Cerebral paragonimiasis

Introduction to brain schistosomiasis Pneumococcal disease is a disease in which the paragonimiasis is parasitic in the brain and is caused by mechanical damage caused by continuous migration, and its metabolites, etc., and the temporal lobe is most often damaged. The clinical manifestations of this disease are dizziness, headache, epilepsy, hemiplegia, visual impairment, etc., with systemic symptoms and fever. basic knowledge The proportion of illness: 0.003% Susceptible people: no special people Mode of infection: non-infectious Complications: pneumonia meningitis brain subarachnoid hemorrhage abscess

Causes of brain paragonimiasis

The pathogenicity of Paragonimus is mainly the migration of adult or adult worms in human tissues and organs, the mechanical damage caused by colonization, and the immunopathological reactions caused by metabolites.

Prevention of brain paragonimiasis

Publicize and educate local residents and tourists not to eat raw food or half-life crabs, cockroaches and their products; to talk about hygiene, not to drink raw water, is the most important measure to prevent this disease.

Complications of brain paragonimiasis Complications pneumonia meningitis brain subarachnoid hemorrhage abscess

Easy to combine chest and lung type, abdominal type, skin type, may have pneumonia and meningitis symptoms, brain subarachnoid hemorrhage, abscess, cyst and other complications.

Symptoms of cerebral paragonimiasis Common symptoms Abdominal pain, fever, diarrhea, blood in the stool

The clinical manifestations of this disease are dizziness, headache, epilepsy, hemiplegia, visual impairment, etc., with systemic symptoms and fever.

Combined abdominal type: abdominal pain, diarrhea, bloody stool and so on.

Combined skin type: transitional subcutaneous mass, nodules, etc.

Combined chest and lung type: cough, chest pain, blood in the sputum or cough rust.

The above classification is not absolute, and there are often many cases in which the same patient is present in the clinic.

Examination of cerebral paragonimiasis

Pathogen diagnosis

(1) Cerebrospinal fluid, sputum or stool examination can be used to detect and collect eggs.

(2) Biopsy: Subcutaneous mass or nodular surgical removal may reveal child worms, or typical pathological changes.

2. Immunoassay

(1) Intradermal test: commonly used for census, the positive coincidence rate can be as high as 95% or more, but often there are false positives and false negatives.

(2) Enzyme-linked immunosorbent assay: high sensitivity, positive rate of 90% to 100%.

(3) Circulating antigen detection: The circulating antigen in serum was directly detected by enzyme-linked immunosorbent antigen spot test (AST-ELISA), and the positive rate was above 98%, and it can be used as a therapeutic evaluation.

3. Check

Skull CT scan and magnetic resonance examination showed cysts, and the skull slices had calcification of the cyst wall. For example, the chest lung type was combined, and the lungs showed obvious changes in the lungs.

Diagnosis and identification of cerebral paragonimiasis

Diagnosis can be based on medical history, clinical symptoms, and laboratory findings.

Differential diagnosis

1. Different from other meningitis, encephalitis and space-occupying lesions, the eggs can be detected by means of cerebrospinal fluid, sputum or stool examination, and can be identified by immunological detection methods.

2. The combination of chest and lung type is easily misdiagnosed as tuberculosis or pneumonia. Cerebrospinal fluid, sputum or stool examination can be used to identify the paragonimus eggs, which can be identified by immunological detection methods.
