ABSTRACT
There is no definitive approach for assessing mesenteric ischemia and determining the optimal timing for endovascular intervention in the management of spontaneous isolated dissection of the superior mesenteric artery (SISMAD). A 56-year-old male with acute abdominal pain was diagnosed with SISMAD. After evaluating mesenteric ischemia through mesenteric fractional flow reserve (FFR), FFR was 0.72, and the patient was recommended conservative treatment for SISMAD, which involves fasting, total parenteral nutrition, and anticoagulation. The patient's syndrome was relieved after conservative treatment for 14 days without stent implantation. Over the next 5 years, no recurrence of abdominal pain or worsening of SISMAD was observed in the patient. Assessing the severity of mesenteric ischemia can be done through mesenteric FFR. Upon confirmation of the exclusion of risks related to dilatation or rupture of SISMAD aneurysm, an approach in favor of conservative management for SISMAD may indeed be considered pragmatic when the FFR exceeds 0.72.
ABSTRACT
BACKGROUND: Aggressive angiomyxoma (AA) is a rare tumor that typically occurs in the pelvis and perineum, most commonly in women of reproductive age. However, no para-ureteral AA has been reported according to the literature. Case presentation We herein describe the first case of para-ureteral AA. A 62-year-old male presented to our institute in March 2017 with a para-ureteral mass that was 15 mm in diameter incidentally. No symptom was observed and laboratory analysis was unremarkable. Magnetic resonance and computed tomography imaging showed a non-enhancing mass abutting the left ureter without causing obstruction. Laparoscopic resection of the mass was performed without injury to the ureter. Pathologic and immunohistochemical results were consistent with AA. Till now, no recurrence was noticed. CONCLUSIONS: We reported a rare case of para-ureteral AA, along with a literature review. Early diagnosis, proper surgical plan and long-term close follow-up is recommended for its high risk of recurrence and malignant potential.

OBJECTIVES: To estimate the impact of peri-prostatic fat (PPF) measurements using preoperative magnetic resonance imaging on the prediction of prostate cancer (PCa) with transrectal ultrasound-guided biopsy. PATIENTS AND METHODS: We performed a retrospective 2-center study on 660 consecutive patients receiving transrectal ultrasound-guided biopsy-biopsy from June 2016 to October 2018. Pathologic and immunohistochemical characteristics were collected. PPF measurements including PPF area (PPFA) and PPFA to prostate area (PA) ratio (PPFA/PA) were assessed by preoperative staging magnetic resonance imaging. Clinical variables were correlated with Gleason score by using Spearman (ρ) correlation coefficients. Multivariable analysis was performed to identify independent predictors of PCa. The diagnostic performance was estimated using ROC curves. RESULTS: The Gleason score was significantly correlated with age (ρâ¯=â¯0.114, Pâ¯=â¯0.035), prostate-specific antigen (PSA) (ρâ¯=â¯0.482, P < 0.001), PIRADS scoring (ρâ¯=â¯0.403, P < 0.001) and PPFA/PA (ρâ¯=â¯0.238, P < 0.001). Multivariate analysis revealed that PPFA/PA, age, digital rectal examination, family history of PCa, PSA, and PIRADS scoring were independently predictive of PCa. The ROC AUC to detect PCa or clinically significant PCa (CS-PCa; Gleason Score 3â¯+â¯4 or greater) improved with the addition of PPFA/PA (PCa: 0.93 vs. 0.89; CS-PCa: 0.92 vs. 0.90). CONCLUSION: PPFA/PA is an independent predictor for PCa along with age, digital rectal examination, family history of PCa, PSA, and PIRADS scoring. PPF measurements especially PPFA/PA may help detect PCa or CS-PCa, thus helping improve PCa risk stratification and screening to avoid unnecessary biopsies.
