MR findings of decerebrate rigidity with preservation of consciousness.
نویسندگان
چکیده
We describe a case of decerebrate rigidity, with preservation of consciousness, caused by a discrete pontine tegmentum lesion identified on MR imaging. Lesions within a certain brain stem region are responsible for decerebrate rigidity in animal studies, but there has been a lack of MR imaging evidence in humans. This report also implies that a discrete lesion was responsible for the decerebrate rigidity, while consciousness was preserved.

Preserved motor-evoked potentials but without good motor recovery in a patient with decerebrate rigidity.
The corticospinal tract is not incriminated in decerebrate rigidity (DR). However, this has not yet been proven in humans. We applied transcranial magnetic stimulation (TMS) in a decerebrate patient to support the hypothesis. A patient suffering from pontine hemorrhage with the fourth ventricular extension was admitted unconscious and in a decerebrate posture. Five days later, she regained cons...
متن کاملRadiologic and Clinical Findings in Tuberculous Meningitis
We aimed to evaluate the radiologic and clinical findings of patients with tuberculous meningitis encountered during a 4-year period, retrospectively. Sixteen patients with tuberculous meningitis were admitted to our hospital. The diagnosis was based on abnormal neurologic symptoms and signs, cerebrospinal fluid findings, negative bacteria culture, and abnormalities on brain-imaging studies. CT...
متن کاملAutoerotic nonlethal filmed hangings: a case series and comments on the estimation of the time to irreversibility in hanging.
Recent studies of filmed hangings have documented the agonic sequences in these deaths. Considering this agonic sequence, one question comes to mind: which of these responses is an indicator of irreversible damage? Since decerebrate rigidity points toward lesions of the midbrain, it was initially thought that this posture could be an indicator of severe potentially irreversible damage. However,...
متن کاملPharmacology of oxazolidinones in rat decerebrate rigidity, with reference to their glutamate blocking action.
A newly synthesized compound, 5-[N-benzyl-N-(3piperidinopropyl)]amino3-phenylisoxazole (MLV208) (Fig. I) has a powerful inhibitory action on the glutamate response at the crayfish neuromuscular junction (NMJ) where glutamate is thought to be an excitatory neurotransmitter. In addition, MLV-208 has an inhibitory action on anaemic decerebrate rigidity in rats and drug-induced tremor in mice (Shin...
متن کاملThe quadriceps stretch reflex in human spasticity.
The similarity of decerebrate rigidity in the cat and human spasticity has been noted frequently since the initial observation of Sherrington (1897). Walshe (1919, 1929) considered the two conditions to be physiologically identical, although spasticity 'is but a fractional expression of decerebrate rigidity'. More recently Brodal (1962) and Rushworth (1964) have referred to this similarity. Bro...
