Magnetic resonance imaging in infections of the brain: findings in tuberculosis, listeriosis, toxoplasmosis, subacute sclerosing panencephalitis, and…

1987

A total of 6 patients with various inflammatory brain diseases were investigated by MRI. Typical diagnostic criteria like signal intensity, location, and morphology of the lesions are presented. MRI proves to be a highly sensitive method to detect encephalitic foci, which, however, suffers from a low specificity. Therefore additional informations like case history, clinical findings, and serological data have to be considered to find the correct diagnosis.

Amphotericin B Penetrates into the Central Nervous System through Focal Disruption of the Blood-Brain Barrier in Experimental Hematogenous Candida Me…

2019

Hematogenous Candida meningoencephalitis (HCME) is a life-threatening complication of neonates and immunocompromised children. Amphotericin B (AmB) shows poor permeability and low cerebrospinal fluid (CSF) concentrations, but is effective in treatment of HCME. In order to better understand the mechanism of CNS penetration of AmB, we hypothesized that AmB may achieve focally higher concentrations in infected CNS lesions. An in vitro BBB model was serially infected with C. albicans. Liposomal AmB (LAMB) or deoxycholate AmB (DAMB) at 5 μg/ml were then provided, vascular and CNS compartments were sampled 4h later. For in vivo correlation, rabbits with experimental HCME received a single dose of…

Unexpected postmortem diagnosis of Acanthamoeba meningoencephalitis following allogeneic peripheral blood stem cell transplantation.

2008

Meningoencephalitis caused by pathogenic free-living amebas is usually fatal. Only a few cases of Acanthamoeba meningoencephalitis, diagnosed at autopsy, have been reported following hematopoietic stem cell transplantation. We here report a case of Acanthamoeba meningoencephalitis following allogeneic peripheral blood stem cell transplantation with rapidly evolving neurologic symptoms that remained unexplained. Magnetic resonance imaging failed to show brain lesions and cerebrospinal fluid was negative for microbiological cultures. Definite diagnosis was an unexpected autopsy finding. As overall and teaching hospital autopsy rates are declining worldwide, we must emphasize the need of autop…

Atypical presentation of anti-N-methyl-D-aspartate receptor encephalitis: two case reports

2017

Abstract Background Anti-N-methyl-D-aspartate receptor encephalitis is a rare autoimmune disease characterized by severe neurological and psychiatric symptoms and a difficult diagnosis. The disease is often secondary to a neoplastic lesion, seldom diagnosed years later. Psychiatric symptoms are prevalent in adults; neurologic symptoms are more evident in children, who typically present primarily with neurological symptoms. To the best of our knowledge, the association with juvenile idiopathic arthritis has not been described. Case presentation We report the cases of two caucasian girls with an atypical presentation. The first patient was an 8-year-old girl with normal psychomotor developmen…

Neurological complications in pediatric patients with SARS-CoV-2 infection: a systematic review of the literature

2021

Abstract Objectives To describe clinical characteristics, laboratory tests, radiological data and outcome of pediatric cases with SARS-CoV-2 infection complicated by neurological involvement. Study design A computerized search was conducted using PubMed. An article was considered eligible if it reported data on pediatric patient(s) with neurological involvement related to SARS-CoV-2 infection. We also described a case of an acute disseminated encephalomyelitis (ADEM) in a 5-year-old girl with SARS-CoV-2 infection: this case was also included in the systematic review. Results Forty-four articles reporting 59 cases of neurological manifestations in pediatric patients were included in our revi…

Features in tubercular meningoencephalitis diagnosis: 18 childhood cases

2008

The aim of this research is to illustrate clinical and instrumental features of central nervous system tuberculosis (CNS-TB) in childhood in order to allow prompt diagnosis and adequate patient management. TB remains one of the most important communicable diseases and represents a major global health problem. Although pulmonary TB tends to be the most common form of the disease, the highest mortality and morbidity occurs with TB of the central nervous system (CNS-TB), which develops in 4% of children with tuberculosis. It has a high fatality rate and causes serious sequelae, especially during childhood. CT and MR imaging studies of 18 patients (11 female, 7 male, mean age 45.72 months) were…

Opsoclonus-myoclonus syndrome attributable to West Nile encephalitis: a case report

2014

Introduction Opsoclonus-myoclonus syndrome is a very rare neurological disorder associated with some viral infections and exceptionally with the West Nile virus. Case presentation A 57-year-old Caucasian woman presented with fever, dizziness, balance difficulties, vomiting, dancing eye, altered speech, tremor, generalized myoclonus and failure to rise or stand. Our objective is to describe a patient with West Nile infection, which was identified both in her serum and cerebrospinal fluid and was associated with encephalitis and opsoclonus-myoclonus-ataxia syndrome. Conclusions Opsoclonus-myoclonus-ataxia syndrome continued for 4 weeks after onset, when she died. There was no evidence for any…

Paraneoplastische limbische Enzephalitis bei kleinzelligem Bronchialkarzinom

2004

We report about a 63-year-old male patient who complained of a recent onset of confusion. A mediastinal mass had been detected in his chest X-ray three days before admission to our clinic. Surprisingly, a CT scan of the brain revealed no signs of cerebral masses or oedema. MRI demonstrated bright hyperintens signals in the medial aspect of both temporal lobes. Biopsy by mediastinoscopy showed small cell lung carcinoma (SCLC). No distant metastases were found by staging procedures. Cerebrospinal fluid and serum contained antineuronal antibodies (anti-Hu). The combination of symptoms, MRI findings and paraneoplastic antibodies established the diagnosis of paraneoplastic limbic encephalitis in…

Concurrent staphylococcal and herpes simplex infections – diagnostic pitfalls. A case report

2018

We describe the case of a six-year-old boy with concurrent staphylococcal septicaemia, herpes simplex virus encephalitis (HSVE), and haemorrhagic erosive oesophagitis. Due to guiding clinical and lab symptoms that suggested a diagnosis of staphylococcal sepsis with central nervous system (CNS) involvement, acyclovir treatment was discontinued a"er three days, but the lack of progress in neurological status, further lab tests, and CT and MRI imaging led the authors to consider possible HSV infection, and this diagnosis was con#rmed by PCR test. Even though the treatment for HSV was applied again, the long gap in acyclovir medication contributed to a severe neurological de#cit and an adverse …
