Degeneration of the symphysis pubis presenting as a submucosal urinary bladder tumour.

Urinary bladder sonography is a sensitive diagnostic technique used for visualizing urinary bladder tumours. The aim of our communication is to present a case of a pseudotumour of the urinary bladder originating from the symphysis pubis syndesmosis. A 58-year-old woman was seen by a urologist with symptoms of lower urinary tract infection. Urinary bladder sonography was performed, followed by magnetic resonance imaging. Sonographic images of the bladder showed an exophytic mass on the urinary bladder's anterior wall. A transurethral resection of the tumour was performed. A histopathological examination revealed a necrotic extramural mass, without traits of malignancy. The mass reappeared in the follow-up vesical sonography. Subsequently, its transurethral resection was repeated with the same histopathological findings. The next urinary bladder sonography revealed the presence of the mass again. Pelvic magnetic resonance imaging was performed, which showed advanced degenerative changes in the pubic symphysis syndesmosis that protruded into the bladder, imitating a urinary bladder tumour. To avoid unnecessary surgery, both radiologists and urologists should be made aware that there is a possibility of similar cases in patients. Magnetic resonance imaging enabled correct determination of the primary site of the growth, which, together with the histopathological examination results, influenced the choice of the implemented therapeutic procedures.

Incidental sonographic detection of mucosa-associated lymphoid tissue lymphoma of the urinary bladder found in a very young woman: report of a case.

We report a rare case of a mucosa-associated lymphoid tissue (MALT)-type lymphoma of the bladder, incidentally found on sonography in a 17-year-old girl during the workup of arterial hypertension. The diagnosis was established by a transurethral biopsy. Treatment consisted of transurethral resection of the bladder tumor and subsequent chemotherapy. To the best of our knowledge, this is the youngest patient with asymptomatic MALT-type lymphoma of the urinary bladder.

The accuracy of a postprocessing technique--volume render mode--in three-dimensional endoanal ultrasonography of anal abscesses and fistulas.

OBJECTIVE: This study aimed to evaluate the accuracy of a 3-dimensional volume render mode endoanal ultrasonography in the assessment of anal abscesses and fistulas. PATIENTS AND METHODS: Three-dimensional endoanal ultrasonography was performed preoperatively in 62 patients with clinical diagnoses of an anal abscess and/or an anal fistula. The accuracy of a volume render mode endoanal ultrasonography was evaluated blindly by 2 observers through a retrospective analysis of all the stored images of anal abscesses and fistulas. Differences in classification of the type of anal abscesses and in determination of the type and location of internal openings of anal fistulas were assessed. RESULTS: In classification of the primary tract, the agreement between the volume render mode endoanal ultrasonography and surgery was much higher than that for the 3-dimensional endoanal ultrasonography (marginal homogeneity test P > .1, κ = 0.96, and marginal homogeneity test P = .0048, κ = 0.28, respectively). In localizing the internal openings and in classifying anal abscesses, the agreement for both methods with surgery was identical. The interobserver agreement showed complete agreement (100%) with regard to luminance and thickness parameters and very high accuracy for the opacity and filter parameters. CONCLUSIONS: This study demonstrated that volume render mode endoanal ultrasonography is a useful adjunct method to the 3-dimensional endoanal ultrasonography, showing better classification results of the types of anal fistulas.

Ectopic decidual reaction in the urinary bladder presenting as a vesical tumor.

A urinary bladder tumor in young pregnant women is a very rare finding. It may bring diagnostic problems despite use of advanced imaging techniques. We report on a case of an exceedingly rare occurrence of a decidual reaction in the urinary bladder of a pregnant young woman. To the best of our knowledge, it is the first such case reported in published medical data. The final diagnosis was possible only after histopathologic assessment of a specimen obtained during diagnostic cystoscopy, which showed typical decidual changes within detrusor muscle, without ectopic endometrium, which could suggest more frequent vesical endometriosis.
