- encephalogram an X ray of the brain made by replacing spinal fluid with a gas (usually oxygen) to improve contrast
- pneumoencephalogram an X ray of the brain made by replacing spinal fluid with a gas (usually oxygen) to improve contrast
- encephalography roentgenography of the brain after spinal fluid has been replaced by a gas (usually oxygen); produces an encephalogram
- meningocele a congenital anomaly of the central nervous system in which a sac protruding from the brain or the spinal meninges contains cerebrospinal fluid (but no nerve tissue)
