart sectors(10 posterior and 6 anterior). RESULTS: Overall, prostate cancer was detected in 16 patients(94%) on DW-MRI alone and in all 17 patients (100%) on T2W-MRI alone, and on combined imaging. On T2W-MRI165 sectors out of 272 were suspicious for PCa and 124 (75%)were cancer positive. On DW-MRI 126 sectors out of 272 were suspicious for PCa and 118 (95%) were cancer positive. On the combined imaging approach 134 sectors out of 272 were suspicious for PCa and 126 (94%) were cancer positive. This resulted in diagnostic accuracies per sector of 76% for T2WMRI, 86% for DW-MRI and 89% for combined imaging. Multifocal PCa was confirmed both on MR imaging and by biopsy in 8 of the 17 men (47%) Extra capsular extension(ECE) or seminal vesicles invasion (SVI) was highly suspected in 8 (47%) respectively 7 (41%) of the 17 patients. 6 patients(35%) presented both ECE and SVI. MRI findings were taken into account for treatment planning and none of these patients underwent radical prostatectomy and instead was treated with palliative cryotherapy, radiotherapy and hormone therapy. CONCLUSIONS: Endorectal MRI is highly accurate in PCa detection in the high-risk group and seems to have an important role in local staging and treatment planning for Romanian population.

Chronic pancreatitis with hemosuccus pancreaticus. The diagnostic contribution of computed tomography and contrast enhanced ultrasonography--case report.

Hemosuccus pancreaticus is defined as upper gastrointestinal hemorrhage from the ampulla of Vater via the pancreatic duct. It is a rare disease, with non-specific presentation, challenging to diagnose and difficult to treat, with high mortality rates in untreated patients with massive bleeding. Given the intermittent nature of the bleeding, delays in diagnosis frequently occur. Timely diagnosis and treatment seem to result in markedly reduced mortality, therefore we emphasize the diagnostic contribution of imaging techniques by presenting the case of a patient with chronic pancreatitis in whom computed tomography established the diagnosis of blood in the Wirsung duct and contrast-enhanced ultrasound brought its added value by excluding the active bleeding.
