“…Histopathological examination after resection was, however, compatible with MPE. On the other hand, Thoriya et al [18] reported a case of primary PNET of lumbosacral spine in a 31-year-old female with a 4 week history of progressive low back pain and weakness of lower limbs, which was primarily diagnosed as MPE based on MRI findings.…”

Abstract:Introduction: Myxopapillary ependymoma (MPE) is a benign and slow growing tumor that originates exclusively from the conus medullaris and cauda equina nervous tissue. It occurs more commonly in young patients. In addition, clinical presentations are non-specific and may mimic benign conditions. Magnetic resonance imaging (MRI) is the imaging modality of choice for evaluating this tumor. We hereby report on two young patients with long-lasting non-specific symptoms, which were clinically attributed to benign conditions. However, cauda equina tumor was revealed on MRI in both patients. Case report: Two cases of cauda equina MPE, a 19-year-old female and a 38-year-old male, with different clinical manifestations are reported. The first patient presented with paresis and paresthesia of the lower limbs, and the second patient's complaint was chronic low-back pain and urinary incontinence. In both cases, MRI detected a tumor originated from the cauda equina, and histopathologic examination was compatible with MPE. Conclusion: Cauda equina tumors should be considered as a differential diagnosis in the young patients presented with neurologic deficits in the lower limbs, sphincter or erectile dysfunction, and even a simple low-back pain (particularly when symptoms are long-lasting and/or progressive).
