Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem. The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery . [ 1 ]
A disrupted blood supply to posterior inferior cerebellar artery due to a thrombus or embolus can result in a stroke and lead to lateral medullary syndrome. Severe occlusion of this artery or to vertebral arteries could lead to Horner's Syndrome as well.
Lateral medullary syndrome, also known as Wallenberg's syndrome, is caused by blockage of the posterior inferior cerebellar artery (PICA) or the vertebral arteries. Signs and symptoms include decreased pain and temperature on the same side of the face and opposite side of the body compared to the lesion, ataxia on the same side of the lesion ...
Babinski–Nageotte syndrome is an alternating brainstem syndrome. It occurs when there is damage to the dorsolateral or posterior lateral medulla oblongata, likely syphilitic in origin. [1] Hence it is also called the alternating medulla oblongata syndrome. [clarification needed] The medulla oblongata is the lower half of the brainstem.
Bertolotti's syndrome is characterized by sacralization of the lowest lumbar vertebral body and lumbarization of the uppermost sacral segment. It involves a total or partial unilateral or bilateral fusion of the transverse process of the lowest lumbar vertebra to the sacrum, leading to the formation of a transitional 5th lumbar vertebra.
The conus medullaris (Latin for "medullary cone") or conus terminalis is the tapered, lower end of the spinal cord. It occurs near lumbar vertebral levels 1 (L1) and 2 (L2), occasionally lower. [1] [2] The upper end of the conus medullaris is usually not well defined, however, its corresponding spinal cord segments are usually S1–S5.
Only the nucleus ruber and the dentate nucleus are shown in this diagram; the olivary nucleus is positioned on the lateral aspect of the brainstem. Palatal myoclonus The myoclonic triangle (also known by its eponym Triangle of Guillain-Mollaret or dentato-rubro-olivary pathway ) is an important feedback circuit of the brainstem and deep ...
The lateral corticospinal tract (also called the crossed pyramidal tract or lateral cerebrospinal fasciculus) is the largest part of the corticospinal tract.It extends throughout the entire length of the spinal cord, and on transverse section appears as an oval area in front of the posterior column and medial to the posterior spinocerebellar tract.
