Neurofibroma invading into urinary bladder presenting with symptoms of obstructed defecation and a large perineal hernia.

BACKGROUND

Pelvic floor hernias pose a diagnostic and a treatment challange. Neurofibromatosis is a rare systemic disease, and urinary tract involvement is rare.

CASE PRESENTATION: Here we report a case of a 54-year-old female with multiple neurofibromatosis who presented with features of obstructed defecation and was found to have a large perineal hernia. At surgery, we found an unusual herniation of a large neuropathic bladder and rectum through a perineal defect. She underwent reduction cystoplasty and repair of the pelvic floor using a prolene mesh. Subsequent histopathological examination confirmed a large neurofibroma infiltrating the urinary bladder.

CONCLUSION

Neurofibromatosis of the bladder is rare it should be considered as a differential diagnosis in patients presenting with symptoms of obstructed defecation.
