Retroperitoneal Pseudoaneurysm Mimicking Ureteral Calculus: Pitfalls in Diagnosis

Lumbar Artery Pseudoaneurysm: A Complication of Percutaneous Nephrostomy

A 21 year-old male underwent nephrostomy tube insertion for hydronephrosis due to a large para-aortic adenopathy of a testicular tumor. In order to reduce infections during chemotherapy, a ureteral stent was placed. While removing the nephrostomy tube, a pulsatile bleeding was found and a renal angiography was done. A pseudoaneurysm of his first left lumbar (L1) artery communicating with the ne...

Extracorporeal shock wave lithotripsy-induced retroperitoneal hemorrhage in a case of upper ureteral calculus with angiomyolipoma.

Avoiding diagnostic pitfalls in mimics of neoplasia: the importance of a comprehensive diagnostic approach.

Any medical diagnosis should take a multimodal approach, especially those involving tumour-like conditions, as entities that mimic neoplasms have overlapping features and may present detrimental outcomes if they are underdiagnosed. These case reports present diagnostic pitfalls resulting from overdependence on a single diagnostic parameter for three musculoskeletal neoplasm mimics: brown tumour...

Ureteral Strangulation by Fibrosis: A Cold Case Report of Ormand's Disease

Retroperitoneal fibrosis or Ormand's disease is rare in incidence and clinically elusive to diagnosis until obstructive uropathy clinically manifests by the mechanism of ureteral fibrotic strangulation and acute renal failure. We encountered a 50-year-old woman with months of nonspecific abdominal pain and presented with signs and symptoms of acute renal failure. Laboratory data was significant...

Reactive Hyperplastic Lesion of Endodontic Origin Mimicking Pregnancy Tumor: A Case Report

 Gingiva is a common region of inflammatory and reactive lesions. Systemic conditions, including hormonal imbalance in pregnant women, may cause exaggerated response to irritations such as calculus or infection. Therefore, more accurate assessment is necessary to achieve the best decision making in the differential diagnosis and treatment of these patients. In this paper, we present a rea...
