Video: Bugs in the Brain – HIV and Toxoplasmosis

HIV-induced compromise of the immune system leaves afflicted persons vulnerable to a wide variety of infections.  In this video, we discuss the neuroradiology and pathologic findings of an HIV+ patient with a brain infection caused by the protozoan parasite: Toxoplasma gondii. https://youtu.be/9mBmgNLz13o

Leptomeningitis and Perivascular Spread

Many blood vessels that supply the brain and spinal cord initially run within the covering layers on the external surface, called the leptomeninges (also known as the pia-arachnoid), before plunging into the deeper neural tissue. As the vessel transitions from the outer layers into deeper tissue, the perivascular space immediately surrounding the vessel, called Virchow-Robin space, may provide a conduit for infectious/inflammatory processes. ...

Infection/Inflammation of Spine and Nerve Roots

The spinal cord is covered by protective outer connective tissue layers called the pia-arachnoid or leptomeninges.  Inflammatory or infectious processes that involve the leptomeninges, called leptomeningitis, can also involve the adjacent spinal nerve roots, which similarly have an outer covering of connective tissue that is continuous with the leptomeninges.  The image depicts a spinal cord with acute...
