1/26. Inflammatory pseudotumor of the bladder: MR findings.We report a case of inflammatory pseudotumor of the bladder in a 29-year-old woman with gross hematuria that was considered as embryonal rhabdomyosarcoma on biopsy specimens. MRI demonstrated a polypoid tumor covered by clot, which disrupted the low intensity of the bladder wall. The lesion exhibited an intermediate signal on T1-weighted images and prominent high intensity on T2-weighted images and was markedly enhanced. A pathologic study revealed a tumor of myxoid stroma invading into the deep muscular layer of the bladder wall.- - - - - - - - - - ranking = 1keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
2/26. Inflammatory pseudotumor of the urinary bladder and sigmoid colon.We report an unusual case of an inflammatory pseudotumor of the bladder. A biopsy specimen prior to surgical treatment suggested leiomyosarcoma, and computerized tomography and magnetic resonance imaging strongly suggested bladder tumor with sigmoid colon invasion. Accordingly, radical surgical treatment consisting of total cystectomy, anterior resection of the sigmoid colon, and ileal conduit was performed. After operation, however, histological examination revealed an inflammatory pseudotumor of bladder and sigmoid colon. These findings were confirmed by immunohistochemical staining for smooth muscle specific actin, desmin, S-100, and vimentin. Histological examination revealed a diverticulum of the sigmoid colon in the middle of the pseudotumor, and this diverticulum may have ruptured to cause the inflammatory pseudotumor of bladder and sigmoid colon.- - - - - - - - - - ranking = 2.4763530612607keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
3/26. Spontaneous regression of inflammatory pseudotumor of the urinary bladder.Inflammatory pseudotumor of the urinary bladder is a benign proliferative lesion of the submucosa and its treatment has not yet been established. Here we present a case of spontaneously regressed inflammatory pseudotumor of the urinary bladder.- - - - - - - - - - ranking = 3.5786725948504keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
4/26. Inflammatory pseudotumor of urinary bladder.A previously healthy 44-year-old male was admitted with the chief complaint of intermittent gross hematuria. On initial ultrasonographic and CT examination, a grossly protruding intravesical tumor was noted and, under the impression of a malignant bladder tumor, transurethral resection was performed. The histological findings were spindle cells with elongated cytoplasm with rare mitotic figures distributed in myxoid stroma, consistent with diagnosis of inflammatory pseudotumor of the bladder. The benign nature of this tumor warrants conservative surgical management, usually consisting of transurethral resection or partial cystectomy. No reports of metastasis have been reported following complete excision. Therefore, any suspicion and recognition of this entity is imperative to avoid performing an irreversible radical procedure.- - - - - - - - - - ranking = 1keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
5/26. Granulomatous renal pseudotumor in Wegener's granulomatosis: imaging findings in one case.Wegener's granulomatosis is a clinicopathological entity characterized by necrotizing granulomatous angiitis involving the upper- and/or lower respiratory tract and the kidneys. Renal involvement is usually characterized by a rapidly progressive necrotizing glomerulonephritis. A case is presented of a patient who developed renal failure and presented a solitary pseudotumoral lesion in the upper pole of the left kidney. Imaging characteristics on US, CT and MR imaging are discussed. The diagnosis was confirmed with ultrasound-guided needle biopsy.- - - - - - - - - - ranking = 0.37403352767095keywords = pseudotumor (Clic here for more details about this article) |
6/26. Inflammatory pseudotumor of the urinary bladder in a child.The inflammatory pseudotumor of the urinary bladder is rare, especially in children. It is a benign proliferative lesion of the submucosal stroma easily mistaken for a sarcoma clinically, so it should be differentiated from a malignant neoplasm. We report the case of bladder inflammatory pseudotumor in a 7-year-old girl.- - - - - - - - - - ranking = 1.7007731778632keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
7/26. Inflammatory pseudotumor of the bladder in neonates.Inflammatory pseudotumors of the bladder are rare in children. We describe a 7-day-old male neonate with inflammatory pseudotumor of the bladder. He presented with a 3-day history of macroscopic hematuria. ultrasonography, computed tomography and cystoscopy showed an intravesical mass arising from the right lateral wall. Pathologic findings obtained by open excision revealed that the tumor had spindle-shaped cells without significant atypia infiltrating into submucosal fibrous tissue. There has been no evidence of recurrent tumor 12 months post-operatively. To our knowledge our case is the first presentation in a neonate among the reported pediatric cases.- - - - - - - - - - ranking = 1.0748067055342keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
8/26. Rare pseudotumors of the urinary bladder in childhood.We report two cases of inflammatory pseudotumors of the urinary bladder, one case of a chronic granulomatous pseudotumor (CGT) and one case of a pseudosarcomatous myofibroblastic (fibromyxoid) tumor (PMT). Both tumors resembled malignancies such as rhabdomyosarcomas regarding clinical appearance and imaging findings and represent rare urinary bladder tumors. The imaging findings on unenhanced and contrast-enhanced MRI as well as histological specimen are presented. Final diagnosis was made following elective surgery. Differential diagnosis of urinary bladder tumors as well as the imaging findings of these clinically comparable cases are discussed. awareness of these benign lesions may prevent patients from inappropriate therapies such as chemotherapy or radiation therapy.- - - - - - - - - - ranking = 1.0748067055342keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
9/26. Inflammatory pseudotumor of the urinary bladder: a report of five cases and review of the literature.We describe five patients who recently presented with gross hematuria secondary to inflammatory pseudotumors of the bladder along with a review of the literature. At presentation, four of the five patients were clinically misdiagnosed as malignancies of which two were further believed to be leiomyosarcomas on initial histological examination because of their spindle-cell appearance. Conservative excision either by transurethral resection or partial cystectomy was curative in all cases. The main importance of these rare, benign lesions is to differentiate them from malignant tumors for which they may be mistaken, thus avoiding radical surgery and its attendant complications.- - - - - - - - - - ranking = 1keywords = inflammatory pseudotumor, pseudotumor (Clic here for more details about this article) |
10/26. Pedunculated prolapsing bladder hematoma (pseudotumor) mimicking an anterior vaginal polyp--a clinical curiosity and rare complication of transurethral resection of bladder tumor.A young woman who presented with a recurrent bladder tumor was detected on follow up to be harboring a prolapsed bladder tumor at the external urinary meatus mimicking an anterior vaginal polyp. Excision and histopathological examination revealed an organized hematoma (pseudotumor). The literature regarding this clinical curiosity and its differential diagnosis is reviewed and discussed.- - - - - - - - - - ranking = 0.37403352767095keywords = pseudotumor (Clic here for more details about this article) |
