T2 Hyperintensity

A 51-year-old man sought care for a 4-month history of generalized seizures. The description of his seizures was consistent with generalized tonic-clonic seizures with focal onset. The patient had no history of head trauma or central nervous system infection and no family history of seizures. The patient reported having visual disturbances for 2 years before the seizures. His medical and surgical history was unremarkable. Brain magnetic resonance imaging showed left temporo-occipital, white matter, T2-signal intensity with gadolinium-enhancing lesions. Brain magnetic resonance imaging showed patchy gadolinium enhancement with T2 hyperintensity in the left parietotemporal and occipital lobes. Brain biopsy of the left temporal lobe showed white matter lesions with necrosis and chronic infiltration with macrophages and CD3-positive T lymphocytes and a predominant perivascular distribution. Focal, secondary vasculitis was present. There was no evidence of lymphoma. A repeated brain biopsy of the parietal lobe after another inflammatory relapse showed pathologic findings identical to the first biopsy. The patient was diagnosed with inflammatory encephalitis without additional defining features on biopsy. The patient received levetiracetam for seizure control, but the seizures remained refractory. He then was treated with high doses of intravenous methylprednisolone and then oral prednisone. Simultaneously, mycophenolate mofetil was initiated. The patient was monitored every 3 months with complete blood cell counts and liver function tests. Three months later, the prednisone dose was slowly tapered. During that process, the patient had no new seizures, and brain magnetic resonance imaging showed no active inflammation. After discontinuation of corticosteroids, the patient had a relapse with a generalized seizure, and brain magnetic resonance imaging showed new gadolinium-enhancing lesions. Prednisone was resumed, with near-remission. He then reinitiated mycophenolate mofetil and continued levetiracetam. With this regimen he remained clinically and radiologically stable, with only occasional visual phenomena that were possibly epileptic, although follow-up electroencephalography when he was symptomatic was normal. Encephalitis of unknown origin represents approximately one-third of cases. This proportion is decreasing over time with the development of novel diagnostic technologies, such as sequencing techniques to identify causative infectious agents and advances in neural autoantibody diagnostics.

The Right

A 45-year-old woman was assessed for slowly progressive gait difficulty. Eight years earlier, she first noticed dragging of her right foot and stumbling on uneven surfaces. She also described difficulty bending the right knee and intermittent spasms of the right leg. She reported bilateral, mild hand weakness when she was doing repetitive tasks such as using scissors. She reported increasing urinary urgency and frequency over the past 3 years. Magnetic resonance imaging of the spinal cord showed continuous, relatively symmetric, T2 hyperintensity of the dorsal columns and, to a lesser extent, the lateral columns, as well as medullary pyramids. Brain magnetic resonance imaging showed T2 hyperintensity in the corticospinal tracts bilaterally extending from the precentral gyrus through the corona radiata and again seen in the pons. Review of the magnetic resonance imaging pattern of white matter abnormalities led to specific clinical suspicion for leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation, an autosomal recessive condition due to DARS2 gene sequence variation. Brain magnetic resonance spectroscopy did not show lactate peaks. Genetic testing findings were abnormal and showed compound heterozygous DARS2 sequence variations. The presence of DARS2 sequence variations confirmed the diagnosis of leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation. The patient was counseled that gradual progression of her gait difficulties could be expected. The following year she reported increasing urinary urgency and several episodes of urge incontinence. She was referred to the urology clinic. Leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation is a leukodystrophy that most commonly presents clinically with spasticity, dorsal column dysfunction, cerebellar ataxia, and sometimes mild cognitive decline. Leukoencephalopathy with brainstem and spinal cord involvement and lactate elevation classically has a childhood onset and therefore may not be included in the differential diagnosis of chronic progressive white matter disease in adults.

Parry Romberg Syndrome

Abstract Background The aim of this study was to: (i) describe the abnormalities seen on brain imaging in a group of children with en coup de sabre (EDCS) with/without Parry-Romberg syndrome (PRS); and (ii) identify clinical predictors of brain imaging abnormalities. Methods This was a single centre (Great Ormond Street Hospital, London) retrospective case series of patients with ECDS/PRS seen from 2000 to 2018. We identified patients with cutaneous manifestations consistent with the clinical descriptions of ECDS/PRS. Presenting clinical, laboratory, and radiological brain findings are described. Results are expressed as medians and ranges or frequencies and percentages. Fisher’s exact test was used to identify clinical associations with magnetic resonance imaging (MRI) abnormalities. Results Fourteen patients were studied: 6 males and 8 females; median age 14 years (range 3–20). We observed neuroimaging abnormalities in 2/6 ECDS and 5/8 ECDS/PRS patients. White matter signal abnormality, dystrophic calcification, leptomeningeal enhancement, and sulcal crowding were the typical findings on brain imaging. A total of 50% of patients had no MRI abnormality despite some of these patients having neurological symptoms. The presence of seizures was significantly associated with ipsilateral enhanced white matter signalling on MRI (p < 0.05). Conclusions In summary, we observed several distinct radiographic patterns associated with ECDS/PRS. Seizure disorder was strongly associated with the presence of ipsilateral enhanced white matter signalling. Improved neuroimaging techniques that combine morphological with functional imaging may improve the detection rate of brain involvement in children with ECDS/PRS in the future.

Cerebral Microbleed

Rationale Cerebral microbleeds seen on brain magnetic resonance imaging are markers of small vessel disease, linked to cognitive dysfunction and increased ischemic and hemorrhagic stroke risk. Observational studies suggest that aspirin use may induce cerebral microbleeds, and associated overt intracranial hemorrhage, but this has not been definitively resolved. Aims ASPREE-NEURO will determine the effect of aspirin on cerebral microbleed development over three years in healthy adults aged 70 years and over, participating in the larger ‘ASPirin in Reducing Events in the Elderly (ASPREE)’ primary prevention study of aspirin. Sample size Five hundred and fifty-nine participants provide 75% power (two-sided p value of 0.05) to determine an average difference of 0.5 cerebral microbleed per person after three years. Methods and design A multi-center, randomized placebo-controlled trial of 100 mg daily aspirin in participants who have brain magnetic resonance imaging at study entry, one and three years after randomization and who undergo cognitive testing at the same time points. Study outcomes The primary outcome is the number of new cerebral microbleeds on magnetic resonance imaging after three years. Secondary outcomes are the number of new cerebral microbleeds after one year, change in volume of white matter hyperintensity, cognitive function, and stroke. Discussion ASPREE-NEURO will resolve whether aspirin affects the presence and number of cerebral microbleeds, their relationship with cognitive performance, and indicate whether consideration of cerebral microbleeds alters the risk-benefit profile of aspirin in primary prevention for older people.
