Author reports the case of a 28 years-old woman presenting episodes of paresthesia of the right arm with duration of approximately 4 days which remitted spontaneously, followed after two years by episodes of right hemiparesthesia. Brain MRI followed by brain stereotactic biopsy established the diagnosis of neurocysticercosis. Since electroencephalography showed no spike-wave abnormalities it was difficult to establish if symptoms were secondary to parietal lesion itself or were focal sensory seizures. After treatment with albendazole, methylprednisolone and sodium valproate the patient had a good recovery.

Core Features

Gasperini syndrome (GS), a rare brainstem syndrome, is featured by ipsilateral cranial nerves (CN) V–VIII dysfunction with contralateral hemibody hypoesthesia. While there have been 18 reported cases, the GS definition remains ambiguous. We report a new case and reviewed the clinical features of this syndrome from all published reports to propose a new definition. A 57-year-old man with acute brainstem stroke had right CN V–VIII and XII palsies, left body hypoesthesia and ataxia. Brain MRI showed an acute stroke in the right caudal pons and bilateral cerebellum. After a systematic review, we classified the clinical manifestations into core and associate features based on the frequencies of occurring neurological deficits. We propose that a definitive GS requires the presence of ipsilateral CN VI and VII palsies, plus one or more of the other three core features (ipsilateral CN V, VIII palsies and contralateral hemibody hemihypalgesia). Additionally, GS, similar to Wallenberg’s syndrome, represents a spectrum that can have other associated neurological features. The revised definition presented in this study may enlighten physicians with the immediate recognition of the syndrome and help improve clinical localization of the lesions and its management.

<b><i>Purpose:</i></b> This report describes a case of relapsed primary breast lymphoma (PBL) presenting as vitreoretinal lymphoma (VRL). <b><i>Methods:</i></b> We describe the clinical and hematopathologic findings in a patient with relapsed PBL involving the vitreous of both eyes. <b><i>Results:</i></b> A 59-year-old woman was treated for PBL with systemic and intrathecal chemotherapy 5 years prior to presentation. Three years later, she presented to an outside clinic with blurred vision in both eyes and bilateral vitritis. She was referred to our clinic with concern for ocular lymphoma. On presentation, the patient’s best-corrected visual acuity was 20/40 in the right eye and 20/25 in the left eye with 3+ vitreous cells in the right eye and 2+ vitreous cells in the left eye. Vitreous biopsy of the right eye revealed CD5-negative/CD10-negative B-cell lymphoma cells on flow cytometry. She had no evidence of disease on brain MRI, lumbar puncture, bone marrow biopsy, or full-body CT scans. She was treated with a regimen of rituximab, methotrexate, procarbazine, and vincristine for central nervous system penetration as well as multiple intraocular injections of methotrexate and rituximab with improvement in vision and ocular inflammation bilaterally. <b><i>Conclusion:</i></b> Relapsed PBL can present as bilateral VRL.

Abstract BACKGROUND Low grade gliomas (LGGs) are the most frequent pediatric brain tumor and they comprise a variety of histologies. Complete surgery is curative but sometimes its location makes it difficult. Recent publications highlight the excellent long-term outcomes of patients with LGGs with complete and incomplete resected tumors. Current strategies are focused on reducing risks of treatment related sequelae. METHOD We describe a patient with a suspected LGG managed by close observation. We describe the case of a 6 year old female with 5 months history of focal onset seizures. During this time a brain MRI was requested and tumor was evidenced. After “tumor diagnosis” was made family visited a handful of private neurosurgeons with a uniformly dismal prognosis and high risk morbidity from procedures offered. When first seen at our Hospital, the clinical history seemed compatible with a LGG and seizures well controlled with antiepileptic drugs. Neurological examination was completely normal. MRI showed a large tumor (7x5x5 cm) hypointense on T1, hyperintense on T2, without contrast enhancement, involving the right temporal lobe white matter, insula, internal capsule, hipoccampus, thalamus and mesencephalus with middle cerebral artery encasement. Interval imaging was proposed and after 4.5 years since diagnosis the tumor has been stable and patient clinically excellent. CONCLUSION Overall survival in pediatric LGGs is excellent and risk of sequelae should always be part of multidisciplinary team considerations. In centers with significant neurosurgical morbidity, biopsy of large tumors that are compatible with LGG may not be required in selected cases.

Abstract OBJECTIVE AND IMPORTANCE Schwannomas occurring in the neuraxis are very rare. Usually, these tumors are benign. Primary malignant intracerebral nerve sheath tumors are extremely rare, with only five documented cases in the international literature. We report one case of a primary malignant intracerebral nerve sheath tumor occurring in the right cerebral peduncle of a 35-year-old man. CLINICAL PRESENTATION Magnetic resonance imaging revealed a heterogeneous peripherally enhancing mass of the right cerebral peduncle, surrounded by a small edema. INTERVENTION Unlike the five cases previously reported, this is the first time a stereotactic biopsy has been performed, and this is the only patient who responded to cranial radiation therapy for approximately 2 years. When the tumor recurred, a systemic chemotherapy treatment was prescribed. No positive response was seen, and the patient died 29 months after the initial diagnosis. CONCLUSION An accurate diagnosis and planned aggressive treatment seem to be the key elements in the management of the disease.

Distressing Condition

A 76-year-old man was admitted to the hospital with acute onset of involuntary movements of the left side of his body. His neurological examination revealed he was oriented only to himself, and aforementioned movements of his left arm and leg. CT head demonstrated old infarcts in his right aspect of his pons and basal ganglia. Cerebrospinal fluid analysis was unremarkable. He initially had a normal blood glucose with an elevated anion gap and elevated creatine kinase. Brain MRI showed a small lacunar-type ischaemic infarct within the anteromedial aspect of the right cerebral peduncle, which localised to his haemiballism. To prevent worsening rhabdomyolysis associated with his haemiballism, the primary team initiated both tetrabenazine and diazepam. His movements improved after 1 week of medication therapy. This report discusses a thorough workup for this movement disorder and when to intervene for this distressing condition.

Early Manifestation

Parkinsonism in SLE is rare. Diffuse leukoencephalopathy is equally uncommon and is associated with a poor prognosis. We present a single case of a 50-year-old Filipino man who presented with a generalized discoid rash after starting lisinopril. The rash persisted despite discontinuation of lisinopril, and over the next three months, he developed rapidly progressive parkinsonism. Brain MRI showed symmetric confluent T2-hyperintensities involving the white matter and basal ganglia. Four of the 11 American College of Rheumatology criteria for the classification of SLE were met. A rheumatologist made a diagnosis of SLE with cutaneous and central nervous system involvement. Significant neurologic and radiologic improvement occurred following treatment with IV steroids followed by a prolonged taper. This report highlights a case of subacute parkinsonism with a diffuse leukoencephalopathy as an early manifestation of SLE which resulted in a good recovery following treatment with only immunosuppressive therapy.

Arterial Diameters

Introduction: Brain perivascular spaces (PVS) are associated with higher pulse pressures and may be imaging biomarkers of systemic arterial stiffness. We hypothesized that larger proximal arterial diameters act as effect modifiers between downstream PVS and surrogate measures of arterial stiffness. Methods: Stroke-free Northern Manhattan Study participants with brain MRI and carotid ultrasound were analyzed. Perivascular spaces were rated semi-quantitatively as ≤ 3 mm voids on axial T1 images without associated FLAIR hyperintensities. Intracranial brain arterial diameters were measured on MRA. The right common carotid artery (CCA) was assessed by high resolution B-mode ultrasound to obtain systolic and diastolic diameters. CCA stiffness was calculated as a ratio between log n transformed systolic-diastolic blood pressure and (systolic - diastolic diameter)/diastolic diameter. We created generalized linear models using and pulse pressure (PP) and CCA stiffness as predictors as independent variables and right anterior PVS score as the outcome, adjusting for demographics, risk factors, head size. Results: Among 941 participants (N=941, mean age 71 ± 9 year, 60% women, 66% Hispanic), PP was associated with PVS score (B=0.003, P=0.04) in an adjusted model. There was a statistical interaction between PP, right CCA diastolic diameter, and right intracranial arterial diameters as predictors of right anterior PVS score (P=0.03), but this interaction was not significant for posterior fossa PVS score (B=0.015, P=0.191), or when substituting right intracranial arterial diameters with the basilar artery diameter (B=-0.004, P=0.191). The association between PP (P=0.003) or carotid stiffness (P=0.002) with right anterior PVS score was greater among participants with larger right intracranial arterial and larger CCA diameters. Conclusions: Arterial stiffness is related to downstream PVS in those with larger proximal arterial diameters. These results suggest a mechanical effect of pulsatility on brain parenchyma and further studies are needed to enhance our understanding of the link between systemic hemodynamics and brain diseases such as dementia and stroke.

Although pediatric myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease is increasingly well-recognized, its full clinical spectrum is still being defined. Cortical encephalitis is emerging as a distinct clinico-radiologic syndrome of adult MOG antibody-associated disease. We describe a 12-year-old girl who presented with new onset seizures and left-sided hemiparesis. Brain MRI showed edema of the right temporal-parietal-occipital cortex with associated focal leptomeningeal enhancement. Patient received high-dose corticosteroids and 21 days of acyclovir despite negative infectious work-up due to the focal nature of encephalitis. Patient remained seizure-free for 20 months before presenting with new right hemiclonic seizures with right-sided hemiparesis and edema of the left temporal-parietal cortex with associated leptomeningeal enhancement. Patient’s MOG antibody titer was 1:40. She completed high-dose corticosteroids and intravenous immunoglobulin. Our patient highlights the importance of MOG antibody testing in pediatric focal cortical encephalitis to avoid unnecessary anti-viral agents and provide more appropriate immunotherapy and a more informed prognosis.

Objective:To describe a rare sign of unilateral brain injury as a form of unwanted blink-associated contralateral eccentric saccades.Methods:A 62-year-old patient who underwent an ischemic stroke affecting the entire right middle cerebral artery territory came to our attention 1 year after stroke, manifesting with transient contralateral conjugate gaze deviations associated with spontaneous blinking. We complemented the regular neurologic evaluation with brain MRI, study of evoked potentials, electroneurography of the facial nerve, and infrared video-oculoscopy.Results:The patient had left-sided hemiparesis, hypoesthesia, hemianopia, and hemispatial neglect. He also showed the occurrence of a rapid leftward conjugate deviation of the eyes, followed by a corrective movement to the primary ocular position. MRI showed a wide malacic area spanning the right frontal, temporal, and parietal cortical and subcortical regions, with signs of wallerian degeneration of the descending right corticospinal tract. Motor and somatosensory evoked potentials were centrally altered on the right side. Electroneurography of the facial nerves was normal. Infrared video-oculoscopy indicated persistence of the same blink-related saccades even in darkness.Conclusions:It is known that unilateral cerebral lesions may manifest with a contralateral conjugate gaze deviation evoked by closure of the lids. This sign, known as spasticity of conjugate gaze, may be due to the suppression of the fixation reflex. In our case, the persistence of this sign in the darkness allowed us to exclude this diagnosis. We hypothesized that the blink-related neural pathways may improperly activate the oculomotor circuitry at both the cortical and subcortical levels.

Abstract Meningioma is in most cases a benign tumor of the central nervous system with two growth patterns: en masse and en plaque. Hyperostosis is associated in 13 - 49 % of the cases with en plaque meningioma. We describe the case of a 47 years old woman with meningotelial sphenoid ridge meningioma which was totally removed. At the first admission she presented with no neurological deficits, seizures and a mild right exophthalmos. This had an indolent growth. After 10 years, the patient was readmitted for headache, blurred vision and right exophthalmos. Skull X-rays and brain MRI revealed an important thickening of the right superior orbit wall and sphenoid ridge. She underwent a new surgery. There was no intradural tumor found. Instead, bones of the superior and lateral right orbit walls were very hiperostotic. A hole of 3/2 cm in the right superior orbital wall was drilled and the orbital cavity was decompressed. In the postoperative period, the symptoms were remitted and the exophthalmos reduced. We discuss the causes and management of hyperostosis associated with meningiomas.
