For those children with spinal cord diseases, lumbar puncture may damage the spinal cord due to possibility of tethered spinal cord syndrome where the spinal cord is located below than the usual spinal termination level. [3] Therefore, lumbar puncture should be done at the lowest position as possible for such cases. However, spinal cord injury ...
Sagittal CT of the lumbar spine showing Baastrup's sign. The salient feature of the disorder is the exuberant osteophytosis that occurs at posterior lumbar spinous processes. Osteophytes are coarse calcifications at the edges of bone that form due to repetitive stress and trauma.
Intraoperative neurophysiological monitoring (IONM) or intraoperative neuromonitoring is the use of electrophysiological methods such as electroencephalography (EEG), electromyography (EMG), and evoked potentials to monitor the functional integrity of certain neural structures (e.g., nerves, spinal cord and parts of the brain) during surgery.
Lumbosacral transitional vertebrae consist of the process of the last lumbar vertebra fusing with the first sacral segment. [1] While only around 10 percent of adults have a spinal abnormality due to genetics, a sixth lumbar vertebra is one of the more common abnormalities. [2] Sacralization of the L5 vertebra is seen at the lower right of the ...
MRI of the lumbar spine showing spinal stenosis. Neurogenic claudication is one subtype of the clinical syndrome of lumbar spinal stenosis (LSS). [9] No gold standard diagnostic criteria currently exist, but evaluation and diagnosis is generally based on the patient history, physical exam, and medical imaging. [1]
Congenital dermal sinus is an uncommon form of cranial or spinal dysraphism. [2] [3] It occurs in 1 in 2500 live births. [3]It occurs as a dermal indentation, found along the midline of the neuraxis and often presents alongside infection and neurological deficit. [2]
The former first lady was notably absent from President Jimmy Carter's state funeral service, leading Barack Obama and Donald Trump to be seated next to one another
Enostosis is usually found in T1 to T7 for the thoracic spine and L2 to L3 in the lumbar spine. It consists of cortical bone merging with medullary bone with irregular margins. The shape of the lesion is round or oval with a thornlike margin, up to 2 cm in diameter. In both T1 and T2-weighted imaging, it shows low signal intensity.
