Overview
Other diagnostic studies for atypical teratoid rhabdoid tumor include biopsy (definitive diagnostic test), fluorescence in situ hybridization (abnormalities of chromosome 22q11.2), and immunohistochemistry (loss of INI-1 staining in the neoplastic cells).
Other Diagnostic Studies
Biopsy
Biopsy is performed for the definitive diagnosis of atypical teratoid rhabdoid tumor.[1]
Fluorescent In Situ Hybridization
Fluorescence in situ hybridization demonstrates abnormalities of chromosome 22q11.2.
Immunohistochemistry
Immunohistochemistry studies reveal the loss of INI-1 staining in the neoplastic cells confirming the diagnosis of atypical teratoid rhabdoid tumor.[2]
