BACKGROUND We report a rare case of aneurysmal dilatation of filum terminale artery after resection of filum terminal myxopapillary ependymoma. CASE DESCRIPTION The authors report a rare aneurysmal dilatation of the filum terminale artery following removal of a filum terminal myxopapillary ependymoma in a 10-year-old male. The patient presented with 6-month history of increasing back pain wit...

A 30-year-old man presented with an intradural spinal teratoma with thickened filum terminale manifesting as urinary and sexual disturbances, and low back pain persisting for 4 years. Spinal magnetic resonance imaging revealed thickened filum terminale containing a heterogeneously enhanced intradural lesion extending from the L-3 to L-4 levels and in contact with the conus medullaris. The filum...

DOI: 10.1590/S1679-45082017AI3882 A 36-year-old woman with a sudden history of low back pain radiating into the right lower extremity. The physical examination revealed paraparesis, saddle anesthesia and urinary incontinence. Magnetic resonance imaging revealed lipoma of the filum terminale (hyperintense sign within the filum terminale) (Figure 1). The patient underwent surgery without delay wi...

Solitary fibrous tumor (SFT) is a mesenchymal neoplasm that most commonly arises from the visceral or parietal pleura. Solitary fibrous tumor with a primary site in the filum terminale has not been reported previously in the literature. Here we report a case of SFT occurring in the filum terminale. The characteristic imaging feature of this tumor is hypointensity on T2-weighted images. Even tho...

Male 29 years, treated surgically for a traumatic fracture of L2, was referred to us about a year after for the onset of worsening paraparesis, anesthesia in his left arm and trunk, urgent incontinence, hyperhydrosis. An MRI of the spinal cord showed the presence of a holocord syrinx, extending to the filum terminale. The patient underwent surgery via L2 laminectomy, with lysis of the arachnoid...

The filum terminale is an anatomic structure at the end of the spinal cord. Only a few cases of AVFs of the filum terminale have been reported. These AVFs usually consist of a single communication between the anterior spinal artery and a single draining vein. We retrospectively analyzed the clinical and radiologic features and treatment of 4 patients with spinal AVFs of the filum terminale. Cli...

INTRODUCTION Paragangliomas of filum terminale are rare benign tumors, arising from the adrenal medulla or extra-adrenal paraganglia. These lesions usually present with chronic back pain and radiculopathy and only two cases of acute neurological deficit have been reported in literature. PRESENTATION OF CASE A case with an acute paraplegia and cauda equina syndrome due to an hemorrhagic paraga...

We report a 41-year-old man who presented with low back pain, lower extremity paresthesia, urinary retention and constipation. Magnetic resonance imaging showed a vascular intradural-extramedullary lesion at the second lumbar vertebral level. His medical history revealed that he had undergone surgery for a cerebellar hemangioblastoma 5 years ago. The patient underwent a spinal operation and a v...

intradural tumors (WHO grade I) that characteristically occur in the conus medullaris/filum terminale region. They are slow growing tumors with a good prognosis and long-term survival.1 We report a rare case of double MPE occurring at both extremities of the filum terminale. In the light of the present case and an extensive review of the literature, we summarize the imaging characteristics and ...
