Sacral chordoma: an unusual cause of neurogenic bladder - a case report.

Abstract

A 67-year-old man had severe dysuria associated with erectile dysfunction. On digital rectal examination, we palpated a mass protruding through the posterior wall of the rectum. The gluteal region is infiltrated by a firm mass. MRI revealed an osteolytic sacral tumor. A percutaneous biopsy of the tumor was performed. A pathological examination confirmed the diagnosis of sacral chordoma. The patient had palliative radiotherapy. One year after radiotherapy, he had rectal stenosis associated with severe constipation. Sacral chordoma is a rare malignant tumor. Sacralgia is the most common sign. LUTS and erectile dysfunction were rarely reported in patients affected by this bone tumor. MRI is very suggestive of this pathology. Diagnostic confirmation requires pathological examination. The curative management consists of a large resection of the tumor. For inextricable tumors, palliative radiotherapy can be carried out. The prognosis of sacral chordoma is defined by a high recurrence potential and a low metastatic risk. Sacral chordoma is a rare bone tumor. It is an unusual cause for LUTS and erectile dysfunction. Complete tumor excision is the only curative treatment. Recurrence after treatment is the main challenge for surgeons.
