¹⁸F-FDG PET/MR Refines Evaluation in Newly Diagnosed Metastatic Urethral Adenocarcinoma / 대한핵의학회잡지

We described the clinical impact of ¹⁸F-FDG PET/MR in refining the evaluation of a 39-year-old female with newly diagnosed metastatic urethral adenocarcinoma.We detailed the diagnostic imaging workup focusing our attention on the CT, MR, and ¹⁸F-FDG PET/MR different findings. In this case, ¹⁸F-FDG PET/MR imaging evaluation resulted not only effective but also altered staging and spared additional invasive procedures in the assessment of a metastatic urethral adenocarcinoma. Combining a highly sensitive PET with the increase tissue resolution of MR (PET/MR) may improve abdominal and pelvic lesion detection outperforming PET/CT for this indication.

A rare case of primary female urethral adenocarcinoma: Columnar type with colonic adenocarcinoma features

Female urethral carcinoma is extremely rare and accounts for 0.02% of all women's cancers and <1% of cancers in the female genitourinary tract. Adenocarcinoma accounts for only 10% of urethral carcinomas in females. Due to their location, presentation is usually late and tumors are often missed on physical examination. As in this case, nonspecific symptoms in the early stages may delay the diagnosis in most patients. Herein, we present an extremely rare case of the columnar type of primary female urethral adenocarcinoma exhibiting colonic adenocarcinoma features which to the authors' best knowledge has not been reported to date. The present study emphasizes the importance of a careful clinical examination and also highlights the role of imaging studies, and biopsy in making an accurate preoperative diagnosis of this rare disease. The disease may have devastating sequelae due to local and metastatic involvement if not recognized and treated earlier.

A Case of Primary Urethral Adenocarcinoma in Female / 대한비뇨기과학회지

Primary carcinoma of the female urethra is an uncommon neoplasm that accounts for less than 0.02% of all malignant diseases occurring in women. Especially reported adenocarcinoma is rare now in the literature. We add one case of urethral adenocarcinoma in 61 years old female treated by total urethrectomy with resection of corresponding bladder neck, and suprapubic neourethrelization.
