In some patients, inflammatory changes can be so intense that infravesical obstruction with bilateral hydronephrosis is created. Differentiating pseudo-tumoral cystitis (Hoeffel et al. 1993) and a tumor can be difficult and occasionally may require more sophisticated imaging modalities (MRI, cystoscopy and biopsy) (Fig. 6.13). This applies to another rare inflammatory condition of the urinary bladder of unknown origin, eosinophilic cystitis. This inflammatory process is characterized by eosinophilic infiltration of the bladder wall. MR findings of this...

There have been several reports of erythematous blistering skin eruption of the palms and soles affecting patients treated with intravesical mitomycin. This has been attributed to contact dermatitis, but more widespread skin involvement and an association with eosinophilic interstitial cystitis suggest that it may be a more generalized allergic reaction (16-20). 

Urinary tract dysfunction has been associated with recreational use of ketamine [43 ]. It was first described in a series of nine patients, all of whom were daily ketamine users, who presented with severe dys-uria, frequency, urgency, and gross hematuria [44 J. The urine cultures were sterile in all cases. CT scans showed marked thickening of the bladder wall, a small capacity, and perivesicular stranding, consistent with severe inflammation. All had severe ulcerative cystitis. Biopsies in four patients showed epithelial denudation and inflammation with a mild eosinophilic infiltrate. Withdrawal of ketamine, and treatment with pentosan polysulfate, gave symptomatic relief.
