Epstein Barr virus (EBV) encephalitis is rare in children but can have severe neurological complications and sometimes fatal. It can manifest with varied neurological presentations like meningoencephalitis, brain stem encephalitis, GBS etc. This can appear alone or with clinical picture of infectious mononucleosis. Establishing a diagnosis of EBV encephalitis is difficult and consequently molec...

We present the case of a male aged 74 years suffering from long-term rheumatoid arthritis with no pharmacological treatment. He visited the emergency department due to sudden loss of strength in both right limbs. In the preceding few months he had experienced asthenia and weight loss due to hyporexia. Physical examination revealed significant joint deformities, mild right hemiparesis with hyper...

Immunocompromised patients as those with renal transplant, hematological neoplasia or cancer and HIV/AIDS infection can suffer acute reactivation of Chagas disease. Central nervous system (CNS) evolvement (cerebral tumor or chagoma and diffuse meningoencephalitis) is similar to other opportunistic infections that present with cerebral expansive processes like toxoplasmosis or CNS primary lympho...

This paper describes the control, epidemiological, pathological, and molecular aspects of an outbreak of meningoencephalitis in calves due to bovine herpesvirus 5 at a feedlot with 540 animals in São Paulo State, Brazil. The introduction of new animals and contact between the resident animals and the introduced ones were most likely responsible for virus transmission. Bovine herpesvirus 1 vacci...

Locked-in syndrome is a rare clinical syndrome due to basilary artery thrombosis generally associated with trauma, vascular, or cardiac malformation. It can present as various types of clinical evolution and occasionally masquerades as other pathological conditions, such as infective meningoencephalitis. These complications are the cause of diagnostic delay, if not promptly recognised, followed...

A 3-year-old female pug presented with general seizure following a partial seizure. During the remaining 48 months till death, the dog showed various neurological signs such as disturbance of consciousness, myoclonus and various types of partial seizure after each occurrence of the seizure clusters, and the dog eventually exhibited inability to stand and dementia. Magnetic resonance imaging fin...

Although cryptococcal infections begin in the lungs, meningoencephalitis is the most frequently encountered manifestation of cryptococcosis among individuals with advanced immunosuppression. As the infection progresses along the Virchow-Robin spaces, these structures may become dilated with mucoid material produced by the capsule of the organism. We report a case of a 24-year-old man with crypt...

A 7-year-old boy with no prior illness or altered immunity presented to the emergency department with a 36-hour history of fever (103.7°F), emesis, headache, and lethargy. The patient had a history of swimming in a local lake the week before presentation. Physical examination revealed nuchal rigidity. Computed tomography (CT) of the head was normal. A lumbar puncture revealed a cerebrospinal fl...
