Overview
Other Diagnostic Studies
Fluorescent in-situ hybridization (FISH) technique
- FISH demonstrates deletions of chromosome 1p and 19q.[1]
Biopsy
Biopsy demonstrates
- Biopsy may be of two types: open or stereotactic.
- Indications of stereotactic biopsy include:
- Deep-seated tumor that is not amenable to resection
- Lesions in which the radiological and clinical findings are ambiguous
- Diffuse lesions; multiple lesions; an appearance that suggests a lymphoma, which would not require resection
- Change in the appearance of a previously diagnosed or treated tumor
- Assessment of tumor after treatment
- Biopsy may be done at the time of surgical resection of gliomatosis cerebri.
- Biopsy may be performed to help confirm the diagnosis of gliomatosis cerebri.
