In anatomy, the endolymphatic sac is a structure in the inner ear. It is a dead end pouch located at the end of the endolymphatic duct, on the posterior surface of the petrous portion of the temporal bone, where it is in contact with the dura mater.
Neoplasms of the endolymphatic sac are very rare tumors.
