spontaneous Retroperitoneal hemorrhage caused by segmental arterial mediolysis
Reviews in urology, 2006Co-Authors: Courtney K Phillips, Herbert LeporAbstract:Spontaneous Retroperitoneal hemorrhage is a rare clinical entity; signs and symptoms include pain, hematuria, and shock. Spontaneous Retroperitoneal hemorrhage can be caused by tumors, such as renal cell carcinoma and angiomyolipoma; polyarteritis nodosa; and nephritis. The least common cause is segmental arterial mediolysis. Although computed tomography is used for the diagnosis of spontaneous Retroperitoneal hemorrhage, it can miss segmental arterial mediolysis as the cause of the hemorrhage. The diagnosis of segmental arterial mediolysis as a cause of spontaneous Retroperitoneal hemorrhage requires angiography, with pathologic confirmation for a definitive diagnosis.

unusual presentation of right side accessory spleen mimicking a Retroperitoneal tumor
International Journal of Urology, 2008Co-Authors: Chang M Im, Sang H Oh, Dong D Kwon, Kwangsung ParkAbstract:Abstract: An unusual case of right-side Retroperitoneal accessory spleen is presented. A 68-year-old man visited our hospital for the management of incidentally detected Retroperitoneal mass. The computed tomography scan of the abdomen revealed the presence of a Retroperitoneal tumor (4.0 × 3.8 cm) at the right suprarenal space. Laparoscopic excision was carried out with excellent results. On histological examination, the tumor exhibited a structure typical of splenic tissue. This accessory spleen was unusual in its size and location. Though it existed at the right side, surgeons should be aware of the possible existence of accessory spleens for the differential diagnosis of Retroperitoneal tumors.

Retroperitoneal schwannoma mimicking metastatic seminoma case report and literature review
Chinese Journal of Cancer, 2013Co-Authors: Shi Qiang Zhang, Kai Yao, Pei Dong, Zhi Ling Zhang, Fang Jian ZhouAbstract:If a testicular cancer patient has a mass in the retroperitoneum, a metastasis is often the first suspicion, probably leading to improper diagnosis and overtreatment. Here we report a case of Retroperitoneal schwannoma mimicking metastatic seminoma. A 29-year-old man, who had a history of seminoma, presented with a single Retroperitoneal mass suspected to be a metastasis. Because the patient refused radiotherapy, 3 cycles of cisplatin, etoposide, and bleomycin were offered. Post-chemotherapy computed tomography scan revealed persistence of the Retroperitoneal mass, with no change in tumor size or characteristics. Subsequently, Retroperitoneal lymph node dissection was performed. The dissected tissue contained negative lymph nodes but a single mass in the attached fat. Pathology revealed Retroperitoneal schwannoma, which was confirmed by immunohistochemistry. Thus, clinicians should be aware of Retroperitoneal schwannoma and its distinction from metastatic seminoma to avoid misdiagnosis and ensure proper treatment.

the bladder sign an important early marker of Retroperitoneal hemorrhage
Catheterization and Cardiovascular Interventions, 2012Co-Authors: Mark I Freilich, David E Gossman, Steven W Werns, Sanford J. Gips, Zoltan G. Turi, Robert J. ApplegateAbstract:Retroperitoneal hemorrhage remains one of the major complications of cardiac and peripheral vascular catheterization. Its high associated morbidity and mortality require vigilance and early intervention. We report six cases of Retroperitoneal hemorrhage featuring a “bladder sign.” The compression of the bladder described in this series can be visualized on the incidental cystogram that results from contrast given during catheterization. Its significance as a highly specific marker of Retroperitoneal hemorrhage should be appreciated. © 2011 Wiley Periodicals, Inc

spontaneous Retroperitoneal hemorrhage secondary to subcapsular renal hematoma mri findings
Magnetic Resonance Imaging, 2001Co-Authors: Cem N Balci, Levent Onat, Mustafa Sirvanci, Ilter Tufek, Cihan DuranAbstract:Spontaneous Retroperitoneal hemorrhage is a rare intraabdominal bleeding. In this report we present a case of a nontraumatic Retroperitoneal hemorrhage secondary to spontaneous subcapsular renal hematoma. A 54-year-old patient who was under warfarin therapy, developed subcapsular right renal hematoma. Subcapsular and Retroperitoneal hemorrhage were low signal on T1- and T2-weighted images consistent with acute stage of blood. The source of subcapsular hematoma was shown to be the rupture of hemorrhagic renal cyst on MRI. Extension of hemorrhage into the Retroperitoneal space anterior to right psoas muscle was also successfully shown on MRI. Patient underwent nephrectomy and Retroperitoneal blood was evacuated.
