Pyramidal Tract Lesion


Presentation

  • Takashi Kageyama, Toshihiko Suenaga Department of Neurology, Tenri Hospital, Tenri, Nara, Japan Correspondence to Dr Kazuto Tsukita, kazusan{at}kuhp.kyoto-u.ac.jp Statistics from Altmetric.com Description An 85-year-old man with type 2 diabetes mellitus presented[casereports.bmj.com]
  • One month later she presented with mild dysarthria and mild left hemiparesis. Brain MRI disclosed an extensive pyramidal tract lesion from the right corona radiata to the pedunculus cerebri.[jstage.jst.go.jp]
  • Design/Methods: Review of clinical presentations and brain MRIs.[neurology.org]
  • Our patient presented with secondary seizures, as previously reported by Hinchey et al. [ 1 ], that resulted in signal changes along the pyramidal tracts.[em-consulte.com]
  • Physiologically, it is normally present in infants from birth to 12 months. The presence of the Babinski sign after 12 months is the sign of a non-specific upper motor neuron lesion.[ipfs.io]

Renal Artery Stenosis
  • There was no evidence of renal artery stenosis or adrenal tumor. Blood pressure was controlled with medication for a period of 6 months, and the patient was also given anticonvulsive therapy.[em-consulte.com]
Asymptomatic
  • The patient was asymptomatic, and his blood pressure stayed within the normal range with medication.[em-consulte.com]
Cheyne-Stokes Respiration
  • Deep anaesthesia Pathological causes of Babinski sign in absence of Pyramidal Tract Lesion Narcotic overdose Alcohol intoxication Following electroconvulsive therapy Coma secondary to metabolic disturbances Post-traumatic states Post-ictal state In Cheyne-Stokes[notes.medicosnotes.com]
Nausea
  • The clinical symptoms associated with RPLS include headache, nausea, vomiting, loss of consciousness, seizures and progressive loss of sight leading to associated cortical blindness [ 1 ].[em-consulte.com]
Hyperreflexia
  • Symptoms include an increase in the muscle tone in the lower extremities, hyperreflexia, positive Babinski and a decrease in fine motor coordination.[sideeffects.embl.de]
  • Interruption of corticospinal fibers rostral to the motor (pyramidal) decussation causes impairment of movement in the opposite body-half, which is especially severe in the arm and leg and is characterized by muscular weakness, spasticity and hyperreflexia[medical-dictionary.thefreedictionary.com]
  • There is hypertonia (increased muscle tone, stiffness), hyperreflexia (exaggerated reflexes), and an oscillatory movement known as clonus.[courses.washington.edu]
  • (Ottawa) Hyperreflexia from Dr.[library.med.utah.edu]
  • On exam there is a combined deficit of vibration and proprioception with pyramidal signs (plantar extension and hyperreflexia).[forums.studentdoctor.net]
Clonus
  • In a patient with clonus, a muscle stretch elicits alternating contractions of agonist and antagonist muscle groups.[courses.washington.edu]
Pyramidal Tract Signs
  • Neurological examination revealed bilateral pyramidal-tract signs, and paresis of the right arm.[em-consulte.com]
Tonic-Clonic Seizure
  • On the way to hospital, he also suffered four episodes of general tonicclonic seizures. He was intubated upon arrival. His neurological examination showed bilateral pyramidal signs.[em-consulte.com]
Generalized Seizure
  • A 38-year-old man was admitted to hospital for loss of consciousness and generalized seizures. His systolic blood pressure was 220 mmHg. Neurological examination revealed bilateral pyramidal-tract signs, and paresis of the right arm.[em-consulte.com]

Treatment

  • It is not intended as a substitute for professional medical advice, diagnosis or treatment.[sideeffects.embl.de]
  • Conclusions: Corticospinal tract lesions have a heterogenous etiology, with widely different treatments and prognoses. An understanding of these potential etiologies will assist neurologists confronted with this imaging finding.[neurology.org]

  • […] doctor will look for signs of a nervous system problem by checking your: Balance and coordination Movement Hearing, speech, and vision Memory and concentration Tests for diagnosis [ edit ] Nerve conduction study Spinal tap or lumbar puncture Nerve biopsy Treatment[en.wikipedia.org]
  • On patient follow-up, MRI signal abnormalities and clinical symptoms were completely resolved after antihypertensive treatment.[em-consulte.com]

Prognosis

  • Patients who have sustained damage to their corticospinal tract have a prognosis that varies, depending on the nature of the damage. Some patients may be able to regain motor control over the course of the healing process.[wisegeek.org]

Etiology

Pathophysiology

Prevention

  • […] hypoglycaemic hemiplegia lesions might be present along the pyramidal tract, since the more compact neuronal tissue might be more vulnerable to hypoglycaemia. 3 The coronal section in this case shows that the lesion is actually along the pyramidal tract and, to prevent[casereports.bmj.com]
