Hydranencephaly is a condition in which the brain's cerebral hemispheres are absent to a great degree and the remaining cranial cavity is filled with cerebrospinal fluid. Transillumination can be used to diagnose hydranencephaly. The device used in this operation is a Chun gun that uses a 150 watt

presents as painless enlargement of the scrotum, similar to what may be encountered with testicular neoplasms. A convenient method to differentiate the conditions is to transilluminate the scrotum, as the hydrocele will appear a soft red while a solid tumor will not transmit light. Any uncertainty

In medicine transillumination generally refers to the transmission of light through tissues of the body. A common example is the transmission of light through fingers, producing a red glow due to red blood cells absorbing other wavelengths of light. Organs analysed include the sinuses, the breasts

There is brilliant transillumination in case of meningocele due to presence of CSF inside the cyst. Meningomyelocele, on the other hand, is partially transilluminant as it contains nerve root fibres along with the CSF.

to shine light in bodies of infants and observe the amount of scattered light. Since their skeleton is not fully calcified, light can easily penetrate tissues. Common examples of diagnostic applications are:

is the technique of sample illumination by transmission of light through the sample. Transillumination is used in a variety of methods of imaging.

Light bright enough to penetrate the shell can be used to verify egg yolks are intact, as the yolk is opaque while the albumin is transparent.
