Endolymphatic sac tumor metastatic to the spine. Case report

J Neurosurg Spine. 2005 Jul;3(1):68-70. doi: 10.3171/spi.2005.3.1.0068.


Endolymphatic sac tumors (ELSTs) are aggressive papillary lesions of the temporal bone. Although histologically benign, they may exhibit invasive growth and destruction of the skull base. Patients generally present with symptoms referable to the lesion's location within the middle or posterior cranial fossa. Although well characterized as a distinct entity, ELSTs involved in metastatic dissemination have never been reported. In the present report the authors describe a case of ELST metastatic to the spine treated with resection.
