However causes of delayed separation of cord such as urachal
anomalies, antibiotic administration, prematurity and low birth weight must be excluded.
Between July 22, 2015 and December 31, 2016, 48 patients were accrued with previously treated metastatic urothelial carcinoma (mUC, n=19), urachal
adenocarcinoma, squamous cell carcinoma of the bladder or urethra, germ cell tumor, castration-resistant prostate cancer, renal cell carcinoma, trophoblastic tumor, sertoli cell tumor or penile squamous cell carcinoma and treated in two parts.
The most likely possible differential diagnoses were: urachal
cyst, degenerated pedunculated subserous fibroid, peritoneal inclusion cyst, and ovarian dermoid cyst.
malignancies are rare and represents less than 1% of all bladder neoplasms.
The differential diagnosis to be considered on imaging appearance include bladder diverticulum, urachal
cyst, Mullerian duct cyst, or a Seminal vesicle cyst.
mucinous cystic tumours are a rare finding of excised urachal
It was decided that the urachal
mass be removed at the time the hydrocele was addressed.
The full differential diagnosis of nongynecologic pelvic masses is extensive and includes mesenteric duplication cysts, presacral masses, pelvic kidney, peritoneal inclusion cysts, and urachal
cysts (TABLE, page 22).
138,139) Similarly, the mucinous epithelium of metastatic pancreatic, colorectal, endocervical, urachal
, and lung adenocarcinomas may appear benign or as borderline ovarian primary tumor, suggesting an origin of the neoplasm in the ovary.
Sinus in Calf (Bos indicus): Diagnosis and Surgical Treatment
According to this study the urachal
remnant alone was found in 15 calves umbilical artery remnant alone in one calf and the umbilical vein remnant alone in 4 calves.
