SARS-CoV-2-associated haemorrhagic encephalitis mimicking Herpes encephalitis.

Although acute encephalopathy is quite commonly seen in patients of SARS-CoV-2 infection, encephalitis characterised by brain inflammation is relatively rare. Encephalitis caused by Herpes simplex type 1 is the most common cause of identified sporadic encephalitis, and early diagnosis and prompt treatment can prevent the devastating outcome. In this brief communication, we report a case of SARS-CoV-2 associated haemorrhagic encephalitis mimicking herpes encephalitis.

Curious case of steroid responsive diffuse anterior horn cell disease associated with COVID-19 infection.

Covid-19-associated neurological manifestations are being reported with increased frequency throughout the world. In a study from China, symptoms referable to peripheral nervous system (PNS) were described in approximately 9% of hospitalized Covid-19 patients. Common PNS symptoms reported in the study were loss of taste/smell and muscle pains.

Paraneoplastic cerebellar degeneration as a presenting manifestation of non-Hodgkin's lymphoma.

Background: Paraneoplastic Cerebellar degeneration (PCD) is one of the classical paraneoplastic syndromes (PNS) which is characterised by subacute onset, progressive cerebellar ataxia and is usually associated with small cell lung carcinoma, adeno carcinoma of breast and ovary followed by Hodgkin's lymphoma.

Objective: We herein report a case of subacute onset, progressive cerebellar ataxia in a 37-year-old female, who on evaluation was found to have non-Hodgkin's lymphoma and experienced good clinical response to treatment.

Discussion: As compared to solid tumours, chances of association of PNS with Lymphomas is quite low and there are only few case reports in the literature showing association of PCD with non-Hodgkin's lymphoma.

Covid-19 associated Guillain-Barre Syndrome: Contrasting tale of four patients from a tertiary care centre in India.

Background: Globally, more than 12 million people have been infected with COVID -19 infection till date with more than 500,000 fatalities. Although, Covid-19 commonly presents with marked respiratory symptoms in the form of cough and dyspnoea, a neurotropic presentation has been described of late as well.

Objective: In this brief communication we report four cases of Covid-19 who presented to our hospital with features suggestive of Guillain-Barre Syndrome (GBS).
