background:   many of the patients with tethered cord syndrome (tcs) are admitted because of neurological symptoms, while some are admitted because of their orthopedic, urologic, anorectal, and dermatologic manifestations.consequently, this study aimed to evaluate the importance of early diagnosis and treatment of tethered cord syndrome on patient outcome. methods: fourty-three patients who und...

BACKGROUND/AIMS An occult tight filum terminale syndrome has been described wherein clinical symptoms result from tension on the spinal cord despite nondiagnostic spinal magnetic resonance imaging (MRI). Recent reports have suggested a role for surgical untethering in this patient population; however, controversy remains regarding the surgical treatment of this condition. Owing to the various c...

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...

MR examinations of the spine were reviewed in 25 patients with a clinical diagnosis of tethered spinal cord. In 21 patients (84%), the level of the tip of the conus was below the mid L2 vertebral body. The causes of the tethering were spinal lipomas (72%), tight filum terminale syndrome (12%), diastematomyelia (8%), and myelomeningocele (8%). These entities were readily identified in all instan...
