“…It was once proposed that MRI by itself could confirm this diagnosis, nonetheless and considering it cannot differentiate mesenchymal tumors from the more common transitional cell tumors (TCT) the histopathology study is always necessary to confirm (3,4). Recent findings, nonetheless, indicate that the Apparent Diffusion Coefficient -obtained by diffusion--weighted magnetic resonance-values are significantly lower in malignant lesions (e.g.…”

The case of a 71-year-old woman who presented with one year history of pelvic pain and occasional dysuria is reported. Computed tomography and Magnetic Resonance Imaging revealed a well defined intramural bladder mass. The histological findings of the surgical specimen confirmed a leiomyoma of the urinary bladder. The clinical presentation, imaging findings and management of this relatively rare benign tumor are discussed.

“…Leiomyomas are classified into three different types based on location -endovesical, intramural and extravesical. 6 Endovesical leiomyoma is the most common location, in 63-86% of cases. Intramural leiomyomas present in 3-7% and extravesical location in 11-30%, with female preponderance (70%) affecting patients in their third to sixth decades [3][4][5][6][7].…”

Introduction: Bladder leiomyomas are benign mesenchymal neoplasms with only 250 cases reported worldwide to date. They can be asymptomatic, but the majority present with obstructive symptoms (49%), irritative symptoms (38%) and hematuria (11%). The importance of recognizing their characteristic features, leading to their correct treatment, is fundamental. Methods:Case report and review of pertinent English medical literature.Results: A 53 year old lady presented with urgency and frequency for 3 months, with two episodes of painless total hematuria. She was catheterized for acute urinary retention elsewhere. Clinical examination was unremarkable. Ultrasound (US) showed a heterogeneously hypoechoic lesion of 4 x 3 cm in bladder base. Contrast enhanced computed tomogram (CECT) showed a 5 x 4 cm well circumscribed hypodense lesion arising from trigone, without hydroureteronephrosis. A mucosal bulge measuring around 5 x 5 cm was seen in the right lateral wall extending upto bladder neck at cystoscopy. Transurethral resection (TUR) was done and biopsy showed fragments of tumor tissue composed of spindle cells arranged in sheets and interlacing fascicles, without mitosis or necrosis, suggestive of leiomyoma bladder. Immunohistochemistry showed SMA and desmin positivity. Complete TUR enuceation was done and patient is doing well at 6 months of follow up without recurrence or hematuria. Conclusion:Leiomyoma of the bladder should be kept in mind in chronic lower urinary tract symptoms with acute urinary retention and hematuria in patients presenting in the third to sixth decade, especially in women. A complete assessment to look for endovesical leiomyoma should be made.

“…It may occur at different ages [3][4][5], can be asymptomatic, or can present in a varied manner, depending on the location of the tumor, with obstructive symptoms, irritating symptoms, hematuria, pelvic mass, and pelvic and flank pain [3][4][5][6][7][8]. Leiomyomas arise in the submucosa, but the growth may be submucosal (7%), intravesical (63%), or extravesical (30%) [5].…”

“…Patients with leiomyoma of the bladder are often found at imaging after referring to clinicians for urinary frequency, urinary urgency, gross hematuria, and other symptoms; but some are asymptomatic [3][4][5]. It exhibits characteristics similar to those of uterine myomas on US, CT and MRI [3][4][5][6][7][8].…”

Imaging findings of atypical leiomyoma of the urinary bladder simulating bladder cancer: a case report and literature review

Atypical bladder leiomyoma is a rare bladder tumor that is difficult to be correctly identified by imaging techniques or cystoscopy. We present the imaging characteristics of an atypical bladder leiomyoma and review the relative literature, with the aim of enhancing awareness of the differential diagnosis of bladder leiomyoma, to avoid and reduce misdiagnosis. The imaging characteristics of the atypical leiomyoma were the cauliflower shaped, abundant vascularity, and calcification foci on the surface of the tumor. The patient was misdiagnosed with bladder cancer after an imaging study. The histopathological study established the definitive diagnosis.
