Testicular swellings and transillumination mnemonic


In today's post, I'll be shedding light on your testes! :P

For those who don't know what transillumination is, it is shining of light through a swelling and seeing if the light is transmitted through it or not.

In this post, I'll be talking about swelling of testes.

The general rule is, any fluid collection in the testes will transilluminate.

Hydrocele: What is it? Fluid collection in the tunica vaginalis. It will transmit light and transilluminate.

Spermatocele: What is it? Cystic accumulation of sperms. It's (kinda) clear fluid and will transilluminate.

Hematocele: What is it? Blood accumulation. This one's kind of tricky because even though it's a fluid collection, RBC's are dense. So it does not transilluminate well.

Testicular swellings that do not transilluminate: Hernias, testicular tumors and varicoceles.

Here's a mnemonic: "SHINe" xD
