要旨

Rationale:

Echinococcosis is a zoonotic disease most commonly caused by the larval stage of Echinococcus granulosus. As an intermediate host, Homo sapiens primarily exhibits hepatic involvement. Although hepatic involvement is the typical presentation, disseminated multi-organ infection is exceedingly rare.

Patient Concerns:

The patient was a 22-year-old Tibetan male. He experienced an epileptic seizure 1 day prior, without an apparent cause, and occasionally lost consciousness, though there was no nausea or vomiting.

Diagnoses:

Cerebral echinococcosis, hepatic echinococcosis, and pulmonary echinococcosis.

Interventions:

Microsurgical excision of the hydatid cyst was performed to alleviate the intracranial pressure it exerted on the brain tissue.

Outcomes:

The patient experienced no obvious discomfort following the operation, and no abnormalities were detected during routine follow-ups. Consequently, the patient was discharged without complications. Currently, the patient has resumed a normal life, and ongoing treatment for liver and lung hydatid disease should continue.

Lessons:

We report on a rare case characterized by specific clinical manifestations. Additionally, we examine the role of blood transmission in the dissemination of the disease and evaluate the efficacy of surgical interventions.

Pulmonary Tuberculosis III

1.8K

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Encephalitis ll: Pathophysiology

Encephalitis is inflammation of the brain parenchyma caused by direct viral invasion or immune-mediated mechanisms triggered by infections or tumors. Both processes lead to neuronal injury, disrupted neurotransmission, and diverse neurological symptoms, often with overlapping clinical and pathological features.Autoimmune EncephalitisIn autoimmune encephalitis, antibodies target neuronal antigens on cell surfaces, synapses, or within neurons. A key example is anti-NMDAR encephalitis, which can...

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial...

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic...
