The coexistence of spinal teratoma of the conus medullaris and arteriovenous malformation (AVM) is exceptional, which has not been reported previously in the literature. The precise mechanism of the coexistence of these conditions is not known, however, the dysembryonic origin of spinal cord teratoma and AVM seems to play a part in this process. A 34-year-old male patient was admitted with lowe...

PURPOSE To establish the normal range of the position of the conus medullaris in neonates and determine whether it differs from that in adults. METHODS One hundred five healthy neonates born over an 18-day period in a single obstetric unit had ultrasound examinations of their lower spines to relate the conus medullaris to the nearest intervertebral disk or midvertebral level. RESULTS The me...

PURPOSE To determine the appearance of the ventriculus terminalis of the conus medullaris and the frequency with which it is seen on MR. METHODS Four hundred eighteen normal spine MR examinations were reviewed. RESULTS Eleven (2.6%) of 418 children, all younger than 5 years of age, demonstrated an ovoid, nonenhancing, smooth dilation of the central canal within the conus medullaris. Average...

Background and Importance: Conus medullaris dermoid cysts are benign lesions, usually observed in the lumbosacral region of ​​ the spinal canal. Such lesions are often associated with congenital dermal sinus tracts and spinal dysraphism. Case Presentation: We reported a 37-year-old man with progressive paralysis in left lower limb distal presented to our clinic. The MRI of the lumbar spine, as...

We describe a case of spinal leptomeningeal metastases of an astrocytoma of the conus medullaris that presented with quadriplegia. The patient was a 50-year-old woman with a previously treated astrocytoma of the conus medullaris and a spinal cord metastasis at the Th2-L level. Four years after the initial treatment, the patient developed weakness of the upper extremities with a decreased muscul...

BACKGROUND Given the risk of paralysis associated with cervical transforaminal injection, is it time to reconsider transforaminal injections of the lumbar spine? Arguments for discontinuing lumbar injections have been discussed in the anesthesia literature, raising concern about the risks of epidural steroid injections (ESIs). METHODS In a 47-year-old man, paraplegia of the lower extremities ...

A 41-year-old woman originally from West Africa presented with a 3-week history of generalized weakness. Clinical examination demonstrated quadriparesis, urinary incontinence, and reduced level of consciousness. The imaging of the neuraxis revealed multiple bilateral cerebral lesions, including basal ganglia and midbrain. Spinal cord imaging showed lesions in the conus medullaris (figure). The ...

This retrospective study was designed to determine the location of the conus medullaris in normal children by reviewing a series of MR images of the lumbar spine. The study group consisted of 184 children ranging in age from newborn to 20 years who had a normal conus level as reported by the radiologist of record. The range of conus levels for the entire group of normal children was T12 to L3. ...
