AbstractCerebellar hemorrhage is rare in term newborns and is most often seen after traumatic birth. Lifelong sequelae include motor and cognitive impairment. We report the uncommon case of a late preterm infant born by spontaneous delivery who showed right peripheral facial palsy at 24 hours of life. Cranial ultrasound showed lateral ventricles dilatation and a diffuse hyperechoic round lesion in the right cerebellar hemisphere. The computed tomography scan confirmed a hemorrhagic lesion in the right cerebellar hemisphere and in the vermis with midline shift and intraventricular bleeding. Ommaya reservoir was inserted and used for a few days. The facial palsy gradually recovered to a complete remission after 6 weeks. Follow-up examinations at 12 and 18 months evidenced infant's delayed motor function, hyperreflexia, tremors, and speech delay.

Objective: To report 4 different neurological complications of H1N1 virus vaccination. Method: Four patients (9, 16, 37 and 69 years of age) had neurological symptoms (intracranial hypertension, ataxia, left peripheral facial palsy of abrupt onset, altered mental status, myelitis) starting 4-15 days after H1N1 vaccination. MRI was obtained during the acute period. Results: One patient with high T2 signal in the cerebellum interpreted as acute cerebellitis; another, with left facial palsy, showed contrast enhancement within both internal auditory canals was present, however it was more important in the right side; one patient showed gyriform hyperintensities on FLAIR with sulcal effacement in the right fronto-parietal region; and the last one showed findings compatible with thoracic myelitis. Conclusion: H1N1 vaccination can result in important neurological complications probably secondary to post-vaccination inflammation. MRI detected abnormalities in all patients.

Abstract Background Isolated peripheral facial palsy (P-FP) can lead to lesions involving the inferomedial tegmentum of the pons. However, cases with P-FP in result of a medullary lesion have rarely been reported and result from a paraventricular lesion have never been reported before. Cases presentation We described a 63-year-old man presenting with isolated P-FP due to ipsilateral pontomedullary infarction. Brain diffusion MRI revealed a hyper-intense signal on the left dorsolateral portion of the upper medulla and pontomedullary junction. And then we experienced a 77-year-old man presenting with lateral paraventricular infarction who showed contralateral peripheral type facial palsy. Brain diffusion-weighted image(DWI) showed a high-signal intensity lesion in the right lateral paraventricule and part of the posterior limb of the right internal capsule. Conclusions These two cases caution that a central nervous etiology should be considered in patients with P-FP, especially if they have high risk factors of cerebral infarction.

AbstractThe Ramsay Hunt's syndrome (RHS), caused by the reactivation of the varicella-zoster virus (VZV), is an infrequent cause of peripheral facial palsy in the pediatric patients. A 16-year-old adolescent boy presented with headache, right earache, and signs of lower motor neuron type facial palsy. He was medicated with deflazacort. Four days later, he developed blurry vision in the right eye, gait imbalance, and vesicular lesions in the right ear with decreased ipsilateral hearing acuity. A diagnosis of RHS was considered. Cerebrospinal fluid (CSF) analysis showed pleocytosis, as well as VZV DNA. Magnetic resonance imaging of the brain identified abnormal uptake of gadolinium contrast in the right seventh cranial nerve, reinforcing the diagnosis. The patient was treated with acyclovir (14 days) and prednisone, with progressive clinical improvement. We emphasize the importance of recognizing this syndrome in patients with facial palsy, since the early antiviral treatment significantly improves the prognosis.

The execution of voluntary muscular activity is controlled by the primary motor cortex, together with the cerebellum and basal ganglia. The synchronization of neural activity in the intracortical network is crucial for the regulation of movements. In certain motor diseases, such as dystonia, this synchrony can be altered in any node of the cerebello-cortical network. Questions remain about how the cerebellum influences the motor cortex and interhemispheric communication. This research aims to study the interhemispheric cortical communication between the motor cortices during dystonia, a neurological movement syndrome consisting of sustained or repetitive involuntary muscle contractions. We pharmacologically induced lateralized dystonia to adult male albino mice by administering low doses of kainic acid on the left cerebellar hemisphere. Using electrocorticography and electromyography, we investigated the power spectral densities, cortico-muscular, and interhemispheric coherence between the right and left motor cortices, before and during dystonia, for five consecutive days. Mice displayed lateralized abnormal motor signs, a reduced general locomotor activity, and a high score of dystonia. The results showed a progressive interhemispheric coherence decrease in low-frequency bands (delta, theta, beta) during the first 3 days. The cortico-muscular coherence of the affected side had a significant increase in gamma bands on days 3 and 4. In conclusion, lateralized cerebellar dysfunction during dystonia was associated with a loss of connectivity in the motor cortices, suggesting a possible cortical compensation to the initial disturbances induced by cerebellar left hemisphere kainate activation by blocking the propagation of abnormal oscillations to the healthy hemisphere. However, the cerebellum is part of several overly complex circuits, therefore other mechanisms can still be involved in this phenomenon.

Radiologic Features

Background: Gliosarcomas are rare tumors with mixed glial and mesenchymal components. Many of their radiologic features resemble those of other primary brain malignancies. Purpose: To investigate the magnetic resonance (MR) imaging features of gliosarcomas. Material and Methods: We retrospectively reviewed the MR images, pathology reports, and clinical information of 11 male and four female patients aged 15–71 years to evaluate the location, morphology, enhancement, and other features of their pathologically confirmed gliosarcomas. Results: Apart from one tumor in the right cerebellar hemisphere, all were supratentorial. Two tumors were intraventricular, and four involved the corpus callosum. The tumors were well demarcated, with an inhomogeneous or cystic appearance and moderate-to-extensive surrounding edema. Thick walls with strong rim and ring-like enhancement were observed in 13 (87%). Seven (47%) showed intratumoral paliform enhancement. Conclusion: Gliosarcoma demonstrates certain characteristic MR features, such as supratentorial and peripheral location, well-demarcated, abutting a dural surface, uneven and thick-walled rim-like or ring enhancement, as well as intratumoral strip enhancement. These findings, combined with patient age, can aid the differential diagnosis of gliosarcomas from more common primary brain tumors.

Idiopathic Facial Palsy

AbstractFacial nerve paralysis is a common otolaryngological diagnosis. Recurrent unilateral peripheral facial palsy is found in about 7 per cent of the cases. Simultaneous bilateral facial palsy is relatively uncommon and occurs in 0.3–2.0 per cent of cases of facial palsy. Recurrent. simultaneous, bilateral, idiopathic facial palsy to the best of our knowledge has never been reported. A case of recurrent, simultaneous, bilateral, idiopathic facial palsy is presented. No evidence of systemic or local disease was found in both attacks of peripheral facial palsies. The association with states of stress is the only common finding between the two attacks.
