case of polypoid and papillary cystitis mimicking an advanced bladder carcinoma with invasion of perivesical fat

A rare case of polypoid and papillary cystitis without a history of catheterization is reported. A 69-year-old man was admitted to our hospital because of pain during urination and gross hematuria. The cystscopic and imaging findings including ultrasound, CT, and MR image showed an irregular wall thickening and stranding in the perivesical fat, which indicated an advanced bladder carcinoma, but histopathological findings obtained by transurethral resection revealed polypoid and papillary cystitis. Such benign lesions need to be discussed in the differential diagnosis of patients with bladder tumor to avoid excessive resection

Consensus Report of the 4th International Forum for Gadolinium-Ethoxybenzyl-Diethylenetriamine Pentaacetic Acid Magnetic Resonance Imaging

This paper reports on issues relating to the optimal use of gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid magnetic resonance imaging (Gd-EOB-DTPA MR imaging) together with the generation of consensus statements from a working group meeting, which was held in Seoul, Korea (2010). Gd-EOB-DTPA has been shown to improve the detection and characterization of liver lesions, and the information provided by the hepatobiliary phase is proving particularly useful in differential diagnoses and in the characterization of small lesions (around 1-1.5 cm). Discussion also focused on advances in the role of organic anion-transporting polypeptide 8 (OATP8) transporters. Gd-EOB-DTPA is also emerging as a promising tool for functional analysis, enabling the calculation of post-surgical liver function in the remaining segments. Updates to current algorithms were also discussed.
