The development of pseudotumors is not uncommon with metal-on-metal total hip arthroplasty. Pseudotumors that dissect into the retroperitoneal space can cause symptoms of nerve compression. We describe a case of a 53-year-old male with a metal-on-metal total hip arthroplasty who developed mild symptoms of a femoral nerve neuropathy 6 years postoperatively. Revision arthroplasty to a ceramic-on-...

Inflammatory pseudotumors are a relatively uncommon pathology of uncertain etiology, generally considered to be reactive in origin. They may be observed in different locations as single or multiple masses. One of the possible forms of presentation is intrapulmonary. Despite its low frequency, this pathology should be considered in the differential diagnosis of lung nodules, even though the hist...

BACKGROUND Inflammatory pseudotumors of the bladder are rare in newborns. Considering the potential for malignancy, invasive diagnostic assessment and therapeutic surgical excision have been described as the approach of choice. CASE REPORT We present a case of urethral catheter-related injury causing multifocal lesions simulating inflammatory pseudotumors of the bladder, diagnosed in a newbor...

On September 25th, 2003, a 39-year-old man complained of asymptomatic gross hematuria. He was admitted to a nearby hospital and evaluated. Cystoscopy revealed a non-papillary broad base tumor in the anterior wall of the bladder. On October 2nd, a TUR-Bt was performed. The pathological diagnosis was difficult to determine because mitosis and nuclear pleomorphism were apparent. He next came to ou...

BACKGROUND Inflammatory pseudotumors were mostly encountered in the lung. Retroperitoneal inflammatory pseudotumors are relatively rare. Although laparoscopic surgery with a modified flank position is widely performed for retroperitoneal tumors, we placed the patient in the supine position to maintain the normal anatomical view of the retroperitoneal space. We report a case of retroperitoneal i...
