Ribosome-lamella complexes in intracranial tumours.

A report is given of four intracranial tumours which contained ribosome-lamella complexes (RLCs). Three of the tumours were of neuroectodermal origin (two gangliogliomas and an astrocytoma), in which these structures have not previously been documented, and one was a haemangioblastoma. This study supports the view that RLCs may be related to abnormal protein synthesis.
