Tumor of lateral cerebral ventricle Diagnosis

Some test use to diagnosis for lateral cerebral ventricle Tumor include:

1. Cerebrospinal fluid examination. Patients with increased cerebrospinal fluid pressure, cerebrospinal fluid protein content also increased, and for the highest indoor brain, lumbar and lower protein content winner. Tumor of the lateral ventricle with cerebrospinal fluid protein content is higher than in the contralateral lateral ventricle cerebrospinal fluid protein content. Cerebrospinal fluid cell count is slightly higher, and sometimes can be found in tumor cells.

2. Skull X-ray film. X-ray skull lateral ventricle tumors for a simple method, the X-ray signs manifested in two aspects:

  • signs of intracranial hypertension: the skull with traces increased pressure plate means; saddle area of bone changes in a post-clinoid bone or even disappear, shorter dorsal saddle, saddle-back severe cases, also disappeared; longer intracranial hypertension, atrophy skull bone thinning occurs;
  • tumor calcification: calcification, also known as intracranial tumor pathological calcification. Lateral ventricle tumor calcification is not uncommon, more common in ependymoma and choroid plexus papilloma. Ependymoma of the lateral ventricle showed calcification within the multi-scattered punctate aggregation consisting of multiple spherical calcification.

    Choroid plexus papilloma in the lateral ventricle occurred more than three districts, the calcification characteristics of unilateral lateral position within the triangle appears calcified, bilateral lateral triangle calcification occurred in parts of the choroid plexus is greater than the normal pattern of calcification. Meningioma mostly punctate calcification, flake, needle-like or radial.

    3. Cerebral angiography. Lateral ventricle tumor cerebral angiography in the main blood vessels show signs of hydrocephalus, the performance variable for the anterior cerebral artery or contralateral straight shift, sylvian artery can be mild or only the outward manifestations of displacement out of Hong Kong trend. Horizontal segment of middle cerebral artery and its branches curved upward shift, shift peripheral arterial corpus, round the knees, which led straight up above. Choroidal artery directly or downward shift change, or can be seen to expand into the choroidal artery tumor. Sometimes show abnormal blood vessels inside the brain Mission.

    4. Cerebral ventriculography. Cerebral ventriculography is a special significance test to lateral ventricle tumor diagnosed. It can show the tumor size and location, even confirmed diagnosis. Because lateral cerebral ventricle tumor easily blocked foramen of Monro, contrast can be seen when the ventricles expand and obvious to the tumor side, intraventricular filling defect and the tumor shadow can be seen. Lateral ventricle tumors larger triangle gas enveloping the brain imaging of the tumor can be seen, sometimes to the contralateral lateral shift can be seen.

    5. Other. Electroencephalogram (EEG) focal slow wave can be seen there. Ultrasound waves are midline shift. CT examination of the lateral ventricle of brain tumors may be an important basis for prompt and show that tumor size, shape and location, and sometimes can make the qualitative diagnosis.
