“…In all but three of our cases, the bulk of the tumor was extraluminal. This finding can be very helpful in differentiating it from a bladder adenocarcinoma, which would be expected to be primarily intraluminal [9]. Bladder wall invasion is common in urachal carcinoma and was present in 92% of cases in our series.…”

Computed tomographic appearance of urachal adenocarcinomas: review of 25 cases

2004

Twenty-five cases of surgically proven urachal carcinomas were retrospectively reviewed. The radiological archives at the Armed Forces Institute of Pathology were searched for cases of surgically proven urachal carcinomas that had a computed tomographic (CT) scan as a part of their radiologic evaluation. CT images from all cases were evaluated to determine tumor morphology, presence and localization of calcification, extent of bladder invasion and metastases. Tumor size at presentation averaged 6 cm. Twentyone of 25 (84%) were mixed cystic solid lesions and 4/25 (16%) were completely solid. Calcifications were present in 18/25 (72%), with 11 peripherally located, 3 central only and 4 both. Bladder wall invasion was present in 23/25 (92%), but was seen as an intraluminal mass in only 13/25 (52%). The bulk of the mass was extravesicular in 22/25 (88%). Metastases were present in 12/25 (48%). Our series supports observations from other smaller series that a midline, calcified, supravesicular mass is highly suspicious, if not pathognomonic, for urachal carcinoma.

“…It resisted complete diagnosis until imaging investigations, exploratory laparotomy, and histopathology were correlated. Thus, the importance of investigations in urachal lumps is again underscored here, which was stressed previously [4,5].…”

“…This group consists of adenomas, fibromas, fibroadenomas, fibromyomas, and hamartomas [2]. These benign tumors must be thoroughly evaluated owing to the potential confusion they create in the diagnosis of abdominal lumps as a whole [3,4,9].…”

“…Anomalies of the urachus are associated with epithelial metaplasia of the urachus from a transitional to columnar or glandular variety, resulting in malignancy [2]. Urachal carcinoma usually presents as mucinous adenocarcinoma very near the apex of the bladder on the inner aspect of the upper surface [7]. Other varieties of malignant and benign neoplasms have also been reported with urachal disease.…”

Encysted Urachal Abscess Associated With a Premalignant Lesion in an Adult Male

Congenital anomalies of the urachus are uncommon in adults. If these anomalies persist into adulthood, they very frequently present as complications of the anatomical entity. Encysted urachal abscesses with associated premalignant urothelium of the bladder wall have been very rarely reported. A 56-year-old male presented with infraumbilical pain and swelling. He was diagnosed as having an infected urachal cyst. The cyst did not communicate with the bladder or the umbilicus. On surgical exploration, the interior of the bladder wall near the urachal connection showed an exophytic mass. Histopathological analysis revealed that it was an exophytic papillomatous metaplasia of the bladder urothelium. The remnants of urothelium within the urachal cyst demonstrated normal transitional epithelium. Long-term follow-up was recommended because the features of papillary urothelial neoplasm exhibit a low malignancy potential. The present case is unique because it presents a rare combination of: (1) an encysted urachal abscess, (2) a blind urachal diverticulum, and (3) an exophytic, potentially malignant papillomatous lesion of the bladder epithelium close to its apex.
