“…rEfErENcEs are characterized by early transmural invasion and have a tendency for higher histopathological grades [4]. Cheng et al corroborated this result and indicated that neoplasms originating in a bladder diverticulum are characterized by a high incidence of local recurrence [5]. Lack of muscle fibers in the diverticulum makes it difficult to stage the tumor.…”

The incidence of bladder diverticulum is approximately 1.7% in children and 6% in adults. Dysplasia, leukoplakia, and squamous metaplasia and stone formation may develop in diverticulum and sometimes with malignant changes. The most common histological subtype of diverticulum tumors is transitional cell carcinoma (TCC). Herein we report 2 such cases of transitional cell carcinoma arising in diverticulum of the urinary bladder, one of which was associated with diverticular stones.

“…Our patient presented with painless gross hematuria and urinary retention, which are usually the presenting symptoms of the neoplastic changes in bladder urothelium. 4,5 The incidence of neoplastic changes within the bladder diverticulum is estimated at 2% to 10%. 6 There is still no clear pathophysiologic explanation behind these neoplastic changes.…”

“…4 Due to its rarity and lack of systematic clinical studies, there are currently no available guidelines regarding the management of neoplasms arising from intravesical diverticulum. With malignant neoplasms confined to the diverticulum, there is better prognosis than those with extravesical extension.…”

Neoplasms arising from intravesical diverticula are rare and considered by urologists as an important surgical challenge. A hamartomatous lesion noted in a bladder diverticulum has never been reported. To our knowledge, we report the first angiomyolipoma, a subtype of mesenchymal hamartoma uncommonly located extrarenally, seen in a bladder dome diverticulum. We discuss the dilemma on the management of such case, related literature and probable etiology.

“…have also been described. [1,2,4] Bladder tumours are more common in men, the incidence increasing with age. [5] Local endoscopic transurethral resection and intravesical instillation of adjuvant chemotherapeutic agents/Bacillus Calmette-Guérin, an immune-modulating agent, are employed for superficial lesions.…”

Transitional cell carcinoma developing in a bladder diverticulum: Early diagnosis by computed tomography

Computed tomography confirmed a left-sided narrow neck urinary bladder diverticulum, with wall thickening, in a 56-year-old man. These findings were initially detected on ultrasonographic investigation. Transitional cell carcinoma was confirmed histologically. There is an increased incidence of neoplastic transformation in urinary bladder diverticuli, and therefore an early search for subtle imaging signs should be implemented. A 56-year-old man presented with painless haematuria and occasional right-sided flank pain. Routine investigations were non-contributory, with serum creatinine levels of 1.4 mg/dl. Sonography showed left-sided grade 1 hydronephrosis and a dilated left ureter. A narrow neck urinary bladder diverticulum was identified near the left vesico-ureteric junction. The left terminal ureter tapered abruptly, medial to the bladder diverticulum.The patient was referred for a CT scan, which confirmed the narrow neck bladder diverticulum and identified minimal thickening of the medial wall, resulting in left ureteric dilatation with hydronephrosis. There was minimal enhancement of the medial diverticular wall, which was initially not appreciated on the 5-minute delayed phase scan, owing to the layering effect of excreted contrast in the bladder lumen. However, it was identified on the prone delayed-phase CT examination (Fig. 1D). The finding on this image prompted cystoscopy and guided biopsy. Subsequent histopathological examination confirmed a transitional cell carcinoma (TCC). The diverticulum was surgically removed, with wide
