Summary
Parallel and concentric tubules were observed in the cytoplasm of arachnoid cells overlying cerebral gliomas. The parallel tubules were 400–500 Å wide. Their electron dense walls, 150 Å thick lay 200–250 Å apart with distensions up to 400 Å in diameter at irregular intervals between the walls. The walls formed terminal loops limiting up to 4 adjacent tubules; transverse extensions were present between adjacent walls. The tubules sometimes communicated with the rough endoplasmic reticulum from which they may possibly arise. The concentric tubules were 250 Å wide: they communicated at irregular intervals.
