BACKGROUND Chronic subdural hematoma (CSDH) is a commonly encountered condition in neurological and neurosurgical practice, but the presence of concomitant parkinsonism is extremely rare. Basal ganglia disturbance is a well-known underlying mechanism; however, few cases present with cerebral cortex compression as the cause of symptoms. OBSERVATIONS A 52-year-old man was referred to the authors’ hospital with a 5-week history of gait disturbance and suspected Parkinson’s disease. Neurological examination revealed a mask-like face, stooped posture, left-predominant rigidity, and postural instability. The authors initiated dopamine agonist administration, and brain magnetic resonance imaging (MRI) was scheduled. One week later, MRI showed bilateral CSDHs. The hematomas markedly compressed the bilateral cerebral cortex, whereas the midbrain and basal ganglia structures were intact. The patient underwent burr hole drainage and was discharged after 9 days without sequelae. LESSONS CSDH can cause parkinsonism by compressing the cerebral cortex, which is a part of the cortico–basal ganglia–thalamocortical circuit. Surgery leads to positive outcomes, as illustrated by this case, in which cerebral cortex compression caused parkinsonism.

Background: Dalfampridine extended release (DAL) is a broad-spectrum voltage-gated potassium channel blocker that is indicated in multiple sclerosis to improve the nerve conduction of demyelinated axons. Seizures are a known side effect of DAL, which is contraindicated in patients with a history of epilepsy. Objective: Three cases of multiple sclerosis (MS) with de novo convulsive status epilepticus (CSE) probably related to dalfampridine administration are described. Methods: No patients had a history of seizures or renal impairment. Biological tests were normal. A brain magnetic resonance imaging (MRI) showed diffuse cortical and subcortical atrophy without active inflammatory lesions. Results: All three patients presented with CSE that was attributed to DAL and so was discontinued. Conclusion: These case reports illustrate that, aside from seizures, de novo CSE is a potential complication of MS patients treated with DAL.

Abstract OBJECTIVE Corpora amylacea (CA) normally accumulate within perivascular, subpial, and subependymal astrocytic processes. CA are associated with a number of conditions including normal aging, hippocampal sclerosis associated with temporal lobe epilepsy, multiple sclerosis, Lafora-type progressive myoclonic epilepsy, and adult polyglucosan body disease. Reports of massive localized accumulation of CA in the brain outside of these conditions are rare. CLINICAL PRESENTATION A 49-year-old woman, with a long-standing history of migraine headaches, presented to her primary care provider for increased headache duration. Brain magnetic resonance imaging (MRI) revealed a left parahippocampal lesion, suggestive of low-grade glioma. INTERVENTION Given the MRI suggestive of left parahippocampal glioma, left-sided frontotemporal craniotomy was performed for resection of the lesion. Specimens obtained during the operation revealed focal high-density accumulation of CA with no evidence of neoplasm, ischemia, or hypoxic injury. CONCLUSION This case illustrates the possibility that localized high-density CA accumulation can present as an intrinsic lesion on brain MRI. CA should be included in the differential diagnosis for patients presenting with brain MRI suggestive of nonenhancing space-occupying lesions.

Abstract Background: Among intracranial germinomas, germinoma of basal ganglia has been rarely reported. We discuss a new case of basal ganglia germinoma(BGG) and perform the literature review over the last two decades, with the aim of emphasizing the diagnosis and treatment in early-stage BGG.Case presentation: A seven years old Chinese boy presented with 4 months history of left limb movement disorder and oblique right mouth corner. The human chorionic gonadotropin(HCG) level in cerebrospinal fluid(CSF) was slightly increased. Magnetic resonance imaging(MRI) showed ipsilateral brain and brainstem atrophy. Susceptibility weighted imaging(SWI) revealed obvious hypointensity in right globus pallidus. Pathological diagnosis on biopsy was confirmed with germinoma. The patient had a favorable relief of symptoms after chemoradiotherapy.Conclusion: Intracranial germinoma, a potentially curable tumor, the early diagnosis is essential for the prognosis. An elevated HCG level of CSF or serum can be used as a reference indicator. MRI, especially SWI, plays an important role in early diagnosis. Patients should be treated with standardized chemoradiotherapy early rather than surgery.

Context: Dyke-Davidoff-Masson (DDM) syndrome is a rare neurological condition, first described in 1933. Characteristics include cerebral hemiatrophy, contralateral hemiparesis, seizures, and cognitive dysfunction, combined into different degrees and patterns. Brain magnetic resonance imaging (MRI) is used to perform diagnosis throughout its specific findings. Case Report: A eighteen-year-old female presented to our service with a history of cognitive dysfunction and seizures since early childhood, which persistence even with adequate use of antiepileptic drugs. During Investigation were found signs and symptoms compatible with DDM syndrome, and evidence of pseudoseizures captured in a video electroencephalography monitoring. Conclusion: DDM syndrome is a rare condition that must be part of differential diagnosis in patients with seizures and cerebral hemiatrophy. Management is based on adequate control of seizures and other comorbidities.

A 13-year-old girl presented with a 5-day history of oscillopsia. On examination, ocular flutter and mild cerebellar signs were found. Brain magnetic resonance imaging (MRI) revealed four periventricular and subcortical non-enhancing lesions. Cerebrospinal fluid (CSF) oligoclonal bands were negative. Neuroblastoma or other malignancies were not found. She responded well to a corticosteroid–intravenous immunoglobulin (IVIG) combination and remained symptom-free for 3 years until presenting again with isolated ocular flutter. Brain MRI at this time remained atypical for classic multiple sclerosis (MS) with a predominance of juxtacortical demyelinating lesions. CSF was positive for oligoclonal bands. Serum myelin oligodendrocyte glycoprotein (MOG) antibodies were present. Ocular flutter can be the presenting feature of MOG antibody–associated pediatric demyelination.

ABSTRACT We present a case report of motor and cognitive disorders in a 36-year-old woman with a history of twelve years of heavy alcohol abuse. The patient presented depressive symptoms over the course of one year after a loss in the family, evolving with ataxia, bradykinesia and choreiform movements. Progressive cognitive decline, sleep alterations and myalgia were also reported during the course of disease evolution. Physical examination revealed spastic paraparesis with fixed flexion of the hips and knees with important pain upon extension of these joints. Initial investigation suggested the diagnosis of thiamine deficiency by brain magnetic resonance imaging (MRI).

The revision of MEDLINE from 1966 to 2003 did not report any association between multiple sclerosis (MS) and Melkersson—Rosenthal syndrome (MRS). This is a case report of a 51-year-old woman, with history of four recurrent Bell’s palsies. In 1999 she developed a right facial paralysis due to a supranuclear pyramidal lesion with right monoparesis. The family history showed five relatives with recurrent Bell’s paralysis and plicata tongue. Physical examination: right Bell’s paralysis, left supranuclear facial paralysis, furrowed tongue, right hemiparesis with pallor of the optic disks. Brain magnetic resonance imaging (MRI) demonstrated the typical lesions of MS and CSF oligoclonal bands. This is the first observation of a patient with hereditary MRS and MS. The link between both diseases is discussed.

Background: There are few reported cases of posterior reversible encephalopathy syndrome (PRES) combined with essential thrombocythemia (ET). We report a case of PRES-like syndrome in ET.Case Report: A 60-year-old man with a history of hypertension and thrombocythemia presented with progressive visual loss after waking up; and neurological examination showed pupils were 3 mm and equally reactive to light, which suggested cortical blindness. Brain magnetic resonance imaging (MRI) revealed restricted diffusion in diffusion-weighted imaging (DWI) in the bilateral parietal and occipital lobes. Routine blood tests revealed a platelet count of 1,044 × 109/L. ET was diagnosed after exclusion of other causes. Electroencephalography (EEG) showed periodic triphasic waves in the occipital region. The lesions of the parietal and occipital lobes on MRI and periodic triphasic waves of EEG disappeared quickly, and patient's vision returned to normal after the treatment with hydroxyurea and sodium bicarbonate. The patient experienced hallucinatory palinopsia during the recovery of vision.Conclusion: ET may be a risk factor for PRES.

Hallervorden-Spatz syndrome is a rare neurodegenerative disease, related to mutations in a gene located on chromosome 20p13. Hallervorden-Spatz syndrome is characterized by iron accumulation in the basal ganglia, which leads to variable neurologic manifestations. It is reported the case of a 6 years old male patient, with history of neuro psycho motor development involution noticed since 1 year and 5 months of age and progressive development of dystonia, mostly on upper limbs and neck. Brain Magnetic Resonance Imaging (MRI) revealed bilaterally symmetric signal changes in globus pallidus and in the posterior limb of the internal capsule, findings that suggest neurodegenerative disease with iron accumulation or metabolic disease.

Introduction: Idiopathic intracranial hypertension (IIH), also known as pseudotumor cerebri, is a rare neurological manifestation of coronavirus disease 2019 (COVID-19) infection. Case Presentation: In this case study, we present a 10-year-old girl with headache, diplopia, bilateral sixth nerve palsy, and papilledema following a history of seven days of fever about two weeks ago. In lumbar puncture, the opening pressure was 56 cmH2O. Cerebrospinal fluid analysis was normal. Brain magnetic resonance imaging (MRI) was suggestive of IIH. Nasopharyngeal reverse transcription-polymerase chain reaction (RT-PCR) was positive for COVID-19. Oral acetazolamide was prescribed, and the patient improved completely after three weeks of continuous medical treatment. Conclusions: Since IIH is a rare neurological complication of COVID-19, we have to suspect COVID-19 infection in any patient with IIH.
